The company concentrates on three core areas within the federal government—cyber security, intelligence surveillance and reconnaissance, and biometrics and identity intelligence. Based in Tysons, Virginia, the firm positions itself as a small provider serving intelligence agencies, the Department of Defense, and civilian government bodies. Its offerings are designed to support secure networks, intelligence collection, and identity assurance for federal programs. Within the defense and space manufacturing landscape, the company is characterized by its specialized focus on federal mission areas rather than broader commercial markets.
