Strategic acquisition will accelerate product-driven revenue and scale advanced cybersecurity solutions for leading enterprises

Booz Allen Hamilton (NYSE: BAH) today announced that it has entered into a definitive agreement to acquire Defy Security as a wholly owned subsidiary. Together, Defy Security and Booz Allen’s global commercial business will deliver end-to-end, tech-enabled cybersecurity solutions and products for U.S. and international enterprises in financial services, health and life sciences, manufacturing, technology, energy, retail, and beyond.

Defy Security’s strong customer base, sales expertise, and vendor relationships will complement Booz Allen’s deep industry knowledge and advanced tradecraft capabilities across commercial and federal markets. The combination will help accelerate and scale the company’s ability to deliver cyber products and services—such as Booz Allen’s AI-powered malware analysis product Vellox Reverser™—while preserving rigorous security, compliance, and oversight standards.

The acquisition will also support Booz Allen’s growing business in the United Kingdom and European Union, providing a broader international customer base with access to advanced cyber services.

“This acquisition helps us deliver resilient cybersecurity services and technologies for leading enterprises like never before,” said Andrew Turner, executive vice president and head of Booz Allen’s global commercial business. “Together Booz Allen and Defy Security will unlock new market opportunities, accelerate innovation, and help our customers protect their most critical assets in an increasingly fast-paced threat environment.”

Defy Security is headquartered near Pittsburgh, Penn., with an additional location in San Ramon, Calif. The company employs approximately 100 experienced cyber engineers, solution architects and salespeople.

"We founded Defy Security to reimagine the way commercial enterprises buy and scale cyber technology,” said Justin Domachowski, founder and CEO of Defy. “Combining Booz Allen’s deep technical qualifications and global reach with our leading cyber solutions and talent opens incredible opportunities to support global customers in new ways. We could not be more excited about the road ahead.”

The transaction is expected to close in the first quarter of Booz Allen’s fiscal year 2027 and is subject to customary closing conditions and regulatory approvals. Terms of the transaction were not disclosed.

Booz Allen retained AGC Partners as exclusive financial M&A advisor, PwC as accounting and tax advisor, King & Spalding as legal advisor, and Oliver Wyman for strategic industry advisory services. Defy Security retained J.P. Morgan Securities LLC as exclusive financial advisor and Choate, Hall & Stewart LLP as legal advisor. Defy Security is backed by Sverica Capital, a technology-focused private equity firm that partners with management teams to scale lower middle-market companies into industry leaders.
