Press Releases

CHELMSFORD, Mass., August 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 Hudson, N.H., 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, Mass., its Mercury Commercial Electronics facilities in Salem, N. H. and West Caldwell, N. J., as well as a recent Commendable rating received by its Mercury Commercial Electronics facility in Manteca, Calif.

"The rating from DSS underscores our teams' dedication and commitment to safeguarding sensitive information and signifies the high level of trust the U.S. government places with Mercury," said Anthony Sweeney, General Manager of Mercury's RF and Microwave Components group. "At Mercury, we believe that securing and protecting information crucial to those serving our Nation is a tremendous responsibility, and we're proud to receive this recognition."

A Superior rating is awarded to 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.
