The cloud‑security startup Act Security has secured $60 million to launch an action‑centric platform that protects enterprises from AI‑agent access risks in large‑scale cloud environments.

Act Security, a cloud‑security startup focused on AI‑agent threats, announced a $60 million Series B round to fund its action‑centric platform aimed at curbing agentic access sprawl across enterprise infrastructure.

Funding round and investors

The financing was led by Sequoia Capital with participation from existing backers Accel and Bessemer Venture Partners. The capital will support product development, go‑to‑market expansion, and hiring of security engineers.

Why agentic access sprawl matters

Enterprises increasingly deploy autonomous AI agents to automate tasks such as data processing, incident response, and resource provisioning. Without granular controls, these agents can accumulate permissions over time, creating a sprawling attack surface that traditional identity‑and‑access‑management tools struggle to monitor.

Act Security’s platform introduces an action‑centric model that ties each AI‑driven operation to explicit, auditable policies, allowing security teams to enforce least‑privilege principles at the infrastructure layer.

Key capabilities of the platform

  • Real‑time policy enforcement for AI‑initiated API calls
  • Automated detection of permission creep across cloud resources
  • Unified audit trail that maps actions back to originating agents
  • Integration with major cloud providers’ native IAM services

The solution is designed to work across multi‑cloud environments, supporting AWS, Azure, and Google Cloud, and can be deployed as a SaaS offering or on‑premises for highly regulated sectors.

Market impact and outlook

Analysts note that as AI agents become integral to cloud operations, demand for specialized security controls is expected to rise sharply. Act Security’s funding positions it to capture a growing niche that sits between traditional IAM and emerging AI‑risk management solutions.

The company plans to roll out beta access to several Fortune 500 customers later this year, with a broader commercial launch slated for early 2027.
