We apply a practical alternative to allocating a portion of the transaction price to the material right performance obligation and estimate a hypothetical transaction price which includes fees for expected maintenance renewals based on the estimated economic life of the perpetual license contracts.

We have elected to not recognize a lease liability or ROU asset for short-term leases (leases with a term of twelve months or less). For contracts with lease and non-lease components, we have elected to not allocate the contract consideration, and account for the lease and non-lease components as a single lease component. Additionally, we enter into arrangements to use shared office spaces and other facilities, and have determined that these arrangements do not contain leases as we do not have the right to use an identified asset. Operating leases are included in operating lease ROU assets, operating lease liabilities and operating lease liabilities (net of current portion) in our consolidated balance sheets. Finance leases are included in property and equipment, other current liabilities and other liabilities in our consolidated balance sheets. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments under the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The implicit rate within our operating leases is generally not determinable and we use our incremental borrowing rate at the lease commencement date to determine the present value of lease payments. The determination of our incremental borrowing rate requires judgment. We determine our incremental borrowing rate for each lease using our current borrowing rate, adjusted for various factors including level of collateralization, term and currency to align with the terms of the lease. The operating lease ROU asset also includes any lease prepayments, offset by lease incentives. Certain of our leases include options to extend or terminate the lease. An option to extend the lease is considered in connection with determining the ROU asset and lease liability when it is reasonably certain we will exercise that option. An option to terminate is considered unless it is reasonably certain we will not exercise the option.</span></div></ix:nonNumeric></ix:continuation><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">11</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><ix:continuation id="TextSelection-AF3B450C9D247C53DC0C1AAC95DF86FA-5"><ix:continuation id="TextSelection-503C6347703A545CB2D01AAC95DF5494-1"><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Lease expense for lease payments is recognized on a straight-line basis over the term of the lease.</span></div></ix:continuation><ix:nonNumeric contextRef="FD2019Q2YTD" name="us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock" id="TextSelection-F1485750B8C25BD665E61AAC95DFB40E-0-wk-Fact-FA304EB96ECC82F2B6371AAC95B842EC" escape="true"><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Recent Accounting Pronouncements Not Yet Adopted</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13 &#8212;&#160;</span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Financial Instruments-Credit Losses (Topic 326)</span><span style="font-family:Arial;font-size:10pt;">:</span><span style="font-family:Arial;font-size:10pt;font-style:italic;"> Measurement of Credit Losses on Financial Instruments</span><span style="font-family:Arial;font-size:10pt;">.

Cyber Exposure is a discipline for managing and measuring cybersecurity risk in the digital era. Our enterprise platform enables broad visibility into an organization&#8217;s cyber exposure across the modern attack surface and deep insights that help organizations translate vulnerability data into business insights to understand and reduce their cybersecurity risk. </span></div><div style="line-height:120%;padding-bottom:16px;padding-top:8px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our enterprise platform offerings, including Tenable.io, Tenable.sc and Industrial Security, are built to provide organizations with the breadth of visibility to accurately understand both traditional and modern attack surfaces and the depth of insight that stems from risk-based analytics, prioritization and benchmarking. Our Cyber Exposure platform automatically discovers assets, including those in cloud environments, and assesses these assets for the presence of vulnerabilities, internal and regulatory compliance violations, misconfigurations and other cybersecurity issues, analyzes and prioritizes cybersecurity risks based on the likelihood of a vulnerability being exploited and the business criticality of the asset, and provides an objective way to measure an organization&#8217;s cyber exposure.</span></div><div style="line-height:120%;padding-bottom:16px;padding-top:8px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our enterprise platform offerings are primarily sold on a subscription basis with a one year term. Our subscription terms are generally not longer than three years. These offerings are typically prepaid in advance. To a lesser extent, we generate ratably recognizable revenue from perpetual licenses and from the related ongoing maintenance. </span></div><div style="line-height:120%;padding-bottom:16px;padding-top:8px;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We sell and market our products and services through our field sales force that works closely with our channel partners, which includes a network of distributors and resellers, in developing sales opportunities. We use a&#160;two-tiered&#160;channel model whereby we sell our enterprise platform offerings to our distributors, which in turn sell to our resellers, which then sell to end users, which we call customers.</span></div><div style="line-height:120%;padding-bottom:16px;padding-top:8px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Many of our enterprise platform customers initially use either our free or paid version of Nessus, one of the industry&#8217;s most widely deployed vulnerability assessment solutions. Nessus, which is the technology that underpins our enterprise platform offerings, is designed to quickly and accurately identify vulnerabilities, configuration and compliance issues and malware. Our free version of Nessus, Nessus Essentials, allows for vulnerability assessment over a limited number of IP addresses. We believe many of our Nessus customers begin with Nessus Essentials and subsequently upgrade to Nessus Professional, the paid version of Nessus; however, we expect many users to continue to use Nessus Essentials.&#160;</span></div><div style="line-height:120%;padding-bottom:16px;padding-top:8px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We have experienced rapid growth in recent years.

We present these operating metrics and non-GAAP&#160;financial measures to assist investors in seeing our operating and financial performance using a management view and because we believe that these measures provide an additional tool for investors to use in comparing our core operating and financial performance over multiple periods with other companies in our industry. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Calculated Current Billings</span><span style="font-family:Arial;font-size:10pt;font-style:italic;"> </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We use the non-GAAP measure of calculated current billings, which we believe is a key metric to measure our periodic performance. Given that most of our customers pay in advance, we typically recognize a majority of the related revenue ratably over time. We use calculated current billings to measure and monitor our ability to provide our business with the working capital generated by upfront payments from our customers. </span></div><div style="line-height:120%;padding-bottom:16px;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Calculated current billings consists of revenue recognized in a period plus the change in current deferred revenue in the corresponding period. We believe that calculated current billings, which excludes deferred revenue for periods beyond twelve months in a customer&#8217;s contractual term, more closely correlates with annual contract value and that the variability in total billings, depending on the timing of large multi-year contracts and the preference for annual billing versus multi-year upfront billing, may distort growth in one period over another. While we believe that calculated current billings provides valuable insight into the cash that will be generated from sales of our subscriptions, this metric may vary from period-to-period for a number of reasons, and therefore has a number of limitations as a quarter-to-quarter or year-over-year comparative measure. For example, calculated current billings include amounts that have not yet been recognized as revenue; an increasing number of large sales transactions, for which the timing has and will continue to vary, may occur in quarters subsequent to or in advance of those that we anticipate; and our calculation of current billings may be different from other companies that report similar financial measures. Additionally, calculated current billings in any one period may be impacted by the timing of customer renewals, including early renewals, which could favorably or unfavorably impact year-over-year comparisons. Because of these and other limitations, you should consider calculated current billings along with revenue and our other GAAP financial results.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The adoption of Accounting Standards Codification Topic 606,&#160;</span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Revenue From Contracts With Customers</span><span style="font-family:Arial;font-size:10pt;">&#160;at&#160;January&#160;1, 2017 included a $55.0 million increase to deferred revenue primarily related to the deferral of perpetual license revenue. This cumulative adjustment to deferred revenue at January 1, 2017 increased calculated current billings $16.7 million in 2017 and $11.8 million in 2018 and is expected to increase calculated current

First, free cash flow is not a substitute for net cash flows from operating activities. Second, other companies may calculate free cash flow or similarly titled non-GAAP financial measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of free cash flow as a tool for comparison. Additionally, the utility of free cash flow is further limited as it does not reflect our future contractual commitments and does not represent the total increase or decrease in our cash balance for a given period. Because of these and other limitations, you should consider free cash flow along with net cash (used in) provided by operating activities and our other GAAP financial measures.</span></div><div

financial performance, along with non-GAAP operating margin, which is calculated as non-GAAP loss from operations divided by our revenue in the period. We believe that these non-GAAP financial measures provide useful information about our core operating results over multiple periods. There are a number of limitations related to the use of the non-GAAP financial measures as compared to GAAP loss from operations and operating margin, including that non-GAAP loss from operations and non-GAAP operating margin exclude stock-based compensation expense, which has been, and will continue to be for the foreseeable future, a significant recurring expense in our business and an important part of our compensation strategy. </span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span

accretion of Series A and B redeemable convertible preferred stock, stock-based compensation and amortization of intangible assets, as well as the related tax impact, to calculate non-GAAP net loss per share and pro forma non-GAAP net loss per share. Pro forma non-GAAP net loss per share is calculated by giving effect to the conversion of our redeemable convertible preferred stock into common stock as though the conversion occurred at the beginning of each period presented prior to 2019. We believe that these non-GAAP measures provide important information to management and investors because they facilitate comparisons of our core operating results over multiple periods.

Perpetual license arrangements generally contain a material right related to the customer&#8217;s ability to renew maintenance at a price that is less than the initial license fee. We apply a practical alternative to allocating a portion of the transaction price to the material right performance obligation and estimate a hypothetical transaction price which includes fees for expected maintenance renewals based on the estimated economic life of perpetual license contracts. We allocate the transaction price between the cybersecurity subscription provided in the initial contract and the material right related to expected contract renewals based on the hypothetical transaction price. We recognize the amount allocated to the combined license and maintenance performance obligation over the initial contractual period, which is generally one year. We recognize the amount allocated to the material right over the expected maintenance renewal period, which begins at the end of the initial contractual term and is generally four years. We have estimated the five-year economic life of perpetual license contracts based on historical contract attrition, expected renewal periods, the lifecycle of our technology and other factors. This estimate may change over time.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Professional services and other revenue is primarily comprised of advisory services and training related to the deployment and optimization of our products.

style="font-family:Arial;font-size:10pt;">June 30, 2019</span><span style="font-family:Arial;font-size:10pt;">, we had cash and cash equivalents consisting of bank deposits, commercial paper and money market funds of </span><span style="font-family:Arial;font-size:10pt;">$185.7 million</span><span style="font-family:Arial;font-size:10pt;"> and short-term investments consisting of commercial paper,

</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Since our inception and prior to our IPO, we financed our operations through cash provided by operations, including payments received from customers using our software products and services, and we did not raise any primary institutional capital prior to our IPO. The proceeds of our Series A and Series B redeemable convertible preferred stock financings were used to repurchase shares of capital stock from former stockholders. We have generated significant operating losses from our operations as reflected by our accumulated deficit of </span><span style="font-family:Arial;font-size:10pt;">$509.2 million</span><span style="font-family:Arial;font-size:10pt;"> at </span><span style="font-family:Arial;font-size:10pt;">June 30, 2019</span><span style="font-family:Arial;font-size:10pt;">. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We typically invoice our customers annually in advance and, to a lesser extent, multi-year in advance. Therefore, a substantial source of our cash is from such prepayments, which are included on our consolidated balance sheets as deferred revenue. Deferred revenue consists primarily of the unearned portion of billed fees for our subscriptions and perpetual licenses, which is subsequently recognized as revenue in accordance with our revenue recognition policy. At </span><span style="font-family:Arial;font-size:10pt;">June 30, 2019</span><span style="font-family:Arial;font-size:10pt;">, we had deferred revenue of </span><span style="font-family:Arial;font-size:10pt;">$307.3 million</span><span style="font-family:Arial;font-size:10pt;">, of which </span><span style="font-family:Arial;font-size:10pt;">$227.2 million</span><span style="font-family:Arial;font-size:10pt;"> was recorded as a current liability and is expected to be recorded as revenue in the next 12&#160;months, provided all other revenue recognition criteria are met.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our principal uses of cash in recent periods have been funding our operations, expansion of our sales and marketing and research and development activities and investments in infrastructure. We expect to continue incurring operating losses and generating negative cash flows from operations in the near-term; however, we believe that our existing cash and cash equivalents and short-term investments will be sufficient to fund our operating and capital needs for at least the next 12 months. Our future capital requirements will depend on many factors, including our revenue growth rate, subscription renewal activity, the timing and extent of spending to support further infrastructure and research and development efforts, the timing and extent of additional capital expenditures to invest in new and existing office spaces, such as our new corporate headquarters, the expansion of sales and marketing and international operating activities, the timing of introduction of new product capabilities and enhancements of our platform and the continuing market acceptance of our platform. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We may in the future enter into arrangements to acquire or invest in complementary businesses, services and technologies, including intellectual property rights. We may be required to seek equity or debt financing. In the event that financing is required from outside sources, we may not be able to raise it on terms acceptable to us or at all. If we are unable to raise additional capital when desired, or if we cannot expand our operations or otherwise capitalize on our business opportunities because we lack sufficient capital, our business, operating results and financial condition would be adversely affected. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Credit Facility</span><span style="font-family:Arial;font-size:10pt;font-style:italic;"> </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In May 2017, we entered into a </span><span style="font-family:Arial;font-size:10pt;">$25.0 million</span><span style="font-family:Arial;font-size:10pt;"> revolving credit facility with Silicon Valley Bank. Pursuant to the terms of the revolving credit facility, we may issue up to </span><span style="font-family:Arial;font-size:10pt;">$5.0 million</span><span style="font-family:Arial;font-size:10pt;"> of letters of credit, which reduce the total amount available for borrowing under such facility. The revolving credit facility terminates on May&#160;4, 2020.

If, as of the last day of any quarter, the outstanding balance of the revolving credit facility exceeds $5.0&#160;million, there are financial covenants that require us to maintain a minimum level of earnings before income taxes, interest, depreciation and amortization adjusted to add changes in deferred revenue in the period and a minimum current ratio level.

Our investments are carried at their fair market value with cumulative unrealized gains or losses recorded as a component of accumulated other comprehensive income (loss) within stockholders' equity. The primary objectives of our investment activities are the preservation of capital, the fulfillment of liquidity needs and the fiduciary control of cash and investments. We do not enter into investments for trading or speculative purposes. Interest-earning instruments carry a degree of interest rate risk; however, a hypothetical 10% change in interest rates during any of the periods presented would not have had a material impact on our financial statements. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We have not had any amounts outstanding under the revolving credit facility since it was established in May 2017.

A portion of our operating expenses are incurred outside the United States, denominated in foreign currencies and subject to fluctuations due to changes in foreign currency exchange rates, particularly changes in the Euro, British Pound and Australian dollar. Additionally, fluctuations in foreign currency exchange rates may cause us to recognize remeasurement and transaction gains (losses) in our consolidated statements of operations. As the impact of foreign currency exchange rates has not been material to our historical operating results, we have not entered into derivative or hedging transactions, but we may do so in the future if our exposure to foreign currency becomes more significant. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Inflation Risk</span><span style="font-family:Arial;font-size:10pt;font-style:italic;"> </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We do not believe that inflation has had a material effect on our business, results of operations, or financial condition.

Our management, including our Chief Executive Officer and Chief Financial Officer, believes that our disclosure controls and procedures and internal control over financial reporting are designed to provide reasonable assurance of achieving their objectives and are effective at the reasonable assurance level.

Any success that we may experience in the future will depend in large part on our ability to, among other things:</span></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><span style="font-family:Arial;font-size:10pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">maintain and expand our customer base;</span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><span style="font-family:Arial;font-size:10pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">increase revenue from existing customers through increased or broader use of our offerings within their organizations;</span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><span style="font-family:Arial;font-size:10pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">improve the performance and capabilities of our offerings through research and development;</span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><span style="font-family:Arial;font-size:10pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">continue to develop and expand our enterprise platform;</span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><span style="font-family:Arial;font-size:10pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">maintain the rate at which customers purchase and renew subscriptions to our enterprise platform offerings;</span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><span style="font-family:Arial;font-size:10pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">continue to successfully expand our business domestically and internationally; and</span></div></td></tr></table><table cellpadding="0" cellspacing="0" style="padding-bottom:16px;font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:10pt;padding-left:24px;"><span style="font-family:Arial;font-size:10pt;">&#8226;</span></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">successfully compete with other companies.</span></div></td></tr></table><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">If we are unable to maintain consistent revenue or revenue growth, our stock price could be volatile, and it may be difficult to achieve and maintain profitability.

As a result, a substantial portion of the revenue that we report in each period will be derived from the recognition of deferred revenue relating to agreements entered into during previous periods. Consequently, a decline in new sales or renewals in any one period may not be immediately reflected in our revenue results for that period. This decline, however, will negatively affect our revenue in future periods. Accordingly, the effect of significant downturns in sales and market acceptance of our solutions and potential changes in our rate of renewals may not be fully reflected in our results of operations until future periods. This also makes it difficult for us to rapidly increase our revenue growth through additional sales in any period, as revenue from new customers generally will be recognized over the term of the applicable agreement.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">We may not be able to scale our business quickly enough to meet our customers&#8217; growing needs.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">As usage of our enterprise platform grows, and as customers expand in size or expand the number of IT assets or IP addresses under their subscriptions, we may need to devote additional resources to improving our technology architecture, integrating with third-party systems and maintaining infrastructure performance. In addition, we will need to appropriately scale our sales and marketing headcount, as well as grow our third-party channel partner network, to serve our growing customer base. If we are unable to scale our business appropriately, it could reduce the attractiveness of our solutions to customers, resulting in decreased sales to new customers, lower renewal rates by existing customers or the issuance of service credits or requested refunds, each of which could hurt our revenue growth and our reputation. Even if we are able to upgrade our systems and expand our personnel, any such expansion will be expensive and complex, requiring management time and attention. We could also face inefficiencies or operational failures as a result of our efforts to scale our infrastructure. Moreover, there are inherent risks associated with upgrading, improving and expanding our information technology systems. We cannot be sure that the expansion and improvements to our infrastructure and systems will be fully or effectively implemented on a timely basis, if at all. These efforts may reduce revenue and our margins and adversely impact our financial results.</span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">39</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">If our enterprise platform offerings do not interoperate with our customers&#8217; network and security infrastructure or with third-party products, websites or services, our results of operations may be harmed.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our enterprise platform offerings, Tenable.io and Tenable.sc, must interoperate with our customers&#8217; existing network and security infrastructure. These complex systems are developed, delivered and maintained by the customer and a myriad of vendors and service providers. As a result, the components of our customers&#8217; infrastructure have different specifications, rapidly evolve, utilize multiple protocol standards, include multiple versions and generations of products and may be highly customized. We must be able to interoperate and provide our security offerings to customers with highly complex and customized networks, which requires careful planning and execution between our customers, our customer support teams and our channel partners. Further, when new or updated elements of our customers&#8217; infrastructure or new industry standards or protocols, such as HTTP/2, are introduced, we may have to update or enhance our cloud platform and our other solutions to allow us to continue to provide service to customers. Our competitors or other vendors may refuse to work with us to allow their products to interoperate with our solutions, which could make it difficult for our cloud platform to function properly in customer networks that include these third-party products.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We may not deliver or maintain interoperability quickly or cost-effectively, or at all. These efforts require capital investment and engineering resources. If we fail to maintain compatibility of our cloud platform and our other solutions with our customers&#8217; network and security infrastructures, our customers may not be able to fully utilize our solutions, and we may, among other consequences, lose or fail to increase our market share and experience reduced demand for our services, which would materially harm our business, operating results and financial condition.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">If our solutions fail to detect vulnerabilities or incorrectly detect vulnerabilities, or if they contain undetected errors or defects, our brand and reputation could be harmed.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">If our solutions fail to detect vulnerabilities in our customers&#8217; cybersecurity infrastructure, or if our solutions fail to identify new and increasingly complex methods of cyberattacks, our business and reputation may suffer. There is no guarantee that our solutions will detect all vulnerabilities, especially in light of the rapidly changing security landscape to which we must respond. Additionally, our solutions may falsely detect vulnerabilities or threats that do not actually exist. For example, our solutions rely on information provided by an active community of users who contribute new exploits, attacks and vulnerabilities. If the information from these third parties is inaccurate, the potential for false indications of security vulnerabilities increases. These false positives, while typical in the industry, may impair the perceived reliability of our offerings and may therefore adversely impact market acceptance of our products and could result in negative publicity, loss of customers and sales and increased costs to remedy any problem.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our solutions may also contain undetected errors or defects when first introduced or as new versions are released. We have experienced these errors or defects in the past in connection with new solutions and product upgrades and we expect that these errors or defects will be found from time to time in the future in new or enhanced solutions after commercial release. Defects may cause our solutions to be vulnerable to attacks, cause them to fail to detect vulnerabilities, or temporarily interrupt customers&#8217; networking traffic. Any errors, defects, disruptions in service or other performance problems with our solutions may damage our customers&#8217; business and could hurt our reputation. If our solutions fail to detect vulnerabilities for any reason, we may incur significant costs, the attention of our key personnel could be diverted, our customers may delay or withhold payment to us or elect not to renew or other significant customer relations problems may arise. We may also be subject to liability claims for damages related to errors or defects in our solutions. A material liability claim or other occurrence that harms our reputation or decreases market acceptance of our solutions may harm our business and operating results.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">An actual or perceived security breach or theft of the sensitive data of one of our customers, regardless of whether the breach is attributable to the failure of our solutions, could adversely affect the market&#8217;s perception of our brand and our offerings and subject us to legal claims.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Our future quarterly results of operations are likely to fluctuate significantly due to a wide range of factors, which makes our future results difficult to predict.</span></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our revenue and results of operations have historically varied from period to period, and we expect that they will continue to do so as a result of a number of factors, many of which are outside of our control, including:</span></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman;

We typically enter into a significantly higher percentage of agreements with new customers, as well as renewal agreements with existing customers, in the third and fourth quarters. The increase in customer agreements in the third quarter is primarily attributable to U.S. government and related agencies, and the increase in the fourth quarter is primarily attributable to large enterprise account buying patterns typical in the software industry. We expect that seasonality will continue to affect our operating results in the future and may reduce our ability to predict cash flow and optimize the timing of our operating expenses.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">We face intense competition.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The market for cybersecurity solutions is fragmented, intensely competitive and constantly evolving. We compete with a range of established and emerging cybersecurity software and services vendors, as well as homegrown solutions. With the introduction of new technologies and market entrants, we expect the competitive environment to remain intense going forward. Our competitors include: vulnerability management and assessment vendors, including Qualys and Rapid7; diversified security software and services vendors, including IBM; endpoint security vendors with nascent vulnerability assessment capabilities, including Tanium and CrowdStrike; and providers of point solutions that compete with some of the features present in our solutions. We also compete against internally-developed efforts that often use open source solutions.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Some of our actual and potential competitors have significant advantages over us, such as longer operating histories, significantly greater financial, technical, marketing or other resources, stronger brand and business user recognition, larger intellectual property portfolios and broader global distribution and presence. In addition, our industry </span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">41</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">is evolving rapidly and is becoming increasingly competitive. Larger and more established companies may focus on cybersecurity and could directly compete with us. Smaller companies could also launch new products and services that we do not offer and that could gain market acceptance quickly.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our competitors may be able to respond more quickly and effectively than we can to new or changing opportunities, technologies, standards or customer requirements or new or evolving attacks by, or indicators of compromise that identify, cyber bad actors. With the introduction of new technologies, the evolution of our offerings and new market entrants, we expect competition to intensify in the future. In addition, some of our larger competitors have substantially broader product offerings and can bundle competing products and services with other software offerings. As a result, customers may choose a bundled product offering from our competitors, even if individual products have more limited functionality than our solutions. These competitors may also offer their products at a lower price as part of this larger sale, which could increase pricing pressure on our offerings and cause the average sales price for our offerings to decline. These larger competitors are also often in a better position to withstand any significant reduction in capital spending, and will therefore not be as susceptible to economic downturns. One component of our enterprise platform involves assessing Cyber Exposure in a public cloud environment. We are dependent upon the public cloud providers to allow our solutions to access their cloud offerings. If one or more cloud providers elected to offer exclusively their own cloud security product or otherwise eliminate the ability of our solutions to access their cloud on behalf of our customers, our business and financial results could be harmed.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Furthermore, our current and potential competitors may establish cooperative relationships among themselves or with third parties that may further enhance their resources and products and services offerings in the markets we address. In addition, current or potential competitors may be acquired by third parties with greater available resources. As a result of such relationships and acquisitions, our current or potential competitors might be able to adapt more quickly to new technologies and customer needs, devote greater resources to the promotion or sale of their products and services, initiate or withstand substantial price competition, take advantage of other opportunities more readily or develop and expand their product and service offerings more quickly than we do. For all of these reasons, we may not be able to compete successfully against our current or future competitors.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">If we do not continue to innovate and offer solutions that address the dynamic cybersecurity landscape, we may not remain competitive.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The cybersecurity market is characterized by very rapid technological advances, changes in customer requirements, frequent new product introductions and enhancements and evolving industry standards. Our success also depends on continued innovation to provide features that make our solutions responsive to the cybersecurity landscape. While we continue to invest significant resources in research and development in order to ensure that our solutions continue to address the cyber security risks that our customers face, the introduction of solutions and services embodying new technologies could render our existing solutions or services obsolete or less attractive to customers. In addition, developing new solutions and product enhancements is expensive and time-consuming, and there is no assurance that such activities will result in significant cost savings, revenue or other expected benefits. For example, we plan to release a new product, Tenable Lumin, and there can be no assurance that product will offer the benefits we expect or generate customer interest. We may also face delays or uncertainty in our release timing for Tenable Lumin that may be costly or reduce its benefits. If we spend significant time and effort on research and development and are unable to generate an adequate return on our investment, our business and results of operations may be materially and adversely affected. Further, we may not be able to successfully anticipate or adapt to changing technology or customer requirements or the dynamic threat landscape on a timely basis, or at all, which would impair our ability to execute on our business strategy.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Our business and results of operations depend substantially on our customers renewing their subscriptions with us and expanding the number of IT assets or IP addresses under their subscriptions. Any decline in our customer renewals, terminations or failure to convince our customers to expand their use of subscription offerings would harm our business, results of operations, and financial condition.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our subscription offerings are term-based and a majority of our subscription contracts are for one year in duration. In order for us to maintain or improve our results of operations, it is important that a high percentage of our customers renew their subscriptions with us when the existing subscription term expires, and renew on the same or more favorable terms. Our customers have no obligation to renew their subscriptions, and we may not be able to accurately predict customer renewal rates. In addition, the growth of our business depends in part on our customers expanding their use of subscription offerings and related services. Historically, some of our customers have elected not to renew their subscriptions with us for a variety of reasons, including as a result of changes in their strategic IT priorities, </span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">42</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">budgets, costs and, in some instances, due to competing solutions. Our retention rate may also decline or fluctuate as a result of a number of other factors, including our customers&#8217; satisfaction or dissatisfaction with our software, the increase in the contract value of subscription and support contracts from new customers, the effectiveness of our customer support services, our pricing, the prices of competing products or services, mergers and acquisitions affecting our customer base, global economic conditions, and the other risk factors described in this Quarterly Report on Form 10-Q. Additionally, many of our customers, including certain top customers, have the right to terminate their agreements with us for convenience and for other reasons. We cannot assure you that customers will maintain their agreements with us, renew subscriptions or increase their usage of our software. If our customers do not maintain or renew their subscriptions or renew on less favorable terms, or if we are unable to expand our customers&#8217; use of our software, our business, results of operations, and financial condition may be harmed.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In addition, while customers are typically invoiced in advance, including multi-year contracts, and our contracts generally do not provide for refunds during the subscription or maintenance period, a small number of customers could take the position that provisions in their customer agreements give them the right to terminate their agreement with us, or allege a material breach of their agreement with us, due to or in connection with the sale of our common stock. Early termination of these customer agreements for these reasons would generally only allow us to retain fees already paid by the customer for services rendered prior to the termination. Termination of these agreements, or allegations that we have breached one of these agreements with them, could decrease our customer revenue and increase legal and administrative costs.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Our brand, reputation and ability to attract, retain and serve our customers are dependent in part upon the reliable performance of our solutions and network infrastructure.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We have experienced, and may in the future experience, disruptions, outages and other performance problems due to a variety of factors, including infrastructure changes, human or software errors, capacity constraints and fraud or cybersecurity attacks. In some instances, we may not be able to identify the cause or causes of these performance problems within an acceptable period of time.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Prolonged delays or unforeseen difficulties in connection with adding capacity or upgrading our network architecture when required may cause our service quality to suffer. Problems with the reliability or security of our systems could harm our reputation. Damage to our reputation and the cost of remedying these problems could negatively affect our business, financial condition, and operating results.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Any disruptions or other performance problems with our solutions could harm our reputation and business and may damage our customers&#8217; businesses. Interruptions in our service delivery might reduce our revenue, cause us to issue credits to customers, subject us to potential liability and cause customers to not renew their purchases of our solutions.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">We must maintain and enhance our brand.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We believe that developing and maintaining widespread awareness of our brand in a cost-effective manner is critical to achieving widespread acceptance of our enterprise platform and attracting new customers. Brand promotion activities may not generate customer awareness or increase revenue and, even if they do, any increase in revenue may not offset the expenses we incur in building our brand. If we fail to successfully promote and maintain our brand, or incur substantial expenses, we may fail to attract or retain customers necessary to realize a sufficient return on our brand-building efforts, or to achieve the widespread brand awareness that is critical for broad customer adoption of our solutions.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">We rely on third parties to maintain and operate certain elements of our network infrastructure.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We utilize data centers located in North America, Europe and Asia to operate and maintain certain elements of our own network infrastructure. Some elements of this complex system are operated by third parties that we do not control and that could require significant time to replace. We expect this dependence on third parties to continue. For example, Tenable.io is hosted on Amazon Web Services, or AWS, which provides us with computing and storage capacity. Interruptions in our systems or the third-party systems on which we rely, particularly AWS, whether due to system failures, computer viruses, physical or electronic break-ins or other factors, could affect the security or availability of our solutions, network infrastructure and website.</span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">43</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our existing data center facilities and third-party hosting providers have no obligations to renew their agreements with us on commercially reasonable terms or at all, and certain of the agreements governing these relationships may be terminated by either party at any time, with no or limited notice. For example, our agreement with AWS allows AWS to terminate the agreement with two years' written notice and allows AWS, under certain circumstances, to temporarily restrict access to hosting services provided by AWS without prior notice. Although we expect that we could receive similar services from other third parties, if any of our arrangements with third parties, including AWS, are terminated, we could experience interruptions on our platform and in our ability to make our platform available to customers, as well as downtime, delays and additional expenses in arranging alternative cloud infrastructure services.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">It is possible that our customers and potential customers would hold us accountable for any breach of security affecting third parties&#8217; infrastructure. We may incur significant liability from those customers and from third parties with respect to any such breach. Because our agreement with AWS limits their liability for damages, we may not be able to recover a material portion of our liabilities to our customers and third parties from AWS in the event of any breach affecting AWS systems.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">If we continue to grow, we may not be able to manage our growth effectively.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We have recently experienced a period of rapid growth in our headcount and operations. In particular, we grew from 984 employees as of December 31, 2017 to 1,314 employees as of </span><span style="font-family:Arial;font-size:10pt;">June 30, 2019</span><span style="font-family:Arial;font-size:10pt;">. We have also significantly increased the size of our customer base over the last several years. We anticipate that we will continue to significantly expand our operations and headcount in the near term. Our growth has placed, and future growth will place, a significant strain on our management, administrative, operational and financial infrastructure. Our success will depend in part on our ability to manage this growth effectively. To manage the expected growth of our operations and personnel, we will need to continue to improve our operational, financial and management controls and our reporting systems and procedures. Failure to effectively manage our growth could result in difficulty or delays in deploying our solutions and services to customers, declines in quality or customer satisfaction, increases in costs, difficulties in introducing new features or other operational difficulties. Any of these difficulties could adversely impact our business performance and results of operations.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our rapid growth also makes it difficult to evaluate our future prospects. Our ability to forecast our future operating results is subject to a number of uncertainties, including our ability to plan for and model future growth. If our assumptions regarding these uncertainties, which we use to plan our business, are incorrect or change in reaction to changes in our markets, or if we do not address these risks successfully, our operating and financial results could differ materially from our expectations, our business could suffer and the trading price of our stock may decline.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Organizations may be reluctant to purchase our enterprise platform offerings that are cloud-based due to the actual or perceived vulnerability of cloud solutions.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Some organizations, including those in the defense industry and highly regulated industries such as healthcare and financial services, have historically been reluctant to use cloud-based solutions for cybersecurity because they have concerns regarding the risks associated with the reliability or security of the technology delivery model associated with these solutions. If we or other software companies with cloud-based offerings experience security incidents, breaches of customer data, disruptions in service delivery or other problems, the market for cloud-based solutions as a whole may be negatively impacted, which in turn would negatively impact our revenue and our growth prospects.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Our sales cycle is long and unpredictable.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The timing of sales of our offerings is difficult to forecast because of the length and unpredictability of our sales cycle, particularly with large enterprises and with respect to certain of our solutions. We sell our solutions primarily to IT departments that are managing a growing set of user and compliance demands, which has increased the complexity of customer requirements to be met and confirmed during the sales cycle and prolonged our sales cycle. Our average sales cycle with an enterprise customer is approximately four months. Further, the length of time that potential customers devote to their testing and evaluation, contract negotiation and budgeting processes varies significantly, depending on the size of the organization and nature of the product or service under consideration. In addition, we might devote substantial time and effort to a particular unsuccessful sales effort, and as a result, we could lose other sales opportunities or incur expenses that are not offset by an increase in revenue, which could harm our business.</span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">44</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Regulatory, legislative or self-regulatory standard developments regarding privacy and data security matters could adversely affect our ability to conduct our business. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We, along with a significant number of our customers, are subject to laws, rules, regulations and industry standards related to data privacy and cyber security, and restrictions or technological requirements regarding the collection, use, storage, protection, retention or transfer of data. In addition to current privacy and data security regulations currently in force in the jurisdictions where we operate, the General Data Protection Regulation, or GDPR came into force in May 2018. The GDPR contains numerous requirements and changes from prior European Union, or EU, law, including more robust obligations on data processors and data controllers, greater rights for data subjects, and heavier documentation requirements for data protection compliance programs. Specifically, the GDPR introduced numerous privacy-related changes for companies operating in the EU, including greater control over personal data by data subjects, such as the &#8220;right to be forgotten", increased data portability for EU consumers, data breach notification requirements, and increased fines. In particular, under the GDPR, fines of up to &#8364;20 million or up to 4% of the annual global revenue of the noncompliant company, whichever is greater, could be imposed for violations of certain of the GDPR&#8217;s requirements. The GDPR requirements apply not only to third-party transactions, but also to transfers of information between us and our subsidiaries, including employee information. We have an internal data privacy function that oversees and supervises our compliance with European data protection regulations. In the United States and globally, governments and agencies have adopted, and could in the future adopt, modify, apply or enforce laws, policies, regulations, and standards covering data subject privacy, data security, technologies such as cookies that are used to collect, store and/or process data, marketing online, the use of data to inform marketing, the taxation of products and services, unfair and deceptive practices and the collection, including the collection of information, use, processing, transfer, storage and/or disclosure of data associated with unique individual internet users. We may be subject directly or via contract to such laws, policies, regulations, and standards. New regulation or legislative actions regarding data privacy and security, together with applicable industry standards, may increase the costs of doing business and could have a material adverse impact on our operations and cash flows. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">While we have taken steps to mitigate the impact on us, such as implementing standard contractual clauses as appropriate and self-certifying under the EU-US Privacy Shield, the efficacy and longevity of these mechanisms remains uncertain. Potential or actual legal proceeding could lead to one or both of these mechanisms being declared invalid. Further, local data protection authorities general may have different interpretations of the GDPR, leading to potential inconsistencies amongst various EU states.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Similarly, there are a number of federal and state level legislative proposals in the United States that could impose new obligations on us. For example, California recently enacted the California Consumer Privacy Act, or the CCPA, which creates new individual privacy rights for consumers and places increased privacy and security obligations on entities handling the personal data of consumers or households. When it goes into effect on January 1, 2020, the CCPA will require covered companies to provide new disclosures to California consumers, which could include certain of our employees based on the broad definitions in the law, to provide such consumers new ways to opt out of certain sales of personal information and to allow for a new causes of action for data breaches.

Any such investigation or charges by applicable data protection authorities could have a negative effect on our existing business and on our ability to attract and retain new customers. Existing and proposed laws and regulations can be costly to comply with, could expose us to significant penalties for non-compliance, can delay or impede the development or adoption of our products and services, reduce the overall demand for our services, result in negative publicity, increase our operating costs, require significant management time and attention and subject us to claims or other remedies, including fines or demands that we modify or cease existing business practices.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">We rely on our third-party channel partner network of distributors and resellers to generate a substantial amount of our revenue.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our success is dependent in part upon establishing and maintaining relationships with a variety of channel partners that we utilize to extend our geographic reach and market penetration.

Our agreements with our channel partners, including our agreement with Ingram Micro, are non-exclusive and do not prohibit them from working with our competitors or offering competing solutions, and some of our channel partners may have more established relationships with our competitors. Similarly, our channel partners have no obligations to renew their agreements with us on commercially reasonable terms or at all, and certain of the agreements governing these relationships may be terminated by either party at any time, with no or limited notice. For example, our agreement with Ingram Micro allows Ingram Micro to terminate the agreement in their discretion upon 30 days&#8217; written notice to us. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">If our channel partners choose to place greater emphasis on products of their own or those offered by our competitors or a result of an acquisition, competitive factors or other reasons do not continue to market and sell our solutions in an effective manner or at all, our ability to grow our business and sell our solutions, particularly in key international markets, may be adversely affected. In addition, our failure to recruit additional channel partners, or any reduction or delay in their sales of our solutions and professional services or conflicts between channel sales and our direct sales and marketing activities may harm our results of operations. Finally, even if we are successful, our relationships with channel partners may not result in greater customer usage of our solutions and professional services or increased revenue.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">A portion of our revenue is generated from subscriptions and perpetual licenses sold to domestic governmental entities, foreign governmental entities and other heavily regulated organizations, which are subject to a number of challenges and risks.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">A portion of our revenue is generated from subscriptions and perpetual licenses sold to governmental entities in the United States. Additionally, many of our current and prospective customers, such as those in the financial services, energy, insurance and healthcare industries, are highly regulated and may be required to comply with more stringent regulations in connection with subscribing to and implementing our enterprise platform. Selling licenses to these entities can be highly competitive, expensive and time-consuming, often requiring significant upfront time and expense without any assurance that we will successfully complete a sale. Governmental demand and payment for our enterprise platform may also be impacted by public sector budgetary cycles and funding authorizations, with funding reductions or delays adversely affecting public sector demand for our enterprise platform. In addition, governmental entities have the authority to terminate contracts at any time for the convenience of the government, which creates risk regarding revenue anticipated under our existing government contracts.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Further, governmental and highly regulated entities often require contract terms that differ from our standard customer arrangements, including terms that can lead to those customers obtaining broader rights in our solutions than would be expected under a standard commercial contract and terms that can allow for early termination. The U.S. government will be able to terminate any of its contracts with us either for its convenience or if we default by failing to perform in accordance with the contract schedule and terms. Termination for convenience provisions would generally enable us to recover only our costs incurred or committed, settlement expenses, and profit on the work completed prior to termination. Termination for default provisions do not permit these recoveries and would make us liable for excess costs incurred by the U.S. government in procuring undelivered items from another source. Contracts with governmental and highly regulated entities may also include preferential pricing terms. In the United States, federal government agencies may promulgate regulations, and the President may issue executive orders, requiring federal contractors to adhere to different or additional requirements after a contract is signed. If we do not meet applicable requirements of law or contract, we could be subject to significant liability from our customers or regulators. Even if we do meet these requirements, the additional costs associated with providing our enterprise platform to government and highly regulated customers could harm our operating results. Moreover, changes in the underlying statutory and regulatory conditions that affect these types of customers could harm our ability to efficiently provide them access to our enterprise platform and to grow or maintain our customer base. In addition, engaging in sales activities to foreign governments introduces additional compliance risks, including risks specific to the U.S. Foreign Corrupt Practices Act of 1977, as amended, or the FCPA, the U.K. Bribery Act 2010 and other similar statutory requirements prohibiting bribery and corruption in the jurisdictions in which we operate.</span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">46</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Some of our revenue is derived from contracts with U.S. government entities, as well as subcontracts with higher-tier contractors. As a result, we are subject to federal contracting regulations, including the Federal Acquisition Regulation, or the FAR. Under the FAR, certain types of contracts require pricing that is based on estimated direct and indirect costs, which are subject to change.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In connection with our U.S. government contracts, we may be subject to government audits and review of our policies, procedures, and internal controls for compliance with contract terms, procurement regulations, and applicable laws. In certain circumstances, if we do not comply with the terms of a contract or with regulations or statutes, we could be subject to contract termination or downward contract price adjustments or refund obligations, could be assessed civil or criminal penalties, or could be debarred or suspended from obtaining future government contracts for a specified period of time. Any such termination, adjustment, sanction, debarment or suspension could have an adverse effect on our business.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In the course of providing our solutions and professional services to governmental entities, our employees and those of our channel partners may be exposed to sensitive government information. Any failure by us or our channel partners to safeguard and maintain the confidentiality of such information could subject us to liability and reputational harm, which could materially and adversely affect our results of operations and financial performance.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;padding-left:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">We may need to reduce our prices or change our pricing model to remain competitive.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Subscriptions and perpetual licenses to our enterprise platform are generally priced based on the number of IP addresses that can be monitored, or the total IT assets that can be monitored. We expect that we may need to change our pricing from time to time. As competitors introduce new products that compete with ours or reduce their prices, we may be unable to attract new customers or retain existing customers based on our historical pricing. We also must determine the appropriate price to enable us to compete effectively internationally. Moreover, mid- to large-size enterprises may demand substantial price discounts as part of the negotiation of sales contracts. As a result, we may be required or choose to reduce our prices or change our pricing model, which could adversely affect our business, operating results and financial condition.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Our pricing model subjects us to various challenges that could make it difficult for us to derive expected value from our customers.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our enterprise platform offerings are generally priced based on the number of IT assets or IP addresses that a customer chooses to monitor. As the amount of IT assets or IP addresses within our customers&#8217; organizations grows, we may face pressure from our customers regarding our pricing, which could adversely affect our revenue and operating margins.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our subscription agreements and perpetual licenses generally provide that we can audit our customers&#8217; use of our offerings to ensure compliance with the terms of such agreement or license and monitor an increase in IT assets and IP addresses being monitored. However, a customer may resist or refuse to allow us to audit their usage, in which case we may have to pursue legal recourse to enforce our rights under the agreement or license, which would require us to spend money, distract management and potentially adversely affect our relationship with our customers and users.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">If our enterprise platform offerings do not achieve sufficient market acceptance, our results of operations and competitive position will suffer.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We spend substantial amounts of time and money to research and develop and enhance our enterprise platform offerings to meet our customers&#8217; rapidly evolving demands. In addition, we invest in efforts to continue to add capabilities to our existing products and enable the continued detection of new network vulnerabilities. We typically incur expenses and expend resources upfront to market, promote and sell our new and enhanced offerings. Therefore, when we develop and introduce new or enhanced offerings, they must achieve high levels of market acceptance in order to justify the amount of our investment in developing and bringing them to market. For example, if Tenable.io does not garner widespread market adoption and implementation, our operating results and competitive position could suffer.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Further, we may make enhancements to our offerings that our customers do not like, find useful or agree with.

Our cloud offering enables our customers to eliminate the burden of provisioning and maintaining infrastructure and to scale their usage of our solutions quickly, while our on-premises offering allows for the customer&#8217;s complete control over data security and software infrastructure. Historically, our solutions were developed in the context of the on-premises offering, and we have less operating experience offering and selling subscriptions to our solutions via our cloud offering. Although a substantial majority of our revenue has historically been generated from customers using our solutions on an on-premises basis, our customers are increasingly adopting our cloud offering. We expect that our customers will continue to move to our cloud offering and that it will become more central to our distribution model. We expect our gross profit to increase in absolute dollars and our gross margin to decrease to the extent that revenue from our cloud-based subscriptions increases as a percentage of revenue, although our gross margin could fluctuate from period to period. To support both on-premises environments and cloud instances of our product, our support team must be trained on and learn multiple environments in which our solution is deployed, which is more expensive than supporting only a cloud offering. Moreover, we must engineer our software for an on-premises environment, cloud offering and hybrid installation, which we expect will cause us additional research and development expense that may impact our operating results. As more of our customers transition to the cloud, we may be subject to additional competitive pressures, which may harm our business. We are directing a significant portion of our financial and operating resources to implement a robust and secure cloud offering for our customers, but even if we continue to make these investments, we may be unsuccessful in growing or implementing our cloud offering in a way that competes successfully against our current and future competitors and our business, results of operations and financial condition could be harmed.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Our customers&#8217; increased usage of our cloud-based offerings requires us to continually improve our computer network and infrastructure to avoid service interruptions or slower system performance.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">As usage of our cloud-based offerings grows and as customers use them for more complicated applications, increased assets and with increased data requirements, we will need to devote additional resources to improving our platform architecture and our infrastructure in order to maintain the performance of our cloud offering. Any failure or delays in our computer systems could cause service interruptions or slower system performance. If sustained or repeated, these performance issues could reduce the attractiveness of our enterprise platform to customers. These performance issues could result in lost customer opportunities and lower renewal rates, any of which could hurt our revenue growth, customer loyalty and reputation.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">A component of our growth strategy is dependent on our continued international expansion, which adds complexity to our operations.</span></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We market and sell our solutions and professional services throughout the world and have personnel in many parts of the world.

Our failure, or the failure by our channel partners, to comply with these regulations could adversely affect our business. Further, in many foreign countries it is common for others to engage in business practices that are prohibited by our internal policies and procedures or U.S. regulations applicable to us. Although we have implemented policies and procedures designed to comply with these laws and policies, there can be no assurance that our employees, contractors, channel partners and agents have complied, or will comply, with these laws and policies. Violations of laws or key control policies by our employees, contractors, channel partners or agents could result in delays in revenue recognition, financial reporting misstatements, fines, penalties or the prohibition of the importation or exportation of our solutions and could have a material adverse effect on our business and results of operations.

We do not maintain key man insurance on any of our executive officers or key employees. From time to time, there may be changes in our senior management team resulting from the termination or departure of our executive officers and key employees. Our senior management and key employees are employed on an at-will basis, which means that they could terminate their employment with us at any time. The loss of any of our senior management or key employees could adversely affect our ability to build on the efforts they have undertaken and to execute our business plan, and we may not be able to find adequate replacements.

We plan to continue expanding our sales force and our third-party channel partner network of distributors and resellers both domestically and internationally; however, there is no assurance that we will be successful in attracting and retaining talented sales personnel or strategic partners or that any new sales personnel or strategic partners will be able to achieve productivity in a reasonable period of time or at all. We also plan to dedicate significant resources to sales and marketing programs, including through electronic marketing campaigns and trade event sponsorship and participation. All of these efforts will require us to invest significant financial and other resources and our business will be harmed if our efforts do not generate a correspondingly significant increase in revenue.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">We must offer high-quality support.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our customers rely on our personnel for support of our enterprise platform. High-quality support is important for the renewal of our agreements with existing customers and to our existing customers expanding the number of IP addresses or IT assets under their subscriptions. The importance of high-quality support will increase as we expand our business and pursue new customers. If we do not help our customers quickly resolve issues and provide effective ongoing support, our ability to sell new software to existing and new customers would suffer and our reputation with existing or potential customers would be harmed.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Our growth depends in part on the success of our strategic relationships with third parties.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In order to grow our business, we anticipate that we will continue to depend on relationships with strategic partners to provide broader customer coverage and solution delivery capabilities. We depend on partnerships with market leading technology companies to maintain and expand our Cyber Exposure ecosystem by integrating third party data into our platform. For example, we developed our Industrial Security solution in partnership with Siemens. Identifying partners, and negotiating and documenting relationships with them, requires significant time and resources. Our agreements with our strategic partners generally are non-exclusive and do not prohibit them from working with our competitors or offering competing solutions. Our competitors may be effective in providing incentives to third parties to favor their products or services or to prevent or reduce subscriptions to our services. If our partners choose to place greater emphasis on products of their own or those offered by our competitors or do not effectively market and sell our product, our ability to grow our business and sell software and professional services may be adversely affected. In addition, acquisitions of our partners by our competitors could result in a decrease in the number of our current and potential customers, as our partners may no longer facilitate the adoption of our solutions by potential customers.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">If we are unsuccessful in establishing or maintaining our relationships with third parties, our ability to compete in the marketplace or to grow our revenue could be impaired and our operating results may suffer.

In the event of a major hurricane, earthquake or catastrophic event such as fire, power loss, telecommunications failure, cyberattack, war or terrorist attack, we may be unable to continue our operations and may endure system interruptions, reputational harm, delays in our software development, lengthy interruptions in our services, breaches of data security and loss of critical data, all of which could have an adverse effect on our future operating results.</span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">50</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Future acquisitions could disrupt our business and adversely affect our business operations and financial results.</span></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We have in the past acquired products and technologies from other parties, and we may choose to expand our current business by acquiring additional businesses or technologies in the future.

However, we intend to continue to make investments to support our business growth and may require additional funds to respond to business challenges, including the need to develop new features or enhance our product, improve our operating infrastructure or acquire complementary businesses and technologies. Accordingly, we may need to engage in equity or debt financings to secure additional funds. If we raise additional funds through future issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. Our loan and security agreement with Silicon Valley Bank includes restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions, and any debt financing that we secure in the future could have similar restrictive covenants. We may not be able to obtain additional financing on terms favorable to us, if at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly impaired, and our business may be adversely affected.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">The nature of our business requires the application of complex accounting rules and regulations. Significant changes in current principles will affect our consolidated financial statements and changes in financial accounting standards or practices may cause adverse, unexpected financial reporting fluctuations and harm our results of operations.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The accounting rules and regulations that we must comply with are complex and subject to interpretation by the Financial Accounting Standards Board, or FASB, the Securities and Exchange Commission, or SEC, and various bodies formed to promulgate and interpret appropriate accounting principles.

Further, the accounting rules and regulations are continually changing in ways that could impact our financial statements.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">If our estimates or judgments relating to our critical accounting policies prove to be incorrect or financial reporting standards or interpretations change, our results of operations could be adversely affected.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The preparation of financial statements in conformity with generally accepted accounting principles in the United States, or U.S. GAAP, requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, as provided in &#8220;Management&#8217;s Discussion and Analysis of Financial Condition and Results of Operations.&#8221; The results of these estimates form the basis for making judgments about the carrying values of assets, liabilities and equity, and the amount of revenue and expenses that are not readily apparent from other sources. Significant assumptions and estimates used in preparing our consolidated financial statements include the determination of the estimated economic life of perpetual licenses for revenue recognition, the estimated period of benefit for deferred commissions,useful lives of long-lived assets, the valuation of stock-based compensation, including the estimated underlying fair value of our common stock prior to our IPO, the incremental borrowing rate for operating leases, and the valuation of deferred tax assets. Our results of operations may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our results of operations to fall below the expectations of securities analysts and investors, resulting in a decline in the trading price of our common stock.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Additionally, we regularly monitor our compliance with applicable financial reporting standards and review new pronouncements and drafts thereof that are relevant to us. As a result of new standards, changes to existing standards and changes in their interpretation, we might be required to change our accounting policies, alter our operational policies and implement new or enhance existing systems so that they reflect new or amended financial reporting standards, or we may be required to restate our published financial statements. Such changes to existing standards or changes in their interpretation may have an adverse effect on our reputation, business, financial position and profit, or cause an adverse deviation from our revenue and operating profit target, which may negatively impact our financial results.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Our operating results may be negatively affected if we are required to pay additional state sales tax, value added, or other transaction taxes, and we could be subject to liability with respect to all or a portion of past or future sales.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We currently collect and remit sales and use, value added and other transaction taxes in certain of the jurisdictions where we do business based on our assessment of the amount of taxes owed by us in such jurisdictions. However, in some jurisdictions in which we do business, we do not believe that we owe such taxes, and therefore we currently do not collect and remit such taxes in those jurisdictions or record contingent tax liabilities in respect of those jurisdictions.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Further, due to uncertainty in the application and interpretation of applicable tax laws in various jurisdictions, we may be exposed to sales and use, value added or other transaction tax liability. A successful assertion that we are required to pay additional taxes in connection with sales of our solutions, or the imposition of new laws or regulations requiring the payment of additional taxes, would create increased costs and administrative burdens for us. If we are subject to additional taxes and determine to offset such increased costs by collecting and remitting sales taxes from our customers, or otherwise passing those costs through to our customers, companies may be discouraged from using our solutions. Any increased tax burden may decrease our ability or willingness to compete in relatively burdensome tax jurisdictions, result in substantial tax liabilities related to past sales or otherwise harm our business and operating results.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Our ability to use net operating losses to offset future taxable income may be subject to certain limitations.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">As of December 31, 2018, we had federal, state, and foreign net operating loss carryforwards, or NOLs, of $85.9 million, $60.4 million, and $102.3 million, respectively, available to offset future taxable income, which begin to expire in 2030. A lack of future taxable income would adversely affect our ability to utilize these NOLs before they expire.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In addition, under the provisions of the Internal Revenue Code of 1986, as amended, or the Internal Revenue Code, substantial changes in our ownership may limit the amount of pre-change NOLs that can be utilized annually in the future to offset taxable income. Section 382 of the Internal Revenue Code imposes limitations on a company&#8217;s </span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">52</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">ability to use NOLs if a company experiences a more-than-50-percent ownership change over a three-year testing period. Based upon an analysis as of December 31, 2017, we determined that we do not expect these limitations to impair our ability to use our NOLs prior to expiration. However, if changes in our ownership occur in the future, our ability to use our NOLs may be further limited. For these reasons, we may not be able to utilize a material portion of the NOLs, even if we achieve profitability.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Uncertainties in the interpretation and application of the 2017 Tax Cuts and Jobs Act could materially affect our tax obligations and effective tax rate.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Forecasts of our income tax position and effective tax rate for financial accounting purposes are complex and subject to uncertainty because our income tax position for each year combines the effects of a mix of profits earned and losses incurred by us in various tax jurisdictions with a broad range of income tax rates, as well as changes in the valuation of deferred tax assets and liabilities, the impact of various accounting rules and changes to these rules and tax laws, the results of examinations by various tax authorities, and the impact of any acquisition, business combination or other reorganization or financing transaction. To forecast our global tax rate, we estimate our pre-tax profits and losses by jurisdiction and forecast our tax expense by jurisdiction. If the mix of profits and losses, our ability to use tax credits, our assessment of the need for valuation allowances, or effective tax rates by jurisdiction is different than those estimated, our actual tax rate could be materially different than forecasted, which could have a material impact on our results of business, financial condition and results of operations.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">On December 22, 2017, U.S. Federal tax reform was enacted with the signing of the Tax Cuts and Jobs Act, or TCJA. Notable provisions of the TCJA included significant changes to corporate taxation, including reduction of the corporate tax rate from a top marginal rate of 35% to a flat rate of 21%, limitation of the tax deduction for interest expense to 30% of adjusted earnings (except for certain small businesses), limitation of the deduction for net operating losses to 80% of current year taxable income and elimination of net operating loss carrybacks, one time taxation of offshore earnings at reduced rates regardless of whether they are repatriated, elimination of U.S. tax on foreign earnings (subject to certain important exceptions), immediate deductions for certain new investments instead of deductions for depreciation expense over time, and modifying or repealing many business deductions and credits. We continue to examine the impact that the TCJA may have on our business. The impact of this tax reform on us and on holders of our common stock is uncertain and could materially impact our financial results.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">We are subject to anti-corruption laws, anti-bribery and similar laws with respect to our domestic and international operations, and non-compliance with such laws can subject us to criminal and/or civil liability and materially harm our business and reputation.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We are subject to the FCPA, the U.S. domestic bribery statute contained in 18 U.S.C. &#167; 201, the U.S. Travel Act, the U.K. Bribery Act 2010, and other anti-corruption laws in countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit our company from authorizing, offering, or providing, directly or indirectly, improper payments or benefits to recipients in the public or private sector. We use third-party law firms, accountants, and other representatives for regulatory compliance, sales, and other purposes in several countries. We sell directly and indirectly, via third-party representatives, to the U.S. and non-U.S. government sectors, and our employees and third-party representatives interact with government officials. We can be held liable for the corrupt or other illegal activities of these third-party representatives, our employees, contractors, and other agents, even if we do not explicitly authorize such activities. Noncompliance with these laws could subject us to whistleblower complaints, investigations, sanctions, settlements, prosecution, other enforcement actions, disgorgement of profits, significant fines, damages, other civil and criminal penalties or injunctions, suspension and/or debarment from contracting with certain persons, the loss of export privileges, reputational harm, adverse media coverage, and other collateral consequences. If any subpoenas or investigations are launched, or governmental or other sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our reputation, business, results of operations and financial condition could be materially harmed. In addition, responding to any action will likely result in a materially significant diversion of management&#8217;s attention and resources and significant defense costs and other professional fees. Enforcement actions and sanctions could further harm our business, results of operations, and financial condition. Moreover, as an issuer of securities, we also are subject to the accounting and internal controls provisions of the FCPA. These provisions require us to maintain accurate books and records and a system of internal controls sufficient to detect and prevent corrupt conduct. Failure to abide by these provisions may have an adverse effect on our business, operations or financial condition.</span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">53</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">We are subject to governmental export and import controls and economic and trade sanctions that could impair our ability to conduct business in international markets and subject us to liability if we are not in compliance with applicable laws and regulations.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The United States and other countries maintain and administer export and import laws and regulations. Our products are subject to U.S. export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations, and various economic and trade sanctions administered by the U.S. Treasury Department&#8217;s Office of Foreign Assets Control. We are required to comply with these laws and regulations. If we fail to comply with such laws and regulations, we and certain of our employees could be subject to substantial civil or criminal penalties, including the possible loss of export or import privileges; fines, which may be imposed on us and responsible employees or managers; and, in extreme cases, the incarceration of responsible employees or managers. Obtaining the necessary authorizations, including any required license, for a particular sale may be time-consuming, is not guaranteed and may result in the delay or loss of sales opportunities. In addition, changes in our solutions, or changes in applicable export or import laws and regulations may create delays in the introduction and sale of our products in international markets or, in some cases, prevent the export or import of our solutions to certain countries, governments or persons altogether. Any change in export or import laws and regulations or economic or trade sanctions, shift in the enforcement or scope of existing laws and regulations, or change in the countries, governments, persons or technologies targeted by such laws and regulations could also result in decreased use of our products, or in our decreased ability to export or sell our products to existing or potential customers. Any decreased use of our products or limitation on our ability to export or sell our products would likely adversely affect our business, financial condition, and results of operations.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Furthermore, we incorporate encryption technology into certain of our solutions. Various countries regulate the import of certain encryption technology, including import permitting and licensing requirements, and have enacted laws that could limit our ability to distribute our solutions or could limit our customers&#8217; ability to implement our solutions in those countries. Encrypted products and the underlying technology may also be subject to export control restrictions. Governmental regulation of encryption technology and regulation of imports or exports of encryption solutions, or our failure to obtain required import or export approval for our solutions, could harm our international sales and adversely affect our revenue. Compliance with applicable laws and regulations regarding the export and import of our solutions, including with respect to new solutions or changes in existing solutions, may create delays in the introduction of our solutions in international markets, prevent our customers with international operations from deploying our solutions globally or, in some cases, could prevent the export or import of our solutions to certain countries, governments, entities or persons altogether.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Moreover, U.S. export control laws and economic sanctions programs prohibit the shipment of certain products and services to countries, governments and persons that are subject to U.S. economic embargoes and trade sanctions. Any violations of such economic embargoes and trade sanction regulations could have negative consequences, including government investigations, penalties and reputational harm.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-weight:bold;">Risks Related to Government Regulation, Data Collection and Intellectual Property</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Our business could be adversely affected if our employees cannot obtain and maintain required security clearances or we cannot establish and maintain a required facility security clearance.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Certain U.S. government contracts may require our employees to maintain various levels of security clearances, and may require us to maintain a facility security clearance, to comply with Department of Defense, or DoD, requirements. The DoD has strict security clearance requirements for personnel who perform work in support of classified programs. Obtaining and maintaining security clearances for employees involves a lengthy process, and it is difficult to identify, recruit and retain employees who already hold security clearances. If our employees are unable to obtain security clearances in a timely manner, or at all, or if our employees who hold security clearances are unable to maintain their clearances or terminate employment with us, then a customer requiring classified work could terminate an existing contract or decide not to renew the contract upon its expiration. To the extent we are not able to obtain or maintain a facility security clearance, we may not be able to bid on or win new classified contracts, and existing contracts requiring a facility security clearance could be terminated.</span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">54</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Any failure to protect our proprietary technology and intellectual property rights could substantially harm our business and operating results.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our success and ability to compete depend in part on our ability to protect our proprietary technology and intellectual property. To safeguard these rights, we rely on a combination of patent, trademark, copyright and trade secret laws and contractual protections in the United States and other jurisdictions, all of which provide only limited protection and may not now or in the future provide us with a competitive advantage.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">As of </span><span style="font-family:Arial;font-size:10pt;">June 30, 2019</span><span style="font-family:Arial;font-size:10pt;">, we had 15 issued patents and seven patent applications pending in the United States relating to our technology. We cannot assure you that any patents will issue from any patent applications, that patents that issue from such applications will give us the protection that we seek or that any such patents will not be challenged, invalidated or circumvented. Any patents that may issue in the future from our pending or future patent applications may not provide sufficiently broad protection and may not be enforceable in actions against alleged infringers. Obtaining and enforcing software patents in the United States is becoming increasingly challenging. Any patents we have obtained or may obtain in the future may be found to be invalid or unenforceable in light of recent and future changes in the law. We have registered the &#8220;Tenable,&#8221; &#8220;Nessus&#8221; and &#8220;Tenable.io&#8221; names and our Tenable logo in the United States and certain other countries. We have registrations and/or pending applications for additional marks in the United States; however, we cannot assure you that any future trademark registrations will be issued for pending or future applications or that any registered trademarks will be enforceable or provide adequate protection of our proprietary rights. While we have copyrights in our software we do not typically register such copyrights with the Copyright Office. This failure to register the copyrights in our software may preclude us from obtaining statutory damages for infringement under certain circumstances. We also license software from third parties for integration into our software, including open source software and other software available on commercially reasonable terms. We cannot assure you that such third parties will maintain such software or continue to make it available.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In order to protect our unpatented proprietary technologies and processes, we rely on trade secret laws and confidentiality and invention assignment agreements with our employees, consultants, strategic partners, vendors and others. Despite our efforts to protect our proprietary technology and trade secrets, unauthorized parties may attempt to misappropriate, copy, reverse engineer or otherwise obtain and use them. In addition, others may independently discover our trade secrets, in which case we would not be able to assert trade secret rights, or develop similar technologies and processes. Further, several agreements may give customers limited rights to access portions of our proprietary source code, and the contractual provisions that we enter into may not prevent unauthorized use or disclosure of our proprietary technology or intellectual property rights and may not provide an adequate remedy in the event of unauthorized use or disclosure of our proprietary technology or intellectual property rights. Moreover, policing unauthorized use of our technologies, trade secrets and intellectual property is difficult, expensive and time-consuming, particularly in foreign countries where the laws may not be as protective of intellectual property rights as those in the United States and where mechanisms for enforcement of intellectual property rights may be weak. To the extent that we expand our activities outside of the United States, our exposure to unauthorized copying and use of our solutions and proprietary information may increase. We may be unable to determine the extent of any unauthorized use or infringement of our solutions, technologies or intellectual property rights.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">There can be no assurance that the steps that we take will be adequate to protect our proprietary technology and intellectual property, that others will not develop or patent similar or superior technologies, solutions or services, or that our trademarks, patents, and other intellectual property will not be challenged, invalidated or circumvented by others. Furthermore, effective trademark, patent, copyright, and trade secret protection may not be available in every country in which our software is available or where we have employees or independent contractors. In addition, the legal standards relating to the validity, enforceability, and scope of protection of intellectual property rights in internet and software-related industries are uncertain and still evolving.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In order to protect our intellectual property rights, we may be required to spend significant resources to monitor and protect these rights. Litigation brought to protect and enforce our intellectual property rights could be costly, time-consuming and distracting to management and could result in the impairment or loss of portions of our intellectual property. Furthermore, our efforts to enforce our intellectual property rights may be met with defenses, counterclaims and countersuits attacking the validity and enforceability of our intellectual property rights. Our failure to secure, protect and enforce our intellectual property rights could seriously adversely affect our brand and adversely impact our business.</span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">55</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">We may be subject to intellectual property rights claims by third parties, which are extremely costly to defend, could require us to pay significant damages and could limit our ability to use certain technologies.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Companies in the software and technology industries, including some of our current and potential competitors, own significant numbers of patents, copyrights, trademarks and trade secrets and frequently enter into litigation based on allegations of infringement or other violations of intellectual property rights. In addition, many of these companies have the capability to dedicate substantially greater resources to enforce their intellectual property rights and to defend claims that may be brought against them. The litigation may involve patent holding companies or other adverse patent owners that have no relevant product revenue and against which our patents may therefore provide little or no deterrence. In the past, we have been subject to allegations of patent infringement that were unsuccessful, and we expect in the future to be subject to claims that we have misappropriated, misused, or infringed other parties&#8217; intellectual property rights, and, to the extent we gain greater market visibility or face increasing competition, we face a higher risk of being the subject of intellectual property infringement claims, which is not uncommon with respect to enterprise software companies. We may in the future be subject to claims that employees or contractors, or we, have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of our competitors or other parties. To the extent that intellectual property claims are made against our customers based on their usage of our technology, we have certain obligations to indemnify and defend such customers from those claims. The term of our contractual indemnity provisions often survives termination or expiration of the applicable agreement. Large indemnity payments, defense costs or damage claims from contractual breach could harm our business, results of operations and financial condition.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">There may be third-party intellectual property rights, including issued or pending patents that cover significant aspects of our technologies or business methods. Any intellectual property claims, with or without merit, could be very time-consuming, could be expensive to settle or litigate, could divert our management&#8217;s attention and other resources and could result in adverse publicity. These claims could also subject us to making substantial payments for legal fees, settlement payments, and other costs or damages, potentially including treble damages if we are found to have willfully infringed patents or copyrights. These claims could also result in our having to stop making, selling, offering for sale, or using technology found to be in violation of a third party&#8217;s rights. We might be required to seek a license for the third-party intellectual property rights, which may not be available on reasonable terms or at all. Even if a license is available to us, we may be required to pay significant upfront fees, milestones or royalties, which would increase our operating expenses. Moreover, to the extent we only have a license to any intellectual property used in our solutions, there may be no guarantee of continued access to such intellectual property, including on reasonable terms. As a result, we may be required to develop alternative non-infringing technology, which could require significant effort and expense. If a third party is able to obtain an injunction preventing us from accessing such third-party intellectual property rights, or if we cannot license or develop technology for any infringing aspect of our business, we would be forced to limit or stop sales of our software or cease business activities covered by such intellectual property, and may be unable to compete effectively. Any of these results would adversely affect our business, results of operations, financial condition and cash flows.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Portions of our solutions utilize open source software, and any failure to comply with the terms of one or more of these open source licenses could negatively affect our business.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our software contains software made available by third parties under so-called &#8220;open source&#8221; licenses. From time to time, there have been claims against companies that distribute or use open source software in their products and services, asserting that such open source software infringes the claimants&#8217; intellectual property rights. We could be subject to suits by parties claiming that what we believe to be licensed open source software infringes their intellectual property rights. Use and distribution of open source software may entail greater risks than use of third-party commercial software, as open source licensors generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. In addition, certain open source licenses require that source code for software programs that are subject to the license be made available to the public and that any modifications or derivative works to such open source software continue to be licensed under the same terms. Further, certain open source licenses also include a provision that if we enforce any patents against the software programs that are subject to the license, we would lose the license to such software. If we were to fail to comply with the terms of such open source software licenses, such failures could result in costly litigation, lead to negative public relations or require that we quickly find replacement software which may be difficult to accomplish in a timely manner.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Although we monitor our use of open source software in an effort both to comply with the terms of the applicable open source licenses and to avoid subjecting our software to conditions we do not intend, the terms of many open source licenses have not been interpreted by U.S. courts, and there is a risk that these licenses could be construed in </span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">56</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">a way that could impose unanticipated conditions or restrictions on our ability to commercialize our product or operate our business. By the terms of certain open source licenses, we could be required to release the source code of our software and to make our proprietary software available under open source licenses, if we combine or distribute our software with open source software in a certain manner. In the event that portions of our software are determined to be subject to an open source license, we could be required to publicly release the affected portions of our source code, re-engineer all, or a portion of, that software or otherwise be limited in the licensing of our software, each of which could reduce or eliminate the value of our product.

These fluctuations have often been unrelated or disproportionate to the operating performance of those companies. Broad market and industry fluctuations, as well as general economic, political, regulatory and market conditions, may negatively impact the market price of our common stock.

We do not control these analysts or the content and opinions included in their reports. As a new public company, we may be slow to attract research coverage and the analysts who publish information about our common stock will have had relatively little experience with our company, which could affect their ability to accurately forecast our results and make it more likely that we fail to meet their estimates. If our financial performance fails to meet analyst estimates or one or more of the analysts who cover us downgrade our shares or change their opinion of our shares, our share price would likely decline. In addition, the stock prices of many companies in the technology industry have declined significantly after those companies have failed to meet, or significantly exceed, the financial guidance publicly announced by the companies or the expectations of analysts. If our financial results fail to meet, or exceed, our announced guidance or the expectations of analysts or public investors, analysts could downgrade our common stock or publish unfavorable research about us. If one or more of these analysts cease coverage of our company or fail to regularly publish reports on us, we could lose visibility in the financial markets, which could cause our share price or trading volume to decline.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Future sales of substantial amounts of our common stock in the public markets, or the perception that they might occur, could reduce the price that our common stock might otherwise attain.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Sales of a substantial number of shares of our common stock in the public market by us or our stockholders, or the perception that these sales might occur, including in connection with anticipated distributions of shares of our common stock by entities affiliated with members of our Board of Directors, could depress the market price of our common stock, impair our ability to raise capital through the sale of additional equity securities and make it more difficult for you to sell your common stock at a time and price that you deem appropriate. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Upon the closing of our IPO, the 12,535,000 shares sold in the offering became freely tradable, and all the remaining shares of common stock outstanding at the time of our IPO became available for sale in the public market in January 2019 following the expiration of lock-up agreements between our stockholders and the underwriters for the IPO. Additionally, stockholders holding a substantial majority of the outstanding shares of our common stock have the right, subject to various conditions and limitations, to require us to file one or more registration statements covering their shares or to include their shares of our common stock in registration statements that we may file for ourselves or other stockholders. If the offer and sale of these shares are registered, they will be freely tradable without restriction under the Securities Act. Shares of common stock sold under such registration statements can be freely sold in the public market. In the event such registration rights are exercised and a large number of shares of common stock are sold in the public market, such sales could reduce the trading price of our common stock.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In addition, we filed a registration statement on Form S-8 under the Securities Act registering the issuance of shares of common stock subject to options or other equity awards issued or reserved for future issuance under our equity incentive plans.

Compliance with these rules and regulations increases our legal and financial compliance costs, makes some activities more difficult, time-consuming or costly and increases demand on our systems and resources, particularly after we cease to be an emerging growth company on December 31, 2019. Among other things, the Exchange Act requires that we file annual, quarterly and current reports with respect to our business and results of operations and maintain effective disclosure controls and procedures and internal control over financial reporting. In order to improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight may be required. As a result, management&#8217;s attention may be diverted from other business concerns, which could harm our business, financial condition, results of operations and prospects. Although we have already hired, and are in the process of hiring, additional personnel to help comply with these requirements, we may need to further expand our legal and finance departments in the future, which will increase our costs and expenses.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In addition, changing laws, regulations and standards relating to corporate governance and public disclosure are creating uncertainty for public companies, increasing legal and financial compliance costs and making some activities more time-consuming. These laws, regulations and standards are subject to varying interpretations, in many cases due to their lack of specificity, and, as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies. This could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We intend to invest resources to comply with evolving laws, regulations and standards, and this investment may result in increased general and administrative expense and a diversion of management&#8217;s time and attention from revenue-generating activities to compliance activities. If our efforts to comply with new laws, regulations and standards differ from the activities intended by regulatory or governing bodies, regulatory authorities may initiate legal proceedings against us and our business and prospects may be harmed. As a result of disclosure of information in the filings required of a public company, our business and financial condition will become more visible, which may result in threatened or actual litigation, including by competitors and other third parties. If such claims are successful, our business, financial condition, results of operations and prospects could be materially harmed, and even if the claims do not result in litigation or are resolved in our favor, these claims, and the time and resources necessary to resolve them, could divert the resources of our management and materially harm our business, financial condition, results of operations and prospects.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We also expect that being a public company and these new rules and regulations will make it more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could also make it more difficult for us to attract and retain qualified executive officers and members of our Board of Directors, particularly to serve on our audit committee and compensation committee.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In addition, as a result of our disclosure obligations as a public company, we may have reduced strategic flexibility and may be under pressure to focus on short-term results, which could materially and adversely affect our ability to achieve long-term profitability.</span></div><div><br/></div><div style="text-align:center;"><div style="line-height:120%;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">59</span></div></div><hr style="page-break-after:always"></hr><div><div style="line-height:120%;padding-left:18px;text-indent:0px;font-size:10pt;"><a style="font-family:Arial;font-size:10pt;" href="#s25BB0FDD20885EBBACB24D7393C64C8E"><span style="font-family:Arial;font-size:10pt;">Table of Contents</span></a></div></div><div><br/></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">We do not intend to pay dividends for the foreseeable future and, as a result, your ability to achieve a return on your investment will depend on appreciation in the price of our common stock.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We have never declared or paid any cash dividends on our common stock and do not intend to pay any cash dividends in the foreseeable future. We anticipate that we will retain all of our future earnings for use in the development of our business and for general corporate purposes. Any determination to pay dividends in the future will be at the discretion of our Board of Directors. Accordingly, investors must rely on sales of their common stock after price appreciation, which may never occur, as the only way to realize any future gains on their investments. In addition, our loan and security agreement with Silicon Valley Bank contains restrictive covenants that prohibit us, subject to certain exceptions, from paying dividends on our common stock.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">As a result of being a public company, we are obligated to develop and maintain proper and effective internal controls over financial reporting, and any failure to maintain the adequacy of these internal controls may adversely affect investor confidence in our company and, as a result, the value of our common stock.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We will be required, pursuant to Section 404 of the Sarbanes-Oxley Act, or Section 404, to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting in our annual report for the year ending December 31, 2019 to be filed with the SEC in 2020. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting. In addition, our independent registered public accounting firm will be required to attest to the effectiveness of our internal control over financial reporting in that annual report. We are also required to disclose significant changes made in our internal control procedures on a quarterly basis.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We have commenced the costly and challenging process of compiling the system and processing documentation necessary to perform the evaluation needed to comply with Section 404, and we may not be able to complete our evaluation, testing and any required remediation in a timely fashion. Our compliance with Section 404 will require that we incur substantial professional fees and expend significant management efforts, and we may need to hire additional accounting and financial staff with appropriate public company experience and technical accounting knowledge and compile the system and process documentation necessary to perform the evaluation needed to comply with Section 404.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">During the evaluation and testing process of our internal controls, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert that our internal control over financial reporting is effective. We cannot assure you that there will not be material weaknesses or significant deficiencies in our internal control over financial reporting in the future. Any failure to maintain internal control over financial reporting could severely inhibit our ability to accurately report our financial condition or results of operations. If we are unable to conclude that our internal control over financial reporting is effective, or if our independent registered public accounting firm determines we have a material weakness or significant deficiency in our internal control over financial reporting, we could lose investor confidence in the accuracy and completeness of our financial reports, the market price of our common stock could decline, and we could be subject to sanctions or investigations by the Nasdaq, the SEC or other regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting, or to implement or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us more difficult, limit attempts by our stockholders to replace or remove members of our Board of Directors and our current management and could negatively impact the market price of our common stock.</span></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could delay or prevent a change in control of our company.

In addition, (i) if you remain in Continuous Service through the closing of a Change in Control and your unvested Restricted Stock Units upon the closing of the Change in Control are not continued, assumed or substituted for as permitted by Section 9(c) of the Plan in connection with a Change in Control, or if your Continuous Service terminates due to an involuntary termination by the Company without Cause or your required resignation at the request of the acquiring or successor entity in connection with the Change in Control at any time between the date a definitive agreement providing for a Change in Control is entered into and on or before the closing of a Change in Control (provided that such Change in Control closes and becomes effective (and the Common Stock underlying your Restricted Stock Units is issued) by no later than March 15 of the calendar year immediately following the calendar year in which the definitive agreement is entered into), then the remaining unvested Restricted Stock Units will become fully vested as of the closing of the Change in Control, or (ii) if your unvested Restricted Stock Units are continued, assumed or substituted for as permitted by Section 9(c) of the Plan in connection with a Change in Control and if at any time between the closing of a Change in Control and the date which is twelve (12) months after the closing of such Change in Control, your Continuous Service terminates due to an involuntary termination by the Company without Cause or your required resignation at the request of the acquiring or successor entity in connection with the Change in Control, then the remaining unvested Restricted Stock Units at that time will accelerate and be deemed to be vested in full upon such termination of Continuous Service.  Furthermore, any remaining unvested Restricted Stock Units will vest in full upon the termination of your Continuous Service due to your death or Disability.  In addition, notwithstanding the foregoing, the Restricted Stock Units shall be subject to the terms of any other written agreement entered into between the Company or any Affiliate of the Company and you regarding additional accelerated vesting in connection with certain terminations of service and/or transactions involving the Company or any Affiliate of the Company.  </font></div><div><br></div><div></div><hr style="page-break-after:always"><div></div><div><br></div><div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:48px;font-size:10pt;"><font style="font-family:Arial;font-size:10pt;">For this purpose, &#8220;</font><font style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Cause</font><font style="font-family:Arial;font-size:10pt;">&#8221; shall have the meaning ascribed to such term in the Plan; provided, however, that if you have entered into any other written agreement with the Company or any of its Affiliates defining such term, the term &#8220;Cause&#8221; shall have the meaning set forth in such other written agreement. </font></div><div style="line-height:120%;padding-left:0px;padding-bottom:16px;text-align:justify;text-indent:48px;"><font style="padding-bottom:16px;text-align:justify;font-family:Arial;font-size:10pt;font-weight:bold;padding-right:48px;">3.</font><font style="font-family:Arial;font-size:10pt;font-weight:bold;">NUMBER OF SHARES.  </font><font style="font-family:Arial;font-size:10pt;">The number of Restricted Stock Units subject to your Award may be adjusted from time to time for Capitalization Adjustments, as provided in the Plan.

These estimates include, but are not limited to, the determination of the estimated economic life of perpetual licenses for revenue recognition, the estimated period of benefit for deferred commissions, useful lives of long-lived assets, the valuation of stock-based compensation, including the estimated underlying fair value of our common stock prior to our IPO, the incremental borrowing rate for operating leases, and the valuation of deferred tax assets. We base these estimates on historical experience and on various other assumptions that we believe to be reasonable. Actual results could differ significantly from these estimates.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;"&gt;Revenue Recognition&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;We recognize revenue in order to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services.

style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Subscription Revenue&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Subscription arrangements generally have annual or multi-year contractual terms for the use of our software or cloud solutions, including ongoing software updates and the ability to identify the latest cybersecurity vulnerabilities. Revenue is recognized ratably over the subscription term given the critical utility provided by the ongoing updates that are released throughout the contract period. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Perpetual License and Maintenance Revenue &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Our perpetual licenses are generally sold with one or more years of maintenance, which include ongoing software updates and the ongoing ability to identify the latest cybersecurity vulnerabilities. Given the critical utility provided by the ongoing software updates and updated ability to identify network vulnerabilities included in maintenance, we combine the perpetual license and the maintenance into a single performance obligation. Perpetual license arrangements generally contain a material right related to the customer&#x2019;s ability to renew maintenance at a price that is less than the initial license fee. We apply a practical alternative to allocating a portion of the transaction price to the material right performance obligation and estimate a hypothetical transaction price which includes fees for expected maintenance renewals based on the estimated economic life of the perpetual license contracts. We allocate the transaction price between the cybersecurity subscription provided in the initial contract and the material right related to expected contract renewals based on the hypothetical transaction price. We recognize the amount allocated to the combined license and maintenance performance obligation over the initial contractual period, which is generally &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;one year&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;. We recognize the amount allocated to the material right over the expected maintenance renewal period, which begins at the end of the initial contractual term and is generally &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;four years&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;. We have estimated the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;five&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;-year economic life of perpetual license contracts based on historical contract attrition, expected renewal periods, the lifecycle of the our technology and other factors. While we believe that the estimates we have made are reasonable and appropriate, different assumptions and estimates could materially impact our reported financial results.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Professional Services and Other Revenue&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Professional services and other revenue is primarily comprised of advisory services and training related to the deployment and optimization of our products. These services do not result in significant customization of our products. Professional services and other revenue is recognized as the services are performed. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Contracts with Multiple Performance Obligations&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;In cases where our contracts with customers contain multiple performance obligations, the contract transaction price is allocated on a relative standalone selling price basis. We typically determine standalone selling price based on observable selling prices of our products and services. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Variable Consideration &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;We record revenue from sales at the net sales price, which is the transaction price, including estimates of variable consideration when applicable. Certain of our customers may be entitled to receive credits and in certain circumstances, refunds, if service level commitments are not met. We have not historically experienced significant incidents affecting the ability to meet these service level commitments and any estimated refunds related to these agreements have not been material. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Sales through our channel network of distributors and resellers are generally discounted as compared to the price that we would sell to an end user. Revenue for sales through our channel network is recorded net of any distributor or reseller margin. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Concentrations &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;We sell and market our products and services through our field sales force that works closely with our channel partners, which includes a network of distributors and resellers, in developing sales opportunities.  We use a&#160;two-tiered&#160;channel model whereby we sell our products and services to our distributors, which in turn sell to resellers, which then sell to end-users.  We derived &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;90%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; of revenue through our channel network in the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;three and six months ended June 30, 2019&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;87%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; of revenue in the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;three and six months ended June 30, 2018&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;.

Contract liabilities consist of deferred revenue and include customer billings and payments received in advance of performance under the contract. In the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;three months ended June 30, 2019&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;2018&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; and the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;six months ended June 30, 2019&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;2018&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;, we recognized revenue of &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;$78.3 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;$51.7 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;, &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;$136.7 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;$99.2 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;, respectively, that was included in the deferred revenue balance at the beginning of each of the respective periods.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Remaining Performance Obligations&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;At &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;June&#160;30, 2019&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;, the future estimated revenue related to unsatisfied performance obligations was &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;$313.0 million&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;, with &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;74%&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; expected to be recognized as revenue over the succeeding &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;twelve months&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;, and the remainder expected to be recognized over the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;four years&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; thereafter.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;"&gt;Investments&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;We currently invest in commercial paper, corporate bonds and U.S. treasury and agency obligations. Our investments are classified as available-for-sale and recorded at fair value, with unrealized gains and losses reported in accumulated other comprehensive income within stockholders&#x2019; equity (deficit). We periodically review our investment portfolio to determine whether investments have indicators of possible impairment. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;padding-left:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;"&gt;Deferred Commissions&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Sales commissions, including related incremental fringe benefit costs, are considered to be incremental costs of obtaining a contract. Sales commissions on initial sales are not commensurate with sales commissions on contract renewals and therefore are recognized over an estimated period of benefit, which ranges between &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;three&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;four&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; years for subscription arrangements and &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;five&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt; years for perpetual license arrangements. We estimate the period of benefit based on the expected contract term including renewal periods, the lifecycle of our technology, and other factors. Sales commissions on contract renewals are capitalized and amortized ratably over the contract term, with the exception of contracts with renewal periods that are one year or less, in which case the incremental costs are expensed as incurred.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;The

842"),&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt; &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;as of January 1, 2018 using the modified retrospective method. We elected the package of practical expedients as permitted under the transition guidance, which allowed us to not reassess whether arrangements contain leases, not reassess lease classification, and not reassess initial direct costs.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;The impact of the adoption of ASC 842 on previously reported interim financial statements included the recognition of right-of-use ("ROU") assets and lease liabilities, as well as the derecognition of the construction-in-progress and construction financing obligation. There was no material impact to previously reported results of operations for any interim period.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;We determine if an arrangement contains a lease and the classification of that lease, if applicable, at inception. We have elected to not recognize a lease liability or ROU asset for short-term leases (leases with a term of twelve months or less). For contracts with lease and non-lease components, we have elected to not allocate the contract consideration, and account for the lease and non-lease components as a single lease component. Additionally, we enter into arrangements to use shared office spaces and other facilities, and have determined that these arrangements do not contain leases as we do not have the right to use an identified asset. Operating leases are included in operating lease ROU assets, operating lease liabilities and operating lease liabilities (net of current portion) in our consolidated balance sheets. Finance leases are included in property and equipment, other current liabilities and other liabilities in our consolidated balance sheets. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments under the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The implicit rate within our operating leases is generally not determinable and we use our incremental borrowing rate at the lease commencement date to determine the present value of lease payments. The determination of our incremental borrowing rate requires judgment. We determine our incremental borrowing rate for each lease using our current borrowing rate, adjusted for various factors including level of collateralization, term and currency to align with the terms of the lease. The operating lease ROU asset also includes any lease prepayments, offset by lease incentives. Certain of our leases include options to extend or terminate the lease. An option to extend the lease is considered in connection with determining the ROU asset and lease liability when it is reasonably certain we will exercise that option. An option to terminate is considered unless it is reasonably certain we will not exercise the option.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Lease expense for lease payments is recognized on a straight-line basis over the term of the lease.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;"&gt;Recent Accounting Pronouncements Not Yet Adopted&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13 &#x2014;&#160;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Financial Instruments-Credit Losses (Topic 326)&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;:&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt; Measurement of Credit Losses on Financial Instruments&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;. This ASU amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities to require that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down. The measurement of credit losses for newly recognized financial assets and subsequent changes in the allowance for credit losses are recorded in the statements of operations.

arrangements generally have annual or multi-year contractual terms for the use of our software or cloud solutions, including ongoing software updates and the ability to identify the latest cybersecurity vulnerabilities. Revenue is recognized ratably over the subscription term given the critical utility provided by the ongoing updates that are released throughout the contract period. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Perpetual License and Maintenance Revenue &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Our perpetual licenses are generally sold with one or more years of maintenance, which include ongoing software updates and the ongoing ability to identify the latest cybersecurity vulnerabilities. Given the critical utility provided by the ongoing software updates and updated ability to identify network vulnerabilities included in maintenance, we combine the perpetual license and the maintenance into a single performance obligation. Perpetual license arrangements generally contain a material right related to the customer&#x2019;s ability to renew maintenance at a price that is less than the initial license fee. We apply a practical alternative to allocating a portion of the transaction price to the material right performance obligation and estimate a hypothetical transaction price which includes fees for expected maintenance renewals based on the estimated economic life of the perpetual license contracts. We allocate the transaction price between the cybersecurity subscription provided in the initial contract and the material right related to expected contract renewals based on the hypothetical transaction price. We recognize the amount allocated to the combined license and maintenance performance obligation over the initial contractual period, which is generally &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;one year&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;. We recognize the amount allocated to the material right over the expected maintenance renewal period, which begins at the end of the initial contractual term and is generally &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&lt;span&gt;four years&lt;/span&gt;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;. We have estimated the &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;five&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;-year economic life of perpetual license contracts based on historical contract attrition, expected renewal periods, the lifecycle of the our technology and other factors. While we believe that the estimates we have made are reasonable and appropriate, different assumptions and estimates could materially impact our reported financial results.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Professional Services and Other Revenue&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Professional services and other revenue is primarily comprised of advisory services and training related to the deployment and optimization of our products. These services do not result in significant customization of our products. Professional services and other revenue is recognized as the services are performed. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Contracts with Multiple Performance Obligations&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;"&gt; &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;In cases where our contracts with customers contain multiple performance obligations, the contract transaction price is allocated on a relative standalone selling price basis. We typically determine standalone selling price based on observable selling prices of our products and services. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Variable Consideration &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;We record revenue from sales at the net sales price, which is the transaction price, including estimates of variable consideration when applicable. Certain of our customers may be entitled to receive credits and in certain circumstances, refunds, if service level commitments are not met. We have not historically experienced significant incidents affecting the ability to meet these service level commitments and any estimated refunds related to these agreements have not been material. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Sales through our channel network of distributors and resellers are generally discounted as compared to the price that we would sell to an end user. Revenue for sales through our channel network is recorded net of any distributor or reseller margin. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:justify;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Concentrations &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;We sell and market our products and services through our field sales force that works closely with our channel partners, which includes a network of distributors and resellers, in developing sales opportunities.  We use a&#160;two-tiered&#160;channel model whereby we sell our products and services to our distributors, which in turn sell to resellers, which then sell to end-users.

We elected the package of practical expedients as permitted under the transition guidance, which allowed us to not reassess whether arrangements contain leases, not reassess lease classification, and not reassess initial direct costs.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;The impact of the adoption of ASC 842 on previously reported interim financial statements included the recognition of right-of-use ("ROU") assets and lease liabilities, as well as the derecognition of the construction-in-progress and construction financing obligation. There was no material impact to previously reported results of operations for any interim period.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;We determine if an arrangement contains a lease and the classification of that lease, if applicable, at inception. We have elected to not recognize a lease liability or ROU asset for short-term leases (leases with a term of twelve months or less). For contracts with lease and non-lease components, we have elected to not allocate the contract consideration, and account for the lease and non-lease components as a single lease component. Additionally, we enter into arrangements to use shared office spaces and other facilities, and have determined that these arrangements do not contain leases as we do not have the right to use an identified asset. Operating leases are included in operating lease ROU assets, operating lease liabilities and operating lease liabilities (net of current portion) in our consolidated balance sheets. Finance leases are included in property and equipment, other current liabilities and other liabilities in our consolidated balance sheets. &lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments under the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The implicit rate within our operating leases is generally not determinable and we use our incremental borrowing rate at the lease commencement date to determine the present value of lease payments. The determination of our incremental borrowing rate requires judgment. We determine our incremental borrowing rate for each lease using our current borrowing rate, adjusted for various factors including level of collateralization, term and currency to align with the terms of the lease. The operating lease ROU asset also includes any lease prepayments, offset by lease incentives. Certain of our leases include options to extend or terminate the lease. An option to extend the lease is considered in connection with determining the ROU asset and lease liability when it is reasonably certain we will exercise that option. An option to terminate is considered unless it is reasonably certain we will not exercise the option.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;Lease expense for lease payments is recognized on a straight-line basis over the term of the lease.&lt;/span&gt;&lt;/div&gt;</us-gaap:LesseeLeasesPolicyTextBlock>

This ASU amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities to require that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down. The measurement of credit losses for newly recognized financial assets and subsequent changes in the allowance for credit losses are recorded in the statements of operations. This guidance is effective for us beginning January 1, 2020, and will be adopted using the modified-retrospective method. We are currently evaluating the potential impact of this standard on our consolidated financial statements.&lt;/span&gt;&lt;/div&gt;&lt;div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;In August 2018, the FASB issued ASU No. 2018-15 &#x2014;&#160;&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Intangibles &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&#x2014; &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Goodwill and Other &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;&#x2014; &lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;font-style:italic;"&gt;Internal-Use Software (Subtopic 350-40): Customer&#x2019;s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract&lt;/span&gt;&lt;span style="font-family:Arial;font-size:10pt;"&gt;. Under this ASU, implementation costs related to a cloud computing arrangement that is a service contract will be capitalized consistent with the requirements for capitalizing internal-use software development costs. The capitalized implementation costs are subsequently expensed over the term of the hosting arrangement. This guidance is effective for us beginning January 1, 2020, and can be adopted prospectively or retrospectively. We are currently evaluating adoption methods and the impact of this standard.&lt;/span&gt;&lt;/div&gt;</us-gaap:NewAccountingPronouncementsPolicyPolicyTextBlock>

multi-year contractual terms for the use of our software or cloud solutions, including ongoing software updates and the ability to identify the latest cybersecurity vulnerabilities. Revenue is recognized ratably over the subscription term given the critical utility provided by the ongoing updates that are released throughout the contract period. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Perpetual License and Maintenance Revenue </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our perpetual licenses are generally sold with one or more years of maintenance, which include ongoing software updates and the ongoing ability to identify the latest cybersecurity vulnerabilities. Given the critical utility provided by the ongoing software updates and updated ability to identify network vulnerabilities included in maintenance, we combine the perpetual license and the maintenance into a single performance obligation. Perpetual license arrangements generally contain a material right related to the customer&#8217;s ability to renew maintenance at a price that is less than the initial license fee. We apply a practical alternative to allocating a portion of the transaction price to the material right performance obligation and estimate a hypothetical transaction price which includes fees for expected maintenance renewals based on the estimated economic life of the perpetual license contracts. We allocate the transaction price between the cybersecurity subscription provided in the initial contract and the material right related to expected contract renewals based on the hypothetical transaction price. We recognize the amount allocated to the combined license and maintenance performance obligation over the initial contractual period, which is generally </span><span style="font-family:Arial;font-size:10pt;"><span>one year</span></span><span style="font-family:Arial;font-size:10pt;">. We recognize the amount allocated to the material right over the expected maintenance renewal period, which begins at the end of the initial contractual term and is generally </span><span style="font-family:Arial;font-size:10pt;"><span>four years</span></span><span style="font-family:Arial;font-size:10pt;">. We have estimated the </span><span style="font-family:Arial;font-size:10pt;">five</span><span style="font-family:Arial;font-size:10pt;">-year economic life of perpetual license contracts based on historical contract attrition, expected renewal periods, the lifecycle of the our technology and other factors. While we believe that the estimates we have made are reasonable and appropriate, different assumptions and estimates could materially impact our reported financial results.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Professional Services and Other Revenue</span><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;"> </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Professional services and other revenue is primarily comprised of advisory services and training related to the deployment and optimization of our products.

We estimate the period of benefit based on the expected contract term including renewal periods, the lifecycle of our technology, and other factors.

style="font-family:Arial;font-size:10pt;">("ASC 842"),</span><span style="font-family:Arial;font-size:10pt;font-style:italic;"> </span><span style="font-family:Arial;font-size:10pt;">as of January 1, 2018 using the modified retrospective method. We elected the package of practical expedients as permitted under the transition guidance, which allowed us to not reassess whether arrangements contain leases, not reassess lease classification, and not reassess initial direct costs.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The impact of the adoption of ASC 842 on previously reported interim financial statements included the recognition of right-of-use ("ROU") assets and lease liabilities, as well as the derecognition of the construction-in-progress and construction financing obligation. There was no material impact to previously reported results of operations for any interim period.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We determine if an arrangement contains a lease and the classification of that lease, if applicable, at inception. We have elected to not recognize a lease liability or ROU asset for short-term leases (leases with a term of twelve months or less). For contracts with lease and non-lease components, we have elected to not allocate the contract consideration, and account for the lease and non-lease components as a single lease component. Additionally, we enter into arrangements to use shared office spaces and other facilities, and have determined that these arrangements do not contain leases as we do not have the right to use an identified asset. Operating leases are included in operating lease ROU assets, operating lease liabilities and operating lease liabilities (net of current portion) in our consolidated balance sheets. Finance leases are included in property and equipment, other current liabilities and other liabilities in our consolidated balance sheets. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments under the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The implicit rate within our operating leases is generally not determinable and we use our incremental borrowing rate at the lease commencement date to determine the present value of lease payments. The determination of our incremental borrowing rate requires judgment. We determine our incremental borrowing rate for each lease using our current borrowing rate, adjusted for various factors including level of collateralization, term and currency to align with the terms of the lease. The operating lease ROU asset also includes any lease prepayments, offset by lease incentives. Certain of our leases include options to extend or terminate the lease. An option to extend the lease is considered in connection with determining the ROU asset and lease liability when it is reasonably certain we will exercise that option. An option to terminate is considered unless it is reasonably certain we will not exercise the option.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Lease expense for lease payments is recognized on a straight-line basis over the term of the lease.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;">Recent Accounting Pronouncements Not Yet Adopted</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016-13 &#8212;&#160;</span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Financial Instruments-Credit Losses (Topic 326)</span><span style="font-family:Arial;font-size:10pt;">:</span><span style="font-family:Arial;font-size:10pt;font-style:italic;"> Measurement of Credit Losses on Financial Instruments</span><span style="font-family:Arial;font-size:10pt;">. This ASU amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities to require that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down. The measurement of credit losses for newly recognized financial assets and subsequent changes in the allowance for credit losses are recorded in the statements of operations. This guidance is effective for us beginning January 1, 2020, and will be adopted using the modified-retrospective method. We are currently evaluating the potential impact of this standard on our consolidated financial statements.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In August 2018, the FASB issued ASU No. 2018-15 &#8212;&#160;</span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Intangibles </span><span style="font-family:Arial;font-size:10pt;">&#8212; </span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Goodwill and Other </span><span style="font-family:Arial;font-size:10pt;">&#8212; </span><span style="font-family:Arial;font-size:10pt;font-style:italic;">Internal-Use Software (Subtopic 350-40): Customer&#8217;s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract</span><span style="font-family:Arial;font-size:10pt;">. Under this ASU, implementation costs related to a cloud computing arrangement that is a service contract will be capitalized consistent with the requirements for capitalizing internal-use software development costs. The capitalized implementation costs are subsequently expensed over the term of the hosting arrangement. This guidance is effective for us beginning January 1, 2020, and can be adopted prospectively or retrospectively. We are currently evaluating adoption methods and the impact of this standard.</span></div><span></span>

Revenue is recognized ratably over the subscription term given the critical utility provided by the ongoing updates that are released throughout the contract period. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Perpetual License and Maintenance Revenue </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Our perpetual licenses are generally sold with one or more years of maintenance, which include ongoing software updates and the ongoing ability to identify the latest cybersecurity vulnerabilities. Given the critical utility provided by the ongoing software updates and updated ability to identify network vulnerabilities included in maintenance, we combine the perpetual license and the maintenance into a single performance obligation. Perpetual license arrangements generally contain a material right related to the customer&#8217;s ability to renew maintenance at a price that is less than the initial license fee. We apply a practical alternative to allocating a portion of the transaction price to the material right performance obligation and estimate a hypothetical transaction price which includes fees for expected maintenance renewals based on the estimated economic life of the perpetual license contracts. We allocate the transaction price between the cybersecurity subscription provided in the initial contract and the material right related to expected contract renewals based on the hypothetical transaction price. We recognize the amount allocated to the combined license and maintenance performance obligation over the initial contractual period, which is generally </span><span style="font-family:Arial;font-size:10pt;"><span>one year</span></span><span style="font-family:Arial;font-size:10pt;">. We recognize the amount allocated to the material right over the expected maintenance renewal period, which begins at the end of the initial contractual term and is generally </span><span style="font-family:Arial;font-size:10pt;"><span>four years</span></span><span style="font-family:Arial;font-size:10pt;">. We have estimated the </span><span style="font-family:Arial;font-size:10pt;">five</span><span style="font-family:Arial;font-size:10pt;">-year economic life of perpetual license contracts based on historical contract attrition, expected renewal periods, the lifecycle of the our technology and other factors. While we believe that the estimates we have made are reasonable and appropriate, different assumptions and estimates could materially impact our reported financial results.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;">Professional Services and Other Revenue</span><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:bold;"> </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Professional services and other revenue is primarily comprised of advisory services and training related to the deployment and optimization of our products.

There was no material impact to previously reported results of operations for any interim period.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We determine if an arrangement contains a lease and the classification of that lease, if applicable, at inception. We have elected to not recognize a lease liability or ROU asset for short-term leases (leases with a term of twelve months or less). For contracts with lease and non-lease components, we have elected to not allocate the contract consideration, and account for the lease and non-lease components as a single lease component. Additionally, we enter into arrangements to use shared office spaces and other facilities, and have determined that these arrangements do not contain leases as we do not have the right to use an identified asset. Operating leases are included in operating lease ROU assets, operating lease liabilities and operating lease liabilities (net of current portion) in our consolidated balance sheets. Finance leases are included in property and equipment, other current liabilities and other liabilities in our consolidated balance sheets. </span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments under the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. The implicit rate within our operating leases is generally not determinable and we use our incremental borrowing rate at the lease commencement date to determine the present value of lease payments. The determination of our incremental borrowing rate requires judgment. We determine our incremental borrowing rate for each lease using our current borrowing rate, adjusted for various factors including level of collateralization, term and currency to align with the terms of the lease. The operating lease ROU asset also includes any lease prepayments, offset by lease incentives. Certain of our leases include options to extend or terminate the lease. An option to extend the lease is considered in connection with determining the ROU asset and lease liability when it is reasonably certain we will exercise that option. An option to terminate is considered unless it is reasonably certain we will not exercise the option.</span></div><div style="line-height:120%;padding-bottom:16px;text-align:left;text-indent:24px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">Lease expense for lease payments is recognized on a straight-line basis over the term of the lease.</span></div><span></span>

This ASU amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities to require that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down. The measurement of credit losses for newly recognized financial assets and subsequent changes in the allowance for credit losses are recorded in the statements of operations.
