Booz Allen Hamilton has officially completed its acquisition of Defy Security, reinforcing its position in the rapidly evolving cybersecurity landscape. Initially announced on February 17, 2026, the deal now marks a strategic move to strengthen capabilities across both commercial and federal cyber missions.
With this acquisition, Booz Allen actively expands its reach by integrating Defy Security’s strong customer base, established sales infrastructure, and extensive vendor ecosystem. At the same time, the company leverages its own deep expertise in cybersecurity operations. As a result, the combined entity emerges as a powerful force designed to help organizations tackle increasingly sophisticated cyber threats.
Moreover, Defy Security brings significant experience in delivering cybersecurity technology products and services across industries such as financial services, healthcare, manufacturing, and retail. By combining these strengths, both companies aim to deliver comprehensive, end-to-end cyber solutions tailored to meet the demands of modern enterprises.
In addition, the integration enhances Booz Allen’s AI-driven capabilities. Notably, its AI-native cyber platform, Vellox™, will play a central role. This advanced solution blends machine-speed automation with models trained by expert cyber operators, enabling organizations to stay ahead of evolving threats and 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.
Furthermore, leadership from Defy Security expressed optimism about the partnership. “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.”
From an advisory standpoint, Booz Allen worked with AGC Partners as its exclusive financial M&A advisor, alongside PwC for accounting and tax advisory services. King & Spalding served as legal advisor, while Oliver Wyman provided strategic industry insights. Meanwhile, Defy Security partnered with J.P. Morgan Securities LLC as its financial advisor and Choate, Hall & Stewart LLP for legal counsel.
Importantly, Defy Security, backed by Sverica Capital, will initially operate as a wholly owned subsidiary of Booz Allen. This structure ensures continuity while enabling seamless integration and long-term growth.
Overall, this acquisition highlights Booz Allen’s commitment to advancing AI-powered cybersecurity innovation and delivering scalable, future-ready solutions across global markets.
