What if cybersecurity could think like a hacker

At Hadrian thats exactly what were building: the future of offensive cybersecurity powered by autonomous AI agents that think like hackers. Founded in Amsterdam in 2021 were on a mission to change the way organisations defend themselves by helping them find and fix security weaknesses before attackers can exploit them.

Our platform brings together two products: Atlas which continuously maps an organisations external attack surface and validates which exposures are genuinely exploitable and Nova which uses AI agents to perform in-depth penetration testing on demand. Together they give security teams the visibility and proof they need to focus on what really matters and stay ahead of emerging threats.

Backed by $65M in total funding including our recent $40M Series B led by Forgepoint Capital International and SmartFin were investing in the next generation of autonomous offensive security and expanding our impact across global markets. With a team spanning 25 countries and offices in Amsterdam London and New York were helping organisations rethink whats possible in cybersecurity.
