AI Security Firm Hadrian Raises $40M Led by Forgepoint and SmartFin

The raise signals that venture money is still flowing to security tooling that treats AI agents as both a defensive instrument and part of the attack surface enterprises must map. It matters most to CISOs and security teams already juggling exposure management with limited headcount, since automated attacker-view simulation is pitched as a way to validate real risk rather than just enumerate findings. The open question is whether this category consolidates around a few platforms or stays crowded, and whether the participating backers' continued support translates into enterprise adoption beyond early buyers.
