Continuing its expansion into the cyber security space, Raytheon [RTN] on Oct. 5 said it acquired Foreground Security, a provider of security operations centers, managed security service solutions and cyber security professional services.

Terms of the deal, which closed week of Sept. 28, were not disclosed.

Raytheon said the acquisition accelerates its expansion into managed security services across federal, international and commercial markets. A company spokeswoman told sister publication Defense Daily that Raytheon provided the managed security services while the acquisition added new capabilities and customers.

Foreground Security’s senior managers will stay with the company, which has been renamed Raytheon Foreground Security (RFS), for at least several years, the spokeswoman said.

“Foreground has a well-earned reputation for cutting edge, next-generation capabilities in security monitoring services and proprietary ‘cyber hunting’ technologies,” David Amsler, founder and CEO of Foreground Security, said in a statement. “And now as part of Raytheon, we will have the resources and breadth to build upon these advanced capabilities and bring them to a much larger global customer set.”

RFS has about 165 employees, with about 85 percent who are trained as cyber security experts, Raytheon said. Foreground brings its Virtual Security Operations Center and Automated Threat Intelligence Platform for cyber monitoring, threat hunting, and professional services.

On its website, RFS mentions the Departments of Health and Human Services, Homeland Security, and Blue Cross Blue Shield as current or previous customers.

Earlier this year Raytheon expanded its position in the commercial cyber security market with the purchase of a majority share in Websense.
