Computer security company to expand again


Trusted Information Systems, one of western Howard County's three largest employers and an international leader in computer security, is expanding again.

The company, which started in the Glenwood home of founder and President Stephen T. Walker, has outgrown its office building on Route 97 and is constructing an identical building.

Mr. Walker, a former computer security expert with the National Security Agency and the Pentagon, started his company with a single worker in 1983.

In little more than a decade, he had more than 100 employees and offices in Los Angeles, San Francisco and London.

Construction of the two-story office building began last month and is scheduled to be finished by Feb. 1.

It is being built behind the old building, which was constructed in 1987.
