                     INTRUSION INC. RECEIVES DELISTING NOTICE


RICHARDSON, Texas--(BUSINESS WIRE)--Aug. 20, 2002-Intrusion Inc. (Nasdaq:INTZ),
("Intrusion" or the "Company"), today announced that it has received
notification from the NASDAQ Stock Market, Inc. indicating that the Company
failed to comply with the minimum bid price requirements for continued listing
set forth in Marketplace Rule 4450(a)(5), and that its securities are,
therefore, subject to delisting from The Nasdaq National Market.  The letter
states that the Company will have until November 11, 2002 to regain
compliance.  If the bid price of the Company's common stock closes at $1.00
per share or more for a minimum of 10 consecutive trading days prior to
November 11, 2002, the Nasdaq staff will provide written notification that the
Company is in compliance.

If the Company is unable to regain compliance prior to November 11, 2002, it
may apply for listing on The Nasdaq SmallCap Market, which, if approved, makes
available a 180 calendar day SmallCap Market grace period, or until February
10, 2003 to regain compliance.  The Company will also then be eligible for an
additional 180 calendar day grace period, or until August 7, 2003 to
demonstrate compliance provided that it meets additional Nasdaq listing
criteria for the SmallCap Market.  Furthermore, the Company may be eligible to
transfer back to The Nasdaq National Market if, by August 7, 2003, its bid
price maintains the $1.00 per share requirement for 30 consecutive trading
days and it has maintained compliance with all other continued listing
requirements.
