About ACT

Act Security (ACT) is a Tel Aviv cybersecurity company founded in 2025 by the Medigate founding team—Jonathan Langer (CEO), Itay Kirshenbaum (CTO), Stephen Goldberg (CPO) and Ilai Fallach (Chief R&D Officer)—that builds an action-centric cloud security platform to shrink the infrastructure access surface for humans, workloads and AI agents. Rather than flooding teams with vulnerability findings, Act enforces deterministic least-privilege boundaries by reasoning across identity permissions, network reachability and AI access together, using agentless native cloud controls, safe-audit simulation of policy changes, CI/CD guards against access sprawl and continuous compliance mapping to frameworks such as NIST and PCI DSS. The pitch targets dormant cloud permissions that AI agents can inherit and exploit at machine speed. Emerging from stealth in July 2026, Act announced $60 million in total funding: a $20 million seed led by Team8 and Bessemer Venture Partners with Hetz Ventures and Claltech, and a $40 million Series A led by Notable Capital with Startpoint Capital and SVCI.
