Hadrian, a provider of an agentic AI-powered offensive security platform, has closed a $40m funding round to expand into new markets and strengthen its technical teams.

Forgepoint Capital International and SmartFin co-led the investment, with returning backers HV Capital, Motive Partners, Picus Capital and Oetker Ventures also taking part. The latest round lifts Hadrian’s total capital raised to $65m. The company plans to use the money to grow its presence in EMEA and the US, and to put more resources into its engineering and research functions.

The deal comes at a time when AI is reshaping how cyber attacks are carried out. Reports of AI agents breaking out of test environments and compromising corporate systems without human input have recently drawn widespread attention.

Hadrian’s platform aims to address this by letting organisations view their security posture from an attacker’s perspective. It maps a business’s digital footprint, uncovers risks and ranks what needs fixing first so teams can harden their external attack surface. People define the objectives and take the key decisions, while AI handles the work in between, delivering the round-the-clock coverage, repetition and speed that human teams cannot maintain alone.

The company claims to be the only vendor bringing continuous exposure management and agentic penetration testing together in a single platform. Its Atlas product constantly maps an organisation’s external attack surface and deploys specialised AI agents to confirm which exposures are truly exploitable. Its Nova product offers on-demand agentic pentesting that matches, and goes beyond, the standard of human testers.
