Company intelligence
As of July 28, 2026, Act Security has raised at least $60M in equity across 2 sourced funding rounds.
Action-centric cloud security platform that secures the access paths behind cloud and AI-agent breaches.
It was founded in 2025 by members of the team behind Medigate, the medical-device security company Claroty acquired for about $400 million.[1] The platform analyzes identity, network and AI access together and sets deterministic boundaries on what people, workloads and autonomous agents can reach.[1] It is built to remove exposed access pathways, limit AI agents to approved resources and continuously remove unused permissions.[1] Act also plugs into CI/CD pipelines to flag access violations before new applications or infrastructure reach production.[1] Its controls map to compliance frameworks including NIST 800-53, PCI DSS and HIPAA.[1] The seed round stayed undisclosed until the stealth launch.[2]
Langer has said close to 97% of cloud access sits dormant and unused, based on what the company sees from customers.[1]
