<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt">This prospectus relates to
the offer and sale, from time to time, by the selling security holder identified in this prospectus, or their permitted transferees (the
&#8220;Selling Holders&#8221;), of up to 1,505,179 shares of our common stock, par value $0.01 per share (&#8220;common stock&#8221;),
including (i)&#160;up to 1,195,666 shares of common stock (&#8220;Advance Shares&#8221;) that we may, at our discretion, elect to issue
and sell to Streeterville Capital, LLC (the &#8220;Streeterville&#8221;) from time to time after the date of this prospectus, pursuant
to the Standby Equity Purchase Agreement, dated as of July 3, 2024, entered into by and between Intrusion, a Delaware corporation (the
&#8220;Company&#8221; or &#8220;Intrusion&#8221;) and Streeterville (the &#8220;SEPA&#8221;), (ii) 92,592 shares of common stock (the
&#8220;Streeterville Commitment Shares&#8221;) issued to Streeterville upon the effective date of the SEPA as consideration for its irrevocable
commitment to purchase shares of common stock at our direction, from time to time after the date of this prospectus, and (iii) 216,921
shares of common stock (the &#8220;Pre-Delivery Shares&#8221;) issued to Streeterville for the purchase price of $0.01 per share upon
the effective date of the SEPA as further consideration for its irrevocable commitment to purchase shares of common stock at our direction,
from time to time after the date of this prospectus, upon the terms and subject to the conditions set forth in the SEPA. Please see &#8220;<A HREF="#a_007">Selling Security Holders</A>&#8221; for additional information regarding the Selling Holders.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt">&#160;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 24.5pt">Under the SEPA, the Company
agreed to issue and sell to Streeterville, from time to time, and Streeterville agreed to purchase from the Company, up to $10 million
of the Company&#8217;s shares of common stock. The Company shall not affect any sales under the SEPA and Streeterville shall not have
any obligation to purchase shares of common stock under the SEPA to the extent that after giving effect to such purchase and sale the
aggregate number of shares of common stock issued under the SEPA together with any shares of common stock issued in connection with any
other related transactions that may be considered part of the same series of transactions, where the average price of such sales would
be less than $1.08 and the number of shares issued would exceed 19.99% of the outstanding voting common stock as of July 2, 2024 (the
&#8220;Exchange Cap&#8221;). Thus, the Company may not have access to the right to sell the full $10 million of shares of common stock
to Streeterville. In connection with the SEPA, we are registering herein 1,505,179 shares of common stock, which represents the maximum
amount of shares issuable under the SEPA assuming without obtaining approval of shareholders in accordance with Nasdaq&#8217;s &#8220;minimum
price rule&#8221;, and assuming beneficial ownership limitations under the SEPA, and is comprised of (i)&#160;92,592 Streeterville Commitment
Shares, (ii) 216,921 Pre-Delivery Shares, and (ii) 1,195,666 shares of common stock issuable pursuant to the SEPA. If the Company desires
to issue more than 1,208,001 shares of common stock at an average price per share that does not equal or exceed $1.08 (which represents
the lower of (i) the Nasdaq Official Closing Price (as reflected on Nasdaq.com) immediately preceding the date of the SEPA; or (ii) the
average Nasdaq Official Closing Price for the five trading days immediately precedent the date of the SEPA), it would be required to obtain
shareholder approval under the Nasdaq listing rules.</P>

were 6,040,009 shares of common stock outstanding, of which 4,515,539 shares were held by non-affiliates. Assuming a (i) Market Price
of $1.08, (ii) no beneficial ownership limitations, and (iii) the receipt of stockholder approval to exceed the Exchange Cap, if all of
the 1,505,179 shares offered for resale by the Selling Holders under the registration statement of which this prospectus forms a part
were issued and outstanding as of July 18, 2024, such shares would represent approximately 19.95% of the total number of shares of our
common stock outstanding and approximately 25.00% of the total number of outstanding shares of common stock held by non-affiliates after
giving effect to such issuances.</P>

Amount (as defined in the SEPA) during the three consecutive Trading Days immediately preceding an Advance Notice (as defined in the SEPA),

Period&#8221;). &#8220;Market Price&#8221; is defined as the lowest VWAP of the common stock on the Nasdaq during the Pricing Period.
The Advances are subject to certain limitations, including that Streeterville cannot purchase any shares that would result in it beneficially
owning more than 9.99% of the Company&#8217;s outstanding common stock at the time of an Advance (the &#8220;Ownership Limitation&#8221;)

obtained stockholder approval to issue in excess of the Exchange Cap in accordance with the rules of Nasdaq or such issuances do not require
stockholder approval under Nasdaq&#8217;s &#8220;minimum price rule.&#8221; With respect to each closing, ten percent (10%) of the aggregate
Purchase Price will be withheld by Streeterville and used to repurchase shares of the Company&#8217;s Series A Preferred Stock held by

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">We have agreed, at our expense, to prepare and
file with the SEC certain registration statements providing for the resale of shares of common stock, including this registration statement.
The resale, or expected or potential resale, of a substantial number of our shares of common stock in the public market could adversely
affect the market price for our shares of common stock and make it more difficult for you to sell your shares of common stock at times
and prices that you feel are appropriate. In particular, as a result of the SEPA, Streeterville is an &#8220;underwriter&#8221; as such
term is defined in Section&#160;2(a)(11) of Securities Act, and the SEPA contemplates that Streeterville expects to resell any shares
of common stock we may issue and sell pursuant thereto. Furthermore, we expect that, because there will be a large number of shares registered,
Streeterville will continue to offer such covered securities for a significant period of time, the precise duration of which cannot be
predicted. Accordingly, the adverse market and price pressures resulting from an offering pursuant to a registration statement may continue
for an extended period of time.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&#160;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><B><I>The issuances of additional shares of common stock under the
SEPA may result in dilution of holders of common stock and have a negative impact on the market price of the common stock.</I></B></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&#160;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Pursuant to the SEPA, we may issue and sell up
to $10 million worth of shares of common stock (&#8220;Advance Shares&#8221;) to Streeterville. The price at which we may issue and sell
shares is at 95% of the lowest daily VWAP of the common stock during the three trading days following a notice to sell to Streeterville.
Assuming that (a)&#160;we issue and sell the full $10 million worth of shares of common stock under the SEPA to Streeterville, (b)&#160;no
beneficial ownership limitations, and (c)&#160;the issue price for such sales is $1.08 per share, such additional issuances would represent
in the aggregate approximately 1,195,666 additional shares of common stock or approximately 16.5% of the total number of shares of common
stock outstanding as of the date hereof, after giving effect to such issuance. In addition, the Company issued 92,592 shares of common
stock (the &#8220;Streeterville Commitment Shares&#8221;) to Streeterville upon the effective date of the SEPA as consideration for its
irrevocable commitment to purchase shares of common stock at our direction, from time to time after the date of this prospectus. Furthermore,
the Company issued 216,921 shares of common stock (the &#8220;Pre-Delivery Shares&#8221;) to Streeterville for the purchase price of $0.01
per share upon the effective date of the SEPA as further consideration for its irrevocable commitment to purchase shares of common stock
at our direction, from time to time after the date of this prospectus. If the beneficial ownership limitation is not waived, we may issue
approximately 670,365, shares of common stock, or approximately 9.99% of the total number of shares of common stock outstanding as of
the date hereof, after giving effect to such issuance. The timing, frequency, and the price at which we issue shares of common stock are
subject to market prices and management&#8217;s decision to sell shares of common stock, if at all.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Upon effectiveness of this registration statement,
Streeterville may resell all, some or none of their shares of common stock beneficially owned by them from time to time in their discretion
and at different prices subject to the terms of the SEPA. As a result, investors will likely pay different prices for those shares, and
so may experience different levels of dilution (and in some cases substantial dilution) and different outcomes in their investment results.
Investors may experience a decline in the value of the shares they purchase as a result of future issuances by the Company, whether to
Streeterville or others at prices lower than the prices such investors paid for their shares. In addition, if we issue a substantial number
of shares to such parties, or if investors expect that we will do so, the actual sales of shares or the mere existence of the SEPA may
adversely affect the price of our common stock or make it more difficult for us to sell equity or equity-related securities in the future
at a desirable time and price, or at all.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The issuance, if any, of common stock would not
affect the rights or privileges of the Company&#8217;s existing stockholders, except that the economic and voting interests of existing
stockholders would be diluted. Although the number of shares of common stock that existing stockholders own would not decrease as a result
of these additional issuances, the shares of common stock owned by existing stockholders would represent a smaller percentage of the total
outstanding shares of common stock after any such issuance, potentially significantly smaller.</P>

common shares (the &#8220;Common Stock&#8221;) over the 30 consecutive trading days from August 14, 2023, through September 25, 2023,
had fallen below $1.00 per share, which is the minimum closing bid price required to maintain listing on the NASDAQ Capital Market under
Listing Rule 5550(a)(2) (the &#8220;Minimum Bid Requirement&#8221;). In accordance with NASDAQ Listing Rule 5810(c)(3)(A), the Company
had 180 calendar days to regain compliance with the Minimum Bid Requirement (the &#8220;Grace Period&#8221;), or until March 25, 2024,
subject to a potential 180 calendar day extension. To regain compliance, the closing bid price of the Company&#8217;s Common Stock must
be at least $1.00 per share for a minimum of 10 consecutive business days within the Grace Period. On March 26, 2024, the Company received
an additional notice from Nasdaq notifying the Company that the Company had not regained compliance with the Minimum Bid Requirement and
is not eligible for a second 180-day period because the Company does not comply with the $5,000,000 minimum stockholders&#8217; equity
initial listing requirement for The Nasdaq Capital Market. Accordingly, this matter serves as an additional basis for delisting the Company&#8217;s
securities from The Nasdaq Stock Market. The notice also stated that the Hearings Panel (&#8220;Panel&#8221;) would consider the matter
in their discretion regarding the Company&#8217;s continued listing on Nasdaq and that the Company should present its views with respect
to this additional deficiency to the Panel in writing no later than 5:00 p.m. Eastern Time on April 2, 2024. On May 1, 2024, the Company
received written notice from the Listing Qualifications Staff of Nasdaq informing the Company that it has regained compliance with the
minimum bid price and equity requirements, respectively in Listing Rules 5550(a)(2) and 5550(b)(1) of the Nasdaq Stock Market as required
by the Panel&#8217;s decision previously reported. Accordingly, the Panel determined to continue the listing of the Company&#8217;s securities
on the Exchange and was closing the matter.</P>

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&#8217;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 (&#8220;DGCL&#8221;), a Director of the Corporation shall not be personally liable to the Corporation or its stockholders

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

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 &#8220;Securities Act&#8221;). The indemnity
may cover expenses (including attorneys&#8217; 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&#8217; 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>

SEPA, to require Streeterville to purchase a specified amount of shares of common stock by delivering written notice to Streeterville.
We will, in our sole discretion, select the amount of the advance that we desire to issue and sell to Streeterville in each Advance Notice
(as defined in the SEPA), subject to a maximum limit equal to the lesser of (i) an amount equal to 100% of the aggregate Daily Traded
Amount (as defined in the SEPA) during the three consecutive Trading Days immediately preceding an Advance Notice (as defined in the SEPA),
and (ii) 4.99% of the Company&#8217;s issued and outstanding common stock. The shares will be issued and sold to Streeterville at a per
share price equal to 95% of the Market Price for any three consecutive trading days commencing on the Advance Notice date (the &#8220;Pricing
Period&#8221;). &#8220;Market Price&#8221; is defined as the lowest VWAP of the common stock on the Nasdaq during the Pricing Period.</P>

Ownership Limitation&#8221;). The Beneficial Ownership Limitation may be waived by Streeterville as to itself and its affiliates upon
not less than 65 days&#8217; prior notice to us, on the terms and subject to the conditions set forth in the SEPA. However, the Beneficial
Ownership Limitation does not prevent Streeterville from selling some or all of the shares of common stock it acquires and then acquiring
additional shares, consequently resulting in Streeterville being able to sell in excess of the 9.99% Beneficial Ownership Limitation despite
not holding more than 9.99% of Intrusion&#8217;s outstanding shares of common stock at any given time. The Beneficial Ownership Limitation
was set as agreed to by the parties to the SEPA.</P>
