INTRUSION INC. ANNOUNCES
FIRST QUARTER RESULTS

Richardson, Texas — May 14, 2009 — Intrusion Inc. (OTCBB: INTZ), (“Intrusion”) today announced financial results for the quarter ended March 31, 2008.

Revenue for the first quarter 2009 was $0.9 million, compared to $0.5 million for the first quarter 2008.

Intrusion’s operating loss was $0.3 million in the first quarter 2009, compared to $0.9 million for the first quarter 2008.

Gross profit margin was 68% of revenue in the first quarter of 2009; compared to 61% in the first quarter 2008.

Intrusion’s first quarter 2009 operating expenses were $0.9 million; compared to $1.2 in the first quarter 2008.

As of March 31, 2009, Intrusion reported cash and cash equivalents of $0.2 million, a working capital deficiency of $1.7 million and debt of $0.6 million.

“Revenue in the first quarter was reduced by slippage of contracts from the U.S. Government; however, since April 1, 2009, as previously reported, we have booked a total of $1,200,000 of new TraceCop orders from a U.S. Defense Prime Contractor.  These new TraceCop orders are expected to produce revenue over the second and third quarters of 2009,” stated G.
