Supporting mission critical systems, services, and cyber security through innovation

The 21st century’s national security challenges have been largely driven by the explosive growth of digital communications and enterprise systems that have broken down the traditional barriers between information and the medium over which it was transmitted and archived. While the changing information technology environment provides many new opportunities, it also offers new threats.
