Hadrian

Outside-in autonomous hacker that discovers, exploits, and validates external exposure continuously.

Proof of life. Shipped Sense, Plan, Attack AI agents to operationalize CTEM, November 2025

Hadrian runs a Sense, Plan, Attack loop of hacker agents against the customer's internet-facing estate. The filter is supposed to be 100% validated, which is the only way an ASM feed becomes a CTEM program instead of another alert pile. Dutch origins show in the product: it behaves like a persistent pentest firm that never clocks out, not a port scanner with a dashboard.
