Open Policy Agent (OPA) is an open-source project that provides a flexible and powerful policy engine for cloud-native environments. OPA enables users to define and enforce policies across their infrastructure, applications, and services through a declarative language called Rego. OPA integrates seamlessly with popular tools and frameworks like Kubernetes, Istio, and Envoy, making it easy to implement fine-grained access control, security, and compliance policies.
