About
Peraton is a national security and critical infrastructure technology company founded in 2017 through Veritas Capital's acquisition of Harris IT Services, headquartered in Herndon, Virginia. The company operates at the classified intersection of space, intelligence, cyber, defense, and civilian IT missions, generating over $8 billion in annual revenue with a workforce exceeding 17,000 cleared professionals.\n\nPeraton's portfolio covers space systems engineering, satellite communications, intelligence analysis, cybersecurity operations, digital transformation for federal agencies, and mission application development. The company has built deep experience supporting agencies such as NASA, NGA, NSA, DISA, and the military services. Its "enterprise IT at scale" strategy emphasizes complex, multi-year programs in the $500 million to $2 billion range—an area where its cleared workforce and program execution track record provide competitive advantages.\n\nFormed through the merger of Perspecta (a combination of DXC's government IT business, Vencore, and KeyW) and Northrop Grumman's IT and mission services division, Peraton rapidly became one of the largest pure-play national security IT contractors. Veritas Capital has positioned Peraton as a strategic consolidator in government IT, adding capabilities in autonomy, AI, and next-generation communications since 2021.
