Press Releases

CHELMSFORD, Mass., June 13, 2013 (GLOBE NEWSWIRE) -- Mercury Systems, Inc. (Nasdaq:MRCY) (www.mrcy.com), a best-of-breed provider of commercially developed, open sensor and Big Data processing systems for critical commercial, defense and intelligence applications, announced that its Mercury Commercial Electronics facility in West Caldwell, NJ, received a Superior security rating in a recent vulnerability assessment conducted by the Defense Security Service (DSS). This Superior rating, the highest level awarded to cleared defense contractors by DSS, represents a two-level improvement from the facility's previous rating, and follows on the heels of Superior ratings already received at Mercury's headquarters facility in Chelmsford, Massachusetts and its Mercury Commercial Electronics facility in Salem, New Hampshire.

"Safeguarding information essential to the protection of our warfighters is a top priority, and at Mercury, we are committed to constantly identifying ways to improve our already superior security processes," said Tony Pospishil, General Manager of Mercury's RF and Microwave Subsystems group. "This Superior rating is a significant achievement that demonstrates our employees' complete dedication to national security and our strict compliance in protecting our technology and information."

A Superior rating is reserved for contractors that consistently and fully implement the requirements of the National Industrial Security Program Operating Manual in an effective fashion, resulting in a security posture that is superior to other contractors of similar size and complexity. The facility must have documented procedures that heighten the security awareness of employees and foster a spirit of cooperation within the security community. Currently, less than 8% of the approximately 13,000 facilities that the DSS oversees receive a Superior rating.
