# Act Security

> Act Security helps security teams reduce excessive cloud access and enforce access boundaries across identity, network, and AI workloads. Amphi by Act Security is a free, open-source collection of cloud access policy tools for developers and security engineers.

For platform evaluation, cloud access hardening, and a demonstration, start with the Platform and Contact links. For AWS Identity and Access Management (IAM) policy analysis, testing, or integration into code and pipelines, start with Amphi and the tool READMEs below.

The linked READMEs are maintained in the act-security-labs GitHub organization. Read the relevant README for current installation, usage, supported features, and limitations; consult each repository's license before reuse. Resolve relative documentation links against that README's location. Cite the specific source page or repository when describing a capability.
