Act Security raises $60M to take action against agentic access sprawl at the infrastructure layer

What happened

Act Security, a cloud security startup founded last year, has raised a total of $60 million in funding over two rounds. The initial seed round brought in $20 million led by Team8 and Bessemer Venture Partners. The company focuses on preventing uncontrolled AI agent access across enterprise infrastructure by managing what it calls “agentic access sprawl.”

Why it matters

As organizations scale AI deployments, especially with autonomous agents running on infrastructure, managing permissions and access grows complex and risky. Act Security’s solution targets this blind spot in cloud environments where aggressive AI agents can create security gaps by requesting broad or inappropriate access. The sizable funding signals investor confidence that controlling AI agent access at the infrastructure layer is a critical need. Without tight controls, enterprises risk data leaks, compliance breaches, and operational disruptions as AI agents multiply. Act Security aims to plug this gap by offering enforceable guardrails that prevent agent overreach before damage occurs.

What to watch next

Watch for how Act Security’s platform integrates with existing cloud providers and AI development workflows. Its ability to balance secure access governance without slowing AI adoption will determine enterprise uptake. Also, monitor whether other cloud security vendors respond with similar agent-focused controls or try to embed this functionality into broader cloud security suites. The evolving operational model for trusted AI agents running at scale will be critical for IT teams juggling security and innovation.
