Largest US Army site in the world more than doubles security project scope with addition of Intrusion
Prevention Capability to Block Network-based Attacks

Richardson, Texas – May 3, 2005 – Intrusion Inc.(NASDAQ: INTZ), (“Intrusion”) announced today it received an order, for $1.0 million, from the US Army at Fort Hood, Texas for its Common Criteria certified SecureNet Pro Network Intrusion Prevention/Detection system.  Approximately ninety percent of the revenue from this sale will be recognized in the second quarter 2005.  This latest purchase will enhance the Army’s capability to automatically block network-based intrusions from outside, internet-based attacks as well as internal exploits, often times referred to as back-door or Trojan attacks.

“Intrusion stepped up with the tools, training and tactics when the US Army at Fort Hood needed them,” stated LTC Edward J. Morris, Jr., Commander, 1114^th Signal Battalion and Director of Information Management (DOIM) at Fort Hood.  “Now, we’re ready to see, focus and act to eliminate the threat.”

Intrusion’s highly accurate SecureNet system is combined with an innovative Security Status Review (SSR) management process deployed by numerous Army sites to protect Department of Defense computers and networks from harmful intrusions, spyware infections and other malicious attacks.  The SecureNet family includes a full range of high-performance, network-based Intrusion Prevention/Detection sensors, Host-based Intrusion Prevention agents, spyware prevention signatures supported under the company’s SecureNet SpySnare offering and a comprehensive security management and forensics system, SecureNet Provider.

Ben A. Bittle, Intrusion Director of Product Management explained, “The engineering teams at Intrusion worked with Army personnel at Fort Hood to help execute the SecureNet battle plan required to protect the Army’s critical infrastructure.   We continue to appreciate the Army’s confidence in SecureNet and our SSR security support as we expand the Network Intrusion Prevention implementation at Fort Hood.”
