condensed consolidated financial statements of the Company have been prepared in accordance with Generally Accepted Accounting Principles
in the United States of America (&#8220;GAAP&#8221;) for interim financial information and with the instructions to Form 10-Q and Item
10-01 of Regulation S-X. Accordingly, they do not include all the information and disclosures required by GAAP for complete financial
statements. All adjustments that, in the opinion of management, are necessary for a fair presentation of the results of operations for
the interim periods have been made and are of a recurring nature unless otherwise disclosed herein. The results of operations for such
interim periods are not necessarily indicative of results of operations for a full year. These condensed consolidated financial statements
should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form
10-K for the year ended December 31, 2020, filed with the U.S. Securities and Exchange Commission (the &#8220;SEC&#8221;) on March 9,
2021. All significant intercompany balances and transactions have been eliminated in consolidation.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The Company calculates the
fair value of its assets and liabilities which qualify as financial instruments and includes this additional information in the notes
to consolidated financial statements when the fair value is different from the carrying value of these financial instruments. The estimated
fair value of accounts receivable, accounts payable and accrued expenses approximate their carrying amounts due to the relatively short
maturity of these instruments. Financing leases and Paycheck Protection Program (&#8220;PPP&#8221;) loan approximate fair value as they
bear market rates of interest. None of these instruments are held for trading purposes.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">In July 2021, the Company
determined that the combination of increased expenses primarily related with management&#8217;s accelerated increase in staffing its sales
and administrative resources together with decreased revenue expectations related to its <b>INTRUSION <i>Shield</i></b> offering has created
significant concerns about the Company&#8217;s ability to meet its current and short-term cash-flow and liquidity needs, over the next
12 months. In recognition of this determination, the Company has been actively considering strategic alternatives for the funding and
implementation of its long-term business plan. For example, the Company has engaged B. Riley Securities, Inc. to act as sales agent under
its at-the-market program, which allows the Company to potentially sell up to $50.0 million of its common stock on a delayed or continuous
basis through the use of a shelf-registration statement on Form S-3, which the Company initially filed on August 5, 2021. The shelf registration
became effective on August 16, 2021. As of September 30, 2021, the Company received net proceeds in the amount of $<span id="xdx_901_eus-gaap--ProceedsFromIssuanceOrSaleOfEquity_pn3n3_dm_c20210101__20210930_zy1LcizkLT17" title="Proceed from sales of stock"><ix:nonFraction name="us-gaap:ProceedsFromIssuanceOrSaleOfEquity" contextRef="From2021-01-01to2021-09-30" format="ixt:numdotdecimal" decimals="-3" scale="6" unitRef="USD">4.8</ix:nonFraction></span> million net of

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Management believes that
this plan may continue to provide the Company with the financing required to continue as a going concern; however, the Company can offer
no assurances that this at-the-market program will continue to generate the proceeds necessary to finance future operating needs. Accordingly,
the Company is currently evaluating a variety of other potential funding and longer-term strategic options.</p>

purported class action lawsuit was filed in the United States District Court, Eastern District of Texas, Sherman Division, captioned Neely
v. Intrusion Inc., et al., Case No. 4:12-cv-00374 (E.D. Tex.) against the Company, the Company&#8217;s chief financial officer, and former
chief executive officer. The Neely lawsuit alleges the same violations under the federal securities laws as those alleged in the Celeste
lawsuit. The Neely lawsuit also seeks compensatory damages and legal fees. A motion to consolidate the two lawsuits and appoint a lead
plaintiff is pending before the court. The Company believes the claims in the lawsuits are without merit and intends to defend itself
vigorously.</p>

to allocate scarce and competing resources and balance budgetary demands placed upon them as a result of the effects of the coronavirus,
mandatory quarantines, decreased travel, interruptions in workforce populations, scarcity of commodities, and similar economic and operational

product offerings and cybersecurity solutions, negatively affecting revenue levels for the Company. We anticipate that our customers will
continue to budget conservatively in the coming months, particularly as uncertainty remains about new strains and variants of the COVID-19

due to revenues from our <b><i>Shield</i></b> product line which was introduced to the market in the first quarter of 2021 and an
increase in <b><i>TraceCop </i></b>revenues between the periods. <b><i>TraceCop</i></b> revenues were $1.5 million and $4.9 million

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"><b>Concentration of Revenues</b>.
Revenues from sales to various U.S. government entities totaled $1.3 million, or 69.4% of revenues, for the quarter ended September 30,
2021, compared to $1.5 million, or 92.3% of revenues, for the same period in 2020. Revenues from sales to various U.S. government entities
totaled $3.9 million, or 69.1% of revenues, for the nine months ended September 30, 2021, compared to $4.3 million, or 84.4% of revenues,
for the same period in 2020. Sales to commercial customers totaled $0.6 million or 30.6% of total revenue for the third quarter of 2021
compared to $0.1 million or 7.7% of total revenue for the third quarter of 2020. Sales to commercial customers totaled $1.7 million or
30.9% of total revenue for the nine months ended September 30, 2021, compared to $0.8 million or 15.6% of total revenue for the nine months
period ended September 30, 2020. Although we expect our concentration of revenues to vary among customers in future periods depending
upon the timing of certain sales, we anticipate that sales to government customers will continue to account for a significant portion
of our revenues in future periods. Sales to the government present risks in addition to those involved in sales to commercial customers
which could adversely affect our revenues, including, without limitation, potential disruption to appropriation and spending patterns
and the government&#8217;s reservation of the right to cancel contracts and purchase orders for its convenience. Although we do not anticipate
that any of our revenues with government customers will be renegotiated, any cancelled or renegotiated government orders could have a
material adverse effect on our financial results. Currently, we are not aware of any proposed cancellation or renegotiation of any of
our existing arrangements with government entities and, historically, cancellations or renegotiated orders by government entities have
not resulted in a material adverse effect on our business. One individual commercial customer during the nine months ended September 30,
2021, individually accounted for over 10.0% of total revenues and during the three months ended September 30, 2021, two individual commercial
customers accounted for revenues that were individually over 10.0% of total revenues. During the three and nine months ended September
30, 2020, no individual commercial customer accounted for revenues that were over 10.0% of total revenues. The Company&#8217;s similar
product and service offerings are not viewed as individual segments, as its management analyzes the business as a whole and expenses are
not allocated to each product offering.</p>

compared to $3.0 million or 59.3% of revenues for the nine months ended September 30, 2020, with the changes mainly due to changes in
the <b><i>TraceCop</i></b>/<b><i>Savant</i></b> product mix. Gross profit as a percentage of revenues is impacted by several factors,
including shifts in product mix, changes in channel of distributions, revenue volume, pricing strategies, and fluctuations in revenues
of integrated third-party products.</p>

179.7% of revenues for the nine months ended September 30, 2021, compared to $1.9 million or 37.3% of revenues for the nine months ended
September 30, 2020. The increase is primarily related to an aggressive ramp up in labor cost, web marketing and other forms of business
development advertising costs including $0.6 million related to a trade show event in anticipation of increased revenues from the sales
of our new commercial product. The anticipated revenues from our <b>INTRUSION <i>Shield</i></b> product have been slow to materialize
and as a result we determined that these sales costs should be reduced. During the third quarter of 2021, we started implementing certain
cost saving measures such as a reduction in force as well as negotiations with certain contractors and vendors to appropriately align
our expenses with our revenue trends.</p>

September 30, 2020. The increase in research and development expense was due to increases in direct labor expenses and increases in costs
associated with the development and testing of our legacy and <b><i>Shield</i></b> products. As discussed above, during the third quarter
of 2021, we started implementing certain cost saving measures such as a reduction in force as well as negotiations with certain contractors
and vendors to appropriately align our expenses with our revenue trends. Research and development costs are expensed in the period in
which they are incurred. Research and development expenses may vary in the future; mainly dependent on levels of research and development
labor expense charged to direct labor.</p>

months ended September 30, 2020. The increase in general and administrative costs was also related to an aggressive ramp up in general
and administrative costs in anticipation of increased revenues from sales of our new <b><i>Shield </i></b>commercial product which have
been slow to materialize. Some of the more significant increases include: Employee related expenses such as direct labor, benefits, recruitment
agency fees, officer liability insurance and contract labor costs increased by $1.1 million and $3.0 million during the three and nine
months ended September 30, 2021, when compared to the same periods in 2020. Legal costs increased by $0.6 million and $0.9 million specifically
related to non-recurring projects during the three and nine months ended September 30, 2021, when compared to the same periods in 2020.
Stock compensation expense decreased by $60,000 and increased by $0.5 million during the three and nine months ended September 30, 2021,
when compared to the same periods in 2020. The increase during the nine months ended September 30, 2021, was related to options granted
to new employees as well as compensation expense recognized during this period, related to the accelerated vesting of stock options granted
to certain members of our Board upon retirement during the nine months ended September 30, 2021, when compared to the same period in 2020.
The decrease during the three months ended September 30, 2021, was due to increases in new awards granted during the nine month period
ended September 30, 2021 that did not exist during the same period in 2020 leading to no expense recognized on these 2021 grants during
the three and nine months ended September 30, 2020, offset by a reduction in expense related to the forfeiture of compensation expense
as a result of recent employee resignations, terminations and departures that occurred during the third quarter of 2021. The results of
the recent employee resignations, terminations and departures during the three months ended September 30, 2021, was a decrease in stock
compensation expense of $0.6 million. For the three and nine months ended September 30, 2021, costs allocated to other departments within
the research and development group and the sales and marketing group increased by $1.1 million and $2.0 million during the three and nine
months ended September 30, 2021, when compared with the same periods in 2020. On July 29, 2021, the Company executed a planned reduction
in force resulting in the termination of approximately 20% of its employees across the organization. The reduction in force was part of
a larger effort on the Company&#8217;s part to reduce expenses and overhead as a result of the challenges the Company anticipates in meeting
its liquidity and cash-flow needs in the near term, as a result of lower-than-expected 2021 revenues from its newly introduced <b>INTRUSION

arrangement in the amount of $1.8 million. $1.5 million of which related to new server systems replacing our old and outdated sever systems

products and technologies that are complementary to our existing business. We are continuing to identify and prioritize additional security
technologies, which we may wish to develop, either internally or through the licensing, or acquisition of products from third parties.
While we may engage from time to time in discussions with respect to potential acquisitions, there can be no assurances that any such
acquisitions will be made or that we will be able to successfully integrate any acquired business. In order to finance such acquisitions
and working capital, it may be necessary for us to raise additional funds through public or private financings. Any equity or debt financings,
if available at all, may be on terms, which are not favorable to us and, in the case of equity financings, may result in dilution to our
stockholders.</p>

legal proceedings in the District Court of Dallas County, Texas, 14<sup>th</sup> Judicial District against Purple Plaza LLC, the landlord
for the facilities we previously occupied in Richardson, Texas. This lawsuit claims damages for breach of contract for, among other things,
failure to maintain and repair the leased facilities and to provide adequate heating, air conditioning and ventilation on the premises,
resulting in a constructive eviction. Intrusion is seeking damages in excess of $1,000,000 together with a declaratory judgment that any
of Intrusion&#8217;s remaining obligations under the lease have terminated.&#160; Purple Plaza, LLC has answered by filing a general denial,
and recently added a counterclaim seeking alleged past due rent in the amount of approximately $229,000 and future rent allegedly exceeding
$2.0 million without offsetting its duty to mitigate its damages. Discovery is underway in the matter. The case is set for jury trial

been actively considering strategic alternatives for the funding and implementation of our long-term business plan. For example, we have
engaged B. Riley Securities, Inc. to act as sales agent under our at-the-market program, which allows us to potentially sell up to $50.0
million of our common stock on a delayed or continuous basis through the use of a shelf-registration statement on Form S-3, which we initially

10-K for the year ended December 31, 2020, filed with the U.S. Securities and Exchange Commission (the &#x201c;SEC&#x201d;) on March 9,
2021. All significant intercompany balances and transactions have been eliminated in consolidation.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;The Company calculates the
fair value of its assets and liabilities which qualify as financial instruments and includes this additional information in the notes
to consolidated financial statements when the fair value is different from the carrying value of these financial instruments. The estimated
fair value of accounts receivable, accounts payable and accrued expenses approximate their carrying amounts due to the relatively short
maturity of these instruments. Financing leases and Paycheck Protection Program (&#x201c;PPP&#x201d;) loan approximate fair value as they
bear market rates of interest. None of these instruments are held for trading purposes.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;In July 2021, the Company
determined that the combination of increased expenses primarily related with management&#x2019;s accelerated increase in staffing its sales
and administrative resources together with decreased revenue expectations related to its &lt;b&gt;INTRUSION &lt;i&gt;Shield&lt;/i&gt;&lt;/b&gt; offering has created
significant concerns about the Company&#x2019;s ability to meet its current and short-term cash-flow and liquidity needs, over the next
12 months. In recognition of this determination, the Company has been actively considering strategic alternatives for the funding and
implementation of its long-term business plan. For example, the Company has engaged B. Riley Securities, Inc. to act as sales agent under
its at-the-market program, which allows the Company to potentially sell up to $50.0 million of its common stock on a delayed or continuous
basis through the use of a shelf-registration statement on Form S-3, which the Company initially filed on August 5, 2021. The shelf registration
became effective on August 16, 2021. As of September 30, 2021, the Company received net proceeds in the amount of $&lt;span id="xdx_901_eus-gaap--ProceedsFromIssuanceOrSaleOfEquity_pn3n3_dm_c20210101__20210930_zy1LcizkLT17" title="Proceed from sales of stock"&gt;4.8&lt;/span&gt; million net of
fees from the sale of its common stock related to this program.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;Management believes that
this plan may continue to provide the Company with the financing required to continue as a going concern; however, the Company can offer
no assurances that this at-the-market program will continue to generate the proceeds necessary to finance future operating needs. Accordingly,
the Company is currently evaluating a variety of other potential funding and longer-term strategic options.&lt;/p&gt;

Company accounts for stock-based compensation in accordance with ASC 718, &lt;i&gt;Compensation &#x2013; Stock Compensation&lt;/i&gt;, which requires
that compensation related to all stock-based awards be recognized in the condensed consolidated financial statements. Stock-based compensation
cost is valued at fair value at the date of grant, and the grant date fair value is recognized as expense over each award&#x2019;s requisite
service period with a corresponding increase to equity or liability based on the terms of each award and the appropriate accounting treatment
under ASC 718.&lt;/span&gt;&lt;/p&gt;

2021, the Company added a new incentive plan (the &#x201c;2021 Omnibus Incentive Plan&#x201d;). The purpose of the 2021 Omnibus Incentive
Plan is to provide a means through which the Company may attract and retain key personnel and to provide a means whereby directors, officers,
employees, consultants and advisors of the Company can acquire and maintain an equity interest in the Company, or be paid incentive compensation,
including incentive compensation measured by reference to the value of common stock, thereby strengthening their commitment to the welfare
of the Company and aligning their interests with those of the Company&#x2019;s stockholders.&lt;/span&gt;&lt;/p&gt;

the nine-month period ended September 30, 2021, the Company issued new Restricted Stock Awards (RSAs) under the 2021 Omnibus Incentive
Plan in the amount of $&lt;span id="xdx_90D_eus-gaap--StockIssuedDuringPeriodValueRestrictedStockAwardGross_c20210101__20210930__srt--CounterpartyNameAxis__custom--OutsideDirectorsMember_zYMBdEoSYQ71"&gt;70,000&lt;/span&gt; in value of restricted stock to each of the Company&#x2019;s outside directors, with a valuation to be based

volatility is based on historical volatility and in part on implied volatility. The expected term considers the contractual term of the
option as well as historical exercise and forfeiture behavior. The risk-free interest rate is based on the rates in effect on the grant
date for U.S. Treasury instruments with maturities matching the relevant expected term of the award. Options granted to non-employees
are valued using the fair market value on each measurement date of the option.&lt;/span&gt;&lt;/p&gt;

updates are typically done monthly, and revenue is matched accordingly. Product sales may include maintenance and customer support allocated
revenue in an arrangement using estimated selling prices of the delivered goods and services based on a selling price hierarchy using
the relative selling price method. All product offering and service offering market values are readily determined based on current and
prior stand-alone sales. The Company may defer and recognize maintenance, updates and support revenue over the term of the contract period,
which is generally one year.&lt;/span&gt;&lt;/p&gt;

payment terms offered to customers, distributors and resellers are net 30 days domestically and net 45 days internationally. The Company
does not offer payment terms that extend beyond one year and rarely does it extend payment terms beyond its normal terms. If certain
customers do not meet the Company&#x2019;s credit standards, the Company typically requires payment in advance on some of its smaller
sized customers to limit its credit exposure.&lt;/span&gt;&lt;/p&gt;

the Company&#x2019;s newest product, &lt;b&gt;&lt;i&gt;Shield&lt;/i&gt;&lt;/b&gt;, Intrusion began offering software on a subscription basis. Shield is a hosted

net loss per share is computed by dividing net loss attributable to common stockholders for the period by the weighted average number
of common shares outstanding for the period. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders
by the weighted average number of common shares and dilutive common stock equivalents outstanding for the period. Our common stock equivalents
include all common stock issuable upon conversion of preferred stock and the exercise of outstanding options and warrants. &lt;span style="background-color: white"&gt;The

Company is periodically involved in claims asserted in the normal course of its business. We believe these actions are routine and incidental
to the business. While the outcome of these actions cannot be predicted with certainty, we do not believe that any will have a material
adverse impact on our business.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;On April 16, 2021, a purported
class action lawsuit was filed in the United States District Court, Eastern District of Texas, Sherman Division, captioned Celeste v.
Intrusion Inc. et al., Case No. 4:21-cv-00307 (E.D.Tex) against the Company, the Company&#x2019;s chief financial officer, and former chief
executive officer alleging, among other things, that the defendants made false and/or misleading statements or omissions about the Company&#x2019;s
business, operations, and prospects in violation of Section 10(b) of The Securities Exchange Act of 1934, as amended (the &#x201c;Exchange
Act&#x201d;), and Rule 10b-5 promulgated thereunder, as well as Section 20(a) of the Exchange Act. The Celeste lawsuit claims compensatory
damages and legal fees.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;On May 14, 2021, a related
purported class action lawsuit was filed in the United States District Court, Eastern District of Texas, Sherman Division, captioned Neely
v. Intrusion Inc., et al., Case No. 4:12-cv-00374 (E.D. Tex.) against the Company, the Company&#x2019;s chief financial officer, and former
chief executive officer. The Neely lawsuit alleges the same violations under the federal securities laws as those alleged in the Celeste
lawsuit. The Neely lawsuit also seeks compensatory damages and legal fees. A motion to consolidate the two lawsuits and appoint a lead
plaintiff is pending before the court. The Company believes the claims in the lawsuits are without merit and intends to defend itself
vigorously.&lt;/p&gt;

the ultimate outcome and is unable to make a meaningful estimate of the amount or range of loss, if any, that could result from any unfavorable
outcome of the Class Action Litigation.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;On August 8, 2021, the Company
received a notification from the Securities and Exchange Commission, Division of Enforcement, that it was conducting an investigation
captioned In the Matter of Intrusion Inc. and requesting the Company produce certain documents and information. On November 9, 2021, the
Securities and Exchange Commission served a subpoena on the Company in connection with this investigation which formally requested substantially
similar information as in the prior request. The Company is continuing to comply with the requests and is cooperating in the investigation.
The Company can offer no assurances as to the outcome of this investigation or its potential effect on the Company or its results of operations.&lt;/p&gt;

Company has operating and finance leases where it records the right-of-use assets and a related lease liability as required under ASC
842. The lease liabilities are determined by the net present value of total lease payments and amortized over the life of the lease.
All obligations under the Company&#x2019;s lease agreements are designed to terminate with the last scheduled payment. The Company&#x2019;s
leases are for the following types of assets:&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

    a three-year life and are in various stages of completion.&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;

    &lt;td style="text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;Office space - The Company&#x2019;s
    operating lease right-of-use assets include its rental agreements for its offices in Plano, TX, and San Marcos, CA, and a data service
    center in Allen, TX. The Plano offices operating lease liability was modified during the three months ended September 30, 2021, to
    add an additional floor of office space and terminate the prior lease. The modified lease has a life of two years and one month as
    of September 30, 2021. The San Marcos operating lease liability terminated on March 31, 2021. The data service center operating lease
    liability has a life of four years and one month as of September 30, 2021. The Company also has an operating lease liability for
    its former corporate office in Richardson. The Richardson operating lease liability has a life of three years and two months as of
    September 30, 2021; however, the related right-of-use asset was fully impaired due to the Company&#x2019;s abandonment of the lease
    as of December 31, 2020.&lt;/span&gt;&lt;/td&gt;&lt;/tr&gt;

qualitative and quantitative disclosures regarding the Company's leasing arrangements are also required. The Company adopted ASC 842
prospectively and elected the package of transition practical expedients that does not require reassessment of: (1) whether any existing
or expired contracts are or contain leases, (2) lease classification and (3) initial direct costs. In addition, the Company has elected
other available practical expedients to not separate lease and non-lease components, which consist principally of common area maintenance
charges, for all classes of underlying assets and to exclude leases with an initial term of 12 months or less.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

the implicit rate is not readily determinable for the Company's lease agreement, the Company uses an estimated incremental borrowing
rate to determine the initial present value of lease payments. This discount rate for the lease approximates Silicon Valley Bank's prime
rate.&lt;/span&gt;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&lt;span style="font: 10pt Times New Roman, Times, Serif"&gt;&#160;&lt;/span&gt;&lt;/p&gt;

to allocate scarce and competing resources and balance budgetary demands placed upon them as a result of the effects of the coronavirus,
mandatory quarantines, decreased travel, interruptions in workforce populations, scarcity of commodities, and similar economic and operational
effects of the virus upon their own constituencies. These adverse effects resulted in decreased demand by many of our customers for our
product offerings and cybersecurity solutions, negatively affecting revenue levels for the Company. We anticipate that our customers will
continue to budget conservatively in the coming months, particularly as uncertainty remains about new strains and variants of the COVID-19
virus and potential future restrictions, slow-downs, or lock-downs.&lt;/p&gt;

&lt;/table&gt;


&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;On March 27, 2020, the U.S.
federal government enacted the Coronavirus Aid, Relief, and Economic Security Act (&#x201c;CARES Act&#x201d;), which included provision
for a Paycheck Protection Program (&#x201c;PPP&#x201d;) administered by the U.S. Small Business Administration (&#x201c;SBA&#x201d;). The
PPP allowed qualifying businesses to borrow up to $10 million calculated based on qualifying payroll costs. The loan was guaranteed by
the federal government and did not require collateral. On April&#160;30, 2020, the Company entered a PPP Loan with Silicon Valley Bank,
pursuant to the PPP under CARES Act for a principal amount of $&lt;span id="xdx_90F_eus-gaap--ProceedsFromIssuanceOfLongTermDebt_c20200101__20200430__us-gaap--LongtermDebtTypeAxis__custom--PaycheckProtectionProgramCaresActMember_pn3p0" title="Proceeds from Issuance of Long-term Debt, Total"&gt;629,000&lt;/span&gt;. The PPP Loan was to mature on &lt;span id="xdx_909_eus-gaap--DebtInstrumentMaturityDate_dd_c20200101__20200430__us-gaap--LongtermDebtTypeAxis__custom--PaycheckProtectionProgramCaresActMember_zACnwuIXfMxg" title="Debt maturity date"&gt;April 30, 2022&lt;/span&gt;, and bear interest
at a rate of &lt;span id="xdx_901_eus-gaap--DebtInstrumentInterestRateDuringPeriod_dp_c20200101__20200430__us-gaap--LongtermDebtTypeAxis__custom--PaycheckProtectionProgramCaresActMember_zRGUSJu8c4vk" title="Interest rate"&gt;1.0&lt;/span&gt;% per annum. The Company received the PPP Loan funds on April 30, 2020. The PPP Loan contained events of default and other
provisions customary for a loan of this type. The PPP provided that (1) the use of PPP Loan amount shall be limited to certain qualifying
expenses, (2) 100% of the principal amount of the loan is guaranteed by the SBA and (3) an amount up to the full principal amount plus
accrued interest may qualify for loan forgiveness in accordance with the terms of CARES Act.&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;&#160;&lt;/p&gt;

&lt;p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in"&gt;The Company utilized the
full proceeds of the PPP loan in accordance with the provisions of CARES Act and submitted the PPP Loan Forgiveness Application. On April
7, 2021, the Company received notice from the SBA that the PPP loan and accrued interest was forgiven in full. As a result, the Company
recorded gain in the extinguishment of debt of $&lt;span id="xdx_909_eus-gaap--GainsLossesOnExtinguishmentOfDebt_c20210101__20210930_pn3p0" title="Gain (Loss) on Extinguishment of Debt"&gt;635,000&lt;/span&gt; on its condensed statement of operations during the nine months ended September

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The accompanying unaudited
condensed consolidated financial statements of the Company have been prepared in accordance with Generally Accepted Accounting Principles
in the United States of America (&#8220;GAAP&#8221;) for interim financial information and with the instructions to Form 10-Q and Item
10-01 of Regulation S-X. Accordingly, they do not include all the information and disclosures required by GAAP for complete financial
statements. All adjustments that, in the opinion of management, are necessary for a fair presentation of the results of operations for
the interim periods have been made and are of a recurring nature unless otherwise disclosed herein. The results of operations for such
interim periods are not necessarily indicative of results of operations for a full year. These condensed consolidated financial statements
should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form
10-K for the year ended December 31, 2020, filed with the U.S. Securities and Exchange Commission (the &#8220;SEC&#8221;) on March 9,
2021. All significant intercompany balances and transactions have been eliminated in consolidation.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The Company calculates the
fair value of its assets and liabilities which qualify as financial instruments and includes this additional information in the notes
to consolidated financial statements when the fair value is different from the carrying value of these financial instruments. The estimated
fair value of accounts receivable, accounts payable and accrued expenses approximate their carrying amounts due to the relatively short
maturity of these instruments. Financing leases and Paycheck Protection Program (&#8220;PPP&#8221;) loan approximate fair value as they
bear market rates of interest. None of these instruments are held for trading purposes.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">In July 2021, the Company
determined that the combination of increased expenses primarily related with management&#8217;s accelerated increase in staffing its sales
and administrative resources together with decreased revenue expectations related to its <b>INTRUSION <i>Shield</i></b> offering has created
significant concerns about the Company&#8217;s ability to meet its current and short-term cash-flow and liquidity needs, over the next
12 months. In recognition of this determination, the Company has been actively considering strategic alternatives for the funding and
implementation of its long-term business plan. For example, the Company has engaged B. Riley Securities, Inc. to act as sales agent under
its at-the-market program, which allows the Company to potentially sell up to $50.0 million of its common stock on a delayed or continuous
basis through the use of a shelf-registration statement on Form S-3, which the Company initially filed on August 5, 2021. The shelf registration
became effective on August 16, 2021. As of September 30, 2021, the Company received net proceeds in the amount of $<span id="xdx_901_eus-gaap--ProceedsFromIssuanceOrSaleOfEquity_pn3n3_dm_c20210101__20210930_zy1LcizkLT17" title="Proceed from sales of stock">4.8</span> million net of
fees from the sale of its common stock related to this program.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">&#160;</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">Management believes that
this plan may continue to provide the Company with the financing required to continue as a going concern; however, the Company can offer
no assurances that this at-the-market program will continue to generate the proceeds necessary to finance future operating needs. Accordingly,
the Company is currently evaluating a variety of other potential funding and longer-term strategic options.</p>

volatility is based on historical volatility and in part on implied volatility. The expected term considers the contractual term of the
option as well as historical exercise and forfeiture behavior. The risk-free interest rate is based on the rates in effect on the grant

are valued using the fair market value on each measurement date of the option.</span></p>

to allocate scarce and competing resources and balance budgetary demands placed upon them as a result of the effects of the coronavirus,
mandatory quarantines, decreased travel, interruptions in workforce populations, scarcity of commodities, and similar economic and operational
effects of the virus upon their own constituencies. These adverse effects resulted in decreased demand by many of our customers for our
product offerings and cybersecurity solutions, negatively affecting revenue levels for the Company. We anticipate that our customers will
continue to budget conservatively in the coming months, particularly as uncertainty remains about new strains and variants of the COVID-19
virus and potential future restrictions, slow-downs, or lock-downs.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">On March 27, 2020, the U.S.
federal government enacted the Coronavirus Aid, Relief, and Economic Security Act (&#8220;CARES Act&#8221;), which included provision
for a Paycheck Protection Program (&#8220;PPP&#8221;) administered by the U.S. Small Business Administration (&#8220;SBA&#8221;). The
PPP allowed qualifying businesses to borrow up to $10 million calculated based on qualifying payroll costs. The loan was guaranteed by
the federal government and did not require collateral. On April&#160;30, 2020, the Company entered a PPP Loan with Silicon Valley Bank,
pursuant to the PPP under CARES Act for a principal amount of $<span id="xdx_90F_eus-gaap--ProceedsFromIssuanceOfLongTermDebt_c20200101__20200430__us-gaap--LongtermDebtTypeAxis__custom--PaycheckProtectionProgramCaresActMember_pn3p0" title="Proceeds from Issuance of Long-term Debt, Total">629,000</span>. The PPP Loan was to mature on <span id="xdx_909_eus-gaap--DebtInstrumentMaturityDate_dd_c20200101__20200430__us-gaap--LongtermDebtTypeAxis__custom--PaycheckProtectionProgramCaresActMember_zACnwuIXfMxg" title="Debt maturity date">April 30, 2022</span>, and bear interest

The Company received the PPP Loan funds on April 30, 2020. The PPP Loan contained events of default and other
provisions customary for a loan of this type. The PPP provided that (1) the use of PPP Loan amount shall be limited to certain qualifying
expenses, (2) 100% of the principal amount of the loan is guaranteed by the SBA and (3) an amount up to the full principal amount plus
accrued interest may qualify for loan forgiveness in accordance with the terms of CARES Act.</p>

<p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0.5in">The Company utilized the
full proceeds of the PPP loan in accordance with the provisions of CARES Act and submitted the PPP Loan Forgiveness Application. On April
7, 2021, the Company received notice from the SBA that the PPP loan and accrued interest was forgiven in full. As a result, the Company
recorded gain in the extinguishment of debt of $<span id="xdx_909_eus-gaap--GainsLossesOnExtinguishmentOfDebt_c20210101__20210930_pn3p0" title="Gain (Loss) on Extinguishment of Debt">635,000</span> on its condensed statement of operations during the nine months ended September
