Defy Security & Bishop Fox

Defy Security and Bishop Fox bring Defy customers best-of-breed offensive security, delivered through a partner they already trust.

Defy Security was founded in 2017 to change how enterprises buy cybersecurity. Defy focuses only on cybersecurity and builds long-term relationships rather than one-off sales. It works with more than 450 cybersecurity vendors. Defy evaluates each partner to understand its capabilities, strengths and limits, so it can recommend complete solutions tailored to each customer’s environment.

Defy represents its customers in every partner engagement. It simplifies complex projects, reduces friction and supports long-term security work. Through Defy LABS, its test and validation lab, Defy’s engineers run proofs of concept and check how new solutions will perform before customers commit.

In 2026, CRN named Defy to its Tech Elite 250 list, and Defy won Gold for Service Provider of the Year in the Cybersecurity Excellence Awards. Defy Security is now a wholly owned subsidiary of Booz Allen Hamilton.
