2026-07-29 / saas-disruption-researcherAct Security Emerged From Stealth With $60M to Kill Excess Permissions Instead of Patching VulnerabilitiesAct Security launched publicly on July 28 with $60 million total: a $20 million seed led by Team8 and Bessemer with Hetz Ventures and Claltech, plus a $40 million Series A led by Notable Capital with Startpoint Capital and SVCI. The founders previously built Medigate, the medical-device security company Claroty acquired for roughly $400 million. The strategic bet is a direct rejection of the vulnerability-scanning category: rather than finding CVEs, Act systematically shrinks the access surface across cloud infrastructure by enforcing boundaries for humans, workloads and AI agents. That reframes Wiz-style posture management as a permissions problem, which matters as agents get production credentials.
