period of 60 months from the date of issuance. The exercise price of the Warrants is $0.60 per share, subject to adjustments as set forth
in the Warrant. We will not effect any exercise of the Warrants, and a Selling Securityholder shall not have the right to exercise any
portion of the Warrant, to the extent that after giving effect to such issuance after exercise of the Warrant, the Selling Securityholder
(together with their affiliates, and any other persons acting as a group together with the holder or any of their affiliates would beneficially
own in excess of 4.99% (or, upon election by a holder prior to the issuance of any Warrants, 9.99%) of the number of shares of the Common
Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of the Warrant.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">We sold the Securities to the Selling Securityholders
pursuant to a Securities Purchase Agreement between us and the Selling Securityholders dated November 8, 2023, as more fully described
in this prospectus (the &ldquo;Purchase Agreement&rdquo;). See &ldquo;Recent Developments &ndash; Sale of Common Stock and Warrants&rdquo;
for a description of the Purchase Agreement and the Securities and the &ldquo;Selling Securityholders&rdquo; for additional information
regarding the Selling Securityholders. The prices at which the Selling Securityholders may sell the Common Stock will be determined by
the prevailing market price for the shares or in negotiated transactions.</P>

sale of the Common Stock or Warrants owned by the Selling Securityholders but we will receive any proceeds from the exercise of the Warrants
for cash. Each Warrant entitles the holder thereof to purchase two shares of our Common Stock at a price of $0.60 per share (the &ldquo;Warrant
Exercise Price&rdquo;). If the price of our Common Stock remains below the Warrant Exercise Price, holders of the Warrants will be unlikely
to cash exercise their Warrants, resulting in no cash proceeds to us. See &ldquo;Use of Proceeds&rdquo; beginning on page 14 of this prospectus.
We will bear all costs, expenses and fees in connection with the registration of these securities, including with regard to compliance
with state securities or &ldquo;blue sky&rdquo; laws. The Selling Securityholders will bear all commissions and discounts, if any, attributable
to their sale of securities. See &ldquo;Plan of Distribution&rdquo; beginning on page 19 of this prospectus.</P>

of our total outstanding Common Stock as of the date of this prospectus. The Resale Shares being offered for resale in this prospectus
represent approximately 38% of our current total outstanding shares of Common Stock. The sale of all securities being offered in this
prospectus could result in a significant decline in the public trading price of our Common Stock.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Intrusion, Inc. is a cybersecurity company based
in Plano, Texas. We offer our customers access to our exclusive threat intelligence database containing the historical data, known associations,
and reputational behavior of over 8.5 billion Internet Protocol (&ldquo;IP&rdquo;) addresses. After years of gathering global internet
intelligence and working exclusively with government entities, we released <B>INTRUSION <I>Shield</I></B>, our first commercial product,
in 2021.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">For the fiscal years ended December 31, 2022 and
2021, we generated revenues of approximately $7,529,000 and $7,277,000, respectively, and reported net loss of approximately $16,229,000
and $18,802,000, respectively, and cash flow used in operating activities of approximately $13,190,000 and $16,557,000, respectively.
For the nine months ended September 30, 2023 and 2022, we generated revenues of approximately $4,245,000 and $6,085,000, respectively,
and reported net loss of approximately $11,074,000 and $11,035,000, respectively, and cash flow used in operating activities of approximately
$4,779,000 and $9,557,000, respectively. As noted in our unaudited financial statements, as of September 30, 2023, we had stockholders&rsquo;
deficit of $11,533,000 and working capital deficit of $14,813,000. As a result of our historical recurring losses from operations, negative
cash flows from operations, net working capital deficiency as well as our dependence on equity and debt financings, there is a substantial
doubt regarding our ability to continue as a going concern. See &ldquo;Risk Factors-We have a history of operating losses, our management
has concluded that there is substantial doubt about our ability to continue as a going concern and our auditor has included an explanatory
paragraph relating to our ability to continue as a going concern in its audit report for the fiscal years ended December 31, 2022 and
2021.&rdquo;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><B>INTRUSION <I>Shield</I>,</B> our newest cybersecurity
solution is a Zero Trust reputation-based Security-as-a-Service (&ldquo;SaaS&rdquo;) solution that inspects and kills dangerous network
(in and outbound) connections. What makes our approach unique is that <B>INTRUSION <I>Shield</I></B> evaluates every packet and analyzes
the IP addresses (source and destination), as well as domain information and the ports utilized and, when combined with other threat intelligence
data reports, blocks malicious connections. Many breaches today are caused by Zero-Day and malware free compromises that may not trigger
alarms in a traditional firewall or endpoint solution. <B>INTRUSION <I>Shield</I></B>&rsquo;<I>s</I> capabilities are designed to continuously
evolve as the threats and landscape change over time. Unlike traditional industry approaches that rely heavily on signatures, complex
rules, and human factors mitigation, which malicious actors and nation states have learned to bypass, <B>INTRUSION <I>Shield</I></B><I>&rsquo;s</I>
proprietary architecture isolates and neutralizes malicious traffic and network flows that existing solutions are ill equipped to handle.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">In September 2022, we expanded the <B>INTRUSION
<I>Shield</I></B> product line to include the Shield Cloud and Shield End-Point solutions. The initial <B>INTRUSION <I>Shield</I></B>
offering released in early 2021, the Shield On-Premise solution, utilizes hardware and is placed behind a firewall in a data center. Shield
Cloud extends the effectiveness of the Shield On-Premise solution to Infrastructure as a Service (IaaS), Platform as a Service (PaaS),
SaaS and serverless resources in the public cloud. This product serves as a protective gateway to the cloud, providing both Zero Trust
access to, and protecting outbound connections from, virtual hosts and serverless functions within the cloud. Shield Endpoint helps protect
the network outside of the corporate enclave and data center to include protection for remote workers, mobile, and cloud devices. This
product brings the network protection of the Shield On-Premise to these remote user devices establishing a Zero Trust network, both for
intra-organization connectivity and external internet connectivity.</P>

uses several original patents to uniquely characterize and record all network flows. <B><I>Savant</I></B> is a network reconnaissance
and attack analysis tool used by forensic analysts in the DoD, Federal Government, and corporations with in-house threat research teams.
For example, <B><I>Savant</I></B> users can create various automated rules to inspect packets matching (or not) certain criteria such
as creating a rule to ensure the Source MAC address field in the Ethernet header and Source IP address from the IP header are always the
same, failing which could indicate MAC or IP Spoofing in progress. Similarly, threat investigators can create rules using regular expressions
to analyze multiple fields in the packet headers.</P>

dependent upon our proprietary technology. We principally rely on a combination of contractual rights, trade secrets and copyright laws
to establish and protect our proprietary rights in our solutions. In addition, we have received two patents. We have also entered into
non-disclosure agreements with our suppliers, resellers, and certain customers to limit access to and disclosure of our proprietary information.
There can be no assurance that the steps taken by us to protect our intellectual property will be adequate to prevent misappropriation
of our technology or that our competitors will not independently develop technologies that are substantially equivalent or superior to
our technology, although it would be extremely difficult to replicate the proprietary and comprehensive internet databases we have developed

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">We have entered into software and solution license
agreements with various suppliers. These license agreements provide us with additional software and hardware components that add value
to our cybersecurity solutions. These license agreements do not provide proprietary rights that are unique or exclusive to us and are
generally available to other parties on the same or similar terms and conditions, subject to payment of applicable license fees and royalties.
We do not consider any of the solution license, software, or supplier agreements to be material to our business, instead, they are complementary
to our business and offerings.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The market for network and data protection security
solutions is intensely competitive and subject to frequent introductions of new technologies, and potentially improved price and performance
characteristics. Industry suppliers compete in areas such as conformity to existing and emerging industry standards, interoperability
with networking and other cybersecurity solutions, management and security capabilities, performance, price, ease of use, scalability,
reliability, flexibility, features and technical support. Our principal competitors in the data mining and advanced persistent threat
market include Niksun, NetScout, and Darktrace.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">There are numerous companies competing in various
segments of the data security market. At this time, we have little or no competitors for <B><I>TraceCop</I></B>; however, we believe competitors
could emerge in the future. These competitors currently perform only a portion of the functions that we can perform with <B><I>TraceCop</I></B>.
We have been continuously collecting the <B><I>TraceCop</I></B> data for more than twenty years, and we believe that none of our current
or future competitors will have the ability to provide and reference this historical data. In our newest market segment, data mining and
advanced persistent threat detection, we compete directly and indirectly with companies and open-source technologies in the firewall,
intrusion detection and prevention, anti-virus, network analysis, endpoint protection, and insider threat prevention areas of cybersecurity
technology.</P>

to the government, and we intend to market <B>INTRUSION <I>Shield</I></B> not only to our long-standing governmental customer base but
to expand our efforts to include more traditionally administrative and civilian governmental entities. Sales to government clients present
risks in addition to those involved in sales to commercial customers that could adversely affect our revenues, including potential disruption
due to irregularities in or interruptions to appropriation and spending patterns, delays in approving a federal budget and the government&rsquo;s
reservation of the right to cancel contracts and purchase orders for its convenience.</P>

Our customers, including government customers, may cancel their orders or contracts with little or no prior notice and without penalty.
Although we transact business with various government entities, we believe that the cancellation of any order in itself could have a material

    the date of issuance. The exercise price of the Warrants is $0.60 per share, subject to adjustments as set forth in the Warrant. The
    Warrants may be exercised by means of a &ldquo;cashless exercise&rdquo; at the holder&rsquo;s option, such that the holder may use
    the appreciated value of the Warrants (the difference between the market price of the underlying shares of Common Stock and the
    exercise price of the underlying the Warrants) to exercise the Warrants without the payment of any cash. We will not effect any
    exercise of the Warrants, and a Selling Securityholder shall not have the right to exercise any portion of the Warrant, to the
    extent that after giving effect to such issuance after exercise of the Warrant, the Selling Securityholder (together with their
    affiliates, and any other persons acting as a group together with the holder or any of their affiliates would beneficially own in
    excess of 4.99% (or, upon election by a holder prior to the issuance of any Warrants, 9.99%) of the number of shares of the Common
    Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon exercise of the Warrant.

    <TD>&nbsp;</TD>
    <TD STYLE="text-align: justify"><FONT STYLE="font-size: 10pt">We will receive the proceeds from any exercise of the Warrants for cash. Each Warrant entitles the holder thereof to purchase two shares of our Common Stock at a price of $0.60 per share (the &ldquo;Warrant Exercise Price&rdquo;). If the price of our Common Stock remains below the Warrant Exercise Price, holders of the Warrants will be unlikely to cash exercise their Warrants, resulting in no cash proceeds to us. However, the Warrants may be exercised on a cashless basis, in which case we would not expect to receive any gross proceeds from the cash exercise of the Warrants. Also, we will not receive any of the proceeds from the disposition and/or resale of the shares of Common Stock by the Selling Securityholders or their transferees. While we retain broad discretion on the use of proceeds, we intend to use such proceeds for working capital and general corporate purposes. The amounts that we actually spend for any specific purpose may vary significantly, and will depend on a number of factors including, but not limited to, market conditions.

of the Warrants will be unlikely to cash exercise their Warrants, resulting in no cash proceeds to us. Assuming the exercise of all Warrants
for cash, we will receive $5,231,249&nbsp; in gross proceeds at the Warrant Exercise Price, which amount is used solely for purposes of
estimating the gross proceeds we may receive upon exercise of those Warrants. However, the Warrants may be exercised on a cashless basis,
in which case we would not expect to receive any gross proceeds from the cash exercise of the Warrants. While we retain broad discretion
on the use of proceeds, we intend to use such proceeds for working capital and general corporate purposes. The amounts that we actually
spend for any specific purpose may vary significantly, and will depend on a number of factors including, but not limited to, market conditions.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">On November 8, 2023, we entered into a Securities
Purchase Agreement (the &ldquo;Purchase Agreement&rdquo;) pursuant to which, among other things, we sold to the Selling Securityholders,
in a private offering (the &ldquo;Offering&rdquo;), an aggregate of 4,359,374 shares of Common Stock (the &ldquo;Shares&rdquo;), each
of which was coupled with a warrant to purchase two shares of Common Stock (the &ldquo;Warrants&rdquo;), at an aggregate offering price
of $0.60 per share and warrant (the &ldquo;Purchase Price&rdquo;). Wellington Shields &amp; Co. LLC (the &ldquo;Placement Agent&rdquo;)
acted as placement agent in the Offering. Each Warrant is exercisable at an exercise price of $0.60 per share of Common Stock. The exercise
prices for the Warrants are subject to adjustment for stock splits, reverse stock splits, stock dividends and similar transactions. The
Warrants are exercisable from the date of issuance through the five-year anniversary of such date. In the event that there is no effective
registration statement registering the shares underlying the Warrants, then the Warrants may be exercised by means of a &ldquo;cashless
exercise&rdquo; at the holder&rsquo;s option, such that the holder may use the appreciated value of the Warrants (the difference between
the market price of the underlying shares of Common Stock and the exercise price of the underlying Warrants) to exercise the Warrants
without the payment of any cash. See &ldquo;Prospectus Summary - Recent Developments - Recent Sale of Common Stock and Warrants.&rdquo;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Warrants and the shares of Common Stock issued
pursuant to the Purchase Agreement were sold and issued without registration under the Securities Act of 1933, in reliance on the exemptions
provided by Section 4(a)(2) of the Securities Act as a transaction not involving a public offering and Rule 506 promulgated under the
Securities Act as sales to accredited investors.</P>

or 9.99%, as applicable, of our then outstanding common stock following such exercise, excluding for purposes of such determination shares
of common stock issuable upon exercise of such warrants which have not been exercised. The number of shares in the table below do not

asset or stock sale, or other transaction or series of transactions together resulting in a financial benefit to the interested stockholder.
An interested stockholder is a person who, together with affiliates and associates, owns or, within three years prior to the determination
of interested stockholder status, did own 15% or more of a corporation&rsquo;s outstanding voting stock. We expect the existence of this
provision to have an anti-takeover effect with respect to transactions our board of directors does not approve in advance. We also anticipate
that DGCL Section 203 may also discourage attempts that might result in a premium over the market price for the shares of Common Stock
held by stockholders.</P>

General Corporation Law (&ldquo;DGCL&rdquo;), a Director of the Corporation shall not be personally liable to the Corporation or its Stockholders
for monetary damages for breach of fiduciary duty as a Director, except for liability: (1) for any breach of the Director's duty of loyalty
to the Corporation or its Stockholders; (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing
violation of law; (3) under Section 174 of the DGCL; or (4) for any transaction from which the Director derived an improper personal benefit.
If the DGCL or other applicable provision of Delaware law hereafter is amended to authorize further elimination or limitation of the liability
of Directors, then the liability of a Director of this Corporation, in addition to the limitation on personal liability provided herein,
shall be limited to the fullest extent permitted by the DGCL or other applicable provision of Delaware law as amended. Any repeal or modification
of this Section 2 by the Stockholders of this Corporation shall be prospective only and shall not adversely affect any limitation on the
personal liability of a Director of the Corporation existing at the time of such repeal or modification. Our restated certificate of incorporation,

Law authorizes a corporation to indemnify its directors and officers against liabilities arising out of actions, suits and proceedings
to which they are made or threatened to be made a party by reason of the fact of their prior or current service to the corporation as
a director or officer, in accordance with the provisions of Section 145, which are sufficiently broad to permit indemnification under
certain circumstances for liabilities arising under the Securities Act of 1933, as amended (the &ldquo;Securities Act&rdquo;). The indemnity
may cover expenses (including attorneys&rsquo; fees) judgments, fines and amounts paid in settlement actually and reasonably incurred
by the director or officer in connection with any such action, suit or proceeding. Section 145 permits corporations to pay expenses (including
attorneys&rsquo; fees) incurred by directors and officers in advance of the final disposition of such action, suit or proceeding. In addition,
Section 145 provides that a corporation has the power to purchase and maintain insurance on behalf of its directors and officers against
any liability asserted against them and incurred by them in their capacity as a director or officer, or arising out of their status as
such, whether or not the corporation would have the power to indemnify the director or officer against such liability under Section 145.</P>
