Intrusion’s net income was $41 thousand in the second quarter 2008 compared to a $0.5 million net loss for the second quarter 2007.

Revenue for the second quarter 2008 was $1.3 million compared to $1.0 million for the second quarter 2007.

Gross profit margin was 66 percent of revenue in the second quarter of 2008 compared to 61 percent of revenue in the second quarter of 2007.

 “Revenue increased 28%, gross profit margin increased from 61% to 66% and operating expenses decreased 31% in the second quarter of 2008 compared to the second quarter of 2007.  These positive achievements resulted in net income for the second quarter of 2008,” stated G.
