About Sentar

Sentar is an employee-owned cyber-intelligence firm working from a Discovery Drive office in Cummings Research Park, with a 4.9 Google rating across 9 reviews. Founded in 1990, the firm has grown into one of the fastest-growing cyber-intelligence companies serving the national security sector, with a team of more than 300 cybersecurity, intelligence, and engineering experts.

Sentar blends cybersecurity, intelligence and analytics, and systems and software engineering, and it offers cybersecurity and IT managed services alongside its mission work. The firm became the first CMMC Third-Party Assessment Organization (C3PAO) headquartered in Alabama and has itself achieved CMMC Level 2 certification, a strong signal for defense clients navigating compliance.

Its client base centers on the Defense Health Agency, the U.S. Army, the U.S. Navy, and the Missile Defense Agency, so Sentar suits larger Huntsville contractors and agencies that want a mature, deeply credentialed partner for managed security and compliance rather than a small general-IT shop.
