Act Security Raises $60 Million and Launches Cloud Security Platform

Act Security announced in a press release that it has emerged from stealth with $60 million in total funding and launched a cloud security platform. The Tel Aviv company was founded in 2025 by the team behind Medigate.

The funding includes a $20 million seed round led by Team8 and Bessemer Venture Partners, with participation from Hetz Ventures and Claltech. Act also raised a $40 million Series A led by Notable Capital, with participation from Startpoint Capital and SVCI.

The platform is designed to reduce access paths across cloud infrastructure by enforcing boundaries for humans, workloads, and AI agents. Act said it reasons across identity, network, and AI access, and enforces controls through cloud controls and traditional controls that customers already use.

The company said the platform can remove exposed access paths, set defined access boundaries for AI workloads, reduce unused cloud permissions, and extend checks into CI/CD pipelines. It also maps perimeter and data boundary enforcement to controls required by NIST 800-53, PCI DSS, HIPAA, and other frameworks.
