Richardson, Texas — May 10, 2016 — Intrusion Inc. (OTCQB: INTZ), (“Intrusion”) today announced financial results for the quarter ended March 31, 2016.

Intrusion’s net loss was $544 thousand in the first quarter 2016, compared to net loss of $310 thousand for the first quarter 2015.

Revenue for the first quarter 2016 was $1.51 million, compared to $1.71 million for the first quarter 2015.

Gross profit margin was 64% of revenue in the first quarter 2016; compared to 63% in the first quarter 2015.
