Falls Church-based contracting giant General Dynamics said today it will buy cybersecurity company Fidelis Security Systems, its fourth acquisition of the year.
Fidelis, which has about 70 employees at locations in Waltham, Mass. and Bethesda, provides software to help its users see the activity on their networks and better stop data breaches, according to General Dynamics.
General Dynamics has been one of the most actively acquiring contractors, hoping to protect the company’s profits even as federal spending shrinks and troops return from Iraq and Afghanistan.
The company has focused on areas it expects to grow, from healthcare services — it bought Arlington-based Vangent last year — to networking equipment — it picked up the parent company of IP Wireless earlier this year.
General Dynamics has also made buys focused on military equipment repair, which is expected to provide plenty of work as the Pentagon brings back weapons systems run down from years of war.
Fidelis will become part of General Dynamics’s Fairfax-based advanced information systems unit, which focuses on intelligence, surveillance and reconnaissance, the company said in its announcement.
