Booz Allen Hamilton finalizes acquisition of Defy Security to acale AI-driven cyber solutions

Booz Allen Hamilton (NYSE:BAH) announced on April 7, 2026, the successful completion of its acquisition of Defy Security, a move aimed at consolidating its position as a dominant provider of high-speed, tech-enabled cybersecurity services for both commercial and government sectors.

The closing of the transaction follows the initial merger agreement announced on February 17, 2026.

By integrating Defy Security’s extensive sales infrastructure and deep footprint in the financial services, healthcare, and manufacturing industries, Booz Allen aims to create an end-to-end "cyber powerhouse" capable of addressing the rapid evolution of AI-enabled threats.

A central component of the combined offering will be the deployment of Vellox™, Booz Allen’s AI-native cyber product suite.

The platform utilizes machine-speed automation and models informed by elite cyber operators to provide predictive defense capabilities.

The acquisition allows Booz Allen to scale these proprietary tools across Defy’s existing enterprise customer base, which includes several Fortune 500 retail and industrial firms.

Under the terms of the agreement, Defy Security—previously backed by the private equity firm Sverica Capital—will initially operate as a wholly owned subsidiary of Booz Allen.

Justin Domachowski, founder and CEO of Defy Security, noted that the partnership sets a "new standard" for enterprise security by merging Defy’s vendor ecosystem with Booz Allen’s decades of experience in complex federal cyber missions.
