Booz Allen Hamilton announced it has completed its acquisition of Defy Security, a move aimed at strengthening its advanced cybersecurity offerings amid a rapidly evolving threat landscape.
The deal, which had been previously announced in February 2026, brings together Defy Security’s cybersecurity technology products, enterprise customer base, and vendor ecosystem with Booz Allen’s expertise across commercial and federal cyber missions. Defy serves clients across financial services, healthcare, manufacturing, and retail sectors.
By integrating capabilities, Booz Allen plans to expand delivery of end-to-end, tech-enabled cyber solutions across U.S. and international markets. A key component of this strategy includes its AI-native cyber product suite Vellox, which combines machine-speed automation with models trained by experienced cyber operators to respond to increasingly sophisticated threats.
Defy Security will initially operate as a wholly owned subsidiary of Booz Allen.
Booz Allen worked with AGC Partners as financial advisor, PwC as accounting and tax advisor, King & Spalding as legal advisor, and Oliver Wyman for strategic advisory. Defy Security was advised by J.P. Morgan Securities LLC and Choate, Hall & Stewart LLP. The company is backed by Sverica Capital.
