Hadrian

External attack surface management platform testing exposures the way an attacker would.

Hadrian continuously discovers an organization's internet-facing assets and probes them offensively, using AI to chain findings the way a real attacker would rather than just flagging open ports. The result is a validated, prioritized view of external risk. Founded in 2021 in Amsterdam, it serves European and global enterprises.
