Booz Allen Hamilton (NYSE: BAH) today announced it has completed its acquisition of Defy Security. The transaction was previously announced on February 17, 2026.
Defy provides cybersecurity technology products and services to leading financial services, healthcare, manufacturing, and retail enterprises. Combining its robust customer base, sales infrastructure, and vendor ecosystem with Booz Allen’s deep expertise in nearly all major commercial and federal cyber missions creates a new powerhouse to help customers combat accelerating cyber threats.
Together the companies will deliver highly competitive, end-to-end, tech-enabled cyber solutions across U.S. and international commercial and federal markets—including Booz Allen’s AI-native cyber product suite Vellox™, which pairs machine-speed automation with models trained by elite cyber operators to outpace adversaries.
“Today’s AI-enabled threat environment moves at unprecedented speed. Joined with Defy Security, we can help more enterprises around the world innovate ahead of pervasive cyber threats and protect their most critical assets,” said Andrew Turner, executive vice president and head of Booz Allen’s global commercial business.
“Booz Allen and Defy share a commitment to growth, collaboration, and technical excellence,” said Justin Domachowski, founder and CEO of Defy Security. “We look forward delivering tremendous value to customers together as we set a new standard for enterprise cybersecurity.”

Defy Security retained J.P. Morgan Securities LLC as exclusive financial advisor and Choate, Hall & Stewart LLP as legal advisor.
