ANNOUNCES

First quarter results

for fiscal 2007

Irving, Texas – November 15, 2006 – Integrated Security Systems, Inc. (OTCBB Symbol: IZZI) today announced improved results for the first quarter of fiscal 2007. Overall, sales for the security products manufacturer were up for the quarter year-over-year by over 20%. Much of the difference was attributable to significant increases in the road and bridge segment of the business combined with growth in the Intelli-Site software division.

Gross margin for the company also saw significant improvement from 27% for first quarter 2006 to 36% for the same period in fiscal 2007.  Much of the margin improvement is a direct result of restructuring of the B&B ARMR division which began in mid-2005 and involved the closure of the company’s manufacturing operations in Norwood, Louisiana. Performance was further enhanced by an operating expense decrease of 36% from the prior year. This improvement in overhead expense comes as a direct result of the restructuring. Operating losses for the company were cut by nearly 80% over the prior year first quarter.

“The restructuring of the company is clearly taking hold,” notes ISSI President and CEO Jay Foersterling. “We’ve made sweeping changes to the business to improve profitability, and it is obvious that those initiatives are succeeding.”

In summarizing the improvement made in the business over the last twelve months, Foersterling believes that the company is well positioned for future growth and profitability. “Our initial focus was on reducing costs while improving product quality and customer service,” states Foersterling.  “Now that we have made significant strides in those areas, our focus will be on driving top line growth.” Company management feels that the market dynamics in the core security and anti-terrorist barrier business have experienced significant change. According to Foersterling, “The security barrier business of a few years ago has matured. In the past, the emphasis was on installing anything that would stop a vehicle, regardless of how it looks or fits into the surrounding environment. Now, however, the focus has increasingly moved toward a combination of aesthetics, quality and value.  These are areas in which we excel.”

“While the Federal government still is a significant customer, we’re seeing improved opportunities in the state and local governmental sectors as well as in the industrial and commercial base, both domestically and abroad,” says Foersterling.  “These are markets highly oriented toward product performance and value; our competitive strengths.”
