About:
Open Policy Agent (OPA) is an open-source, general-purpose policy engine that enables unified, context-aware policy enforcement across the stack. It decouples policy decision-making from application logic using a high-level declarative language called Rego. OPA helps developers and security teams codify and manage fine-grained access control, infrastructure security, and compliance policies.
|
Key Features:
- Declarative policy language (Rego) for complex rules
- Unified policy as code across microservices, CI/CD, and infrastructure
- High-performance evaluation with flexible deployment (sidecar, library, API)
- Rich tooling including a REPL, test framework, and bundle API
|
Use Cases:
- API authorization and fine-grained access control
- Infrastructure as Code (IaC) validation and Kubernetes admission control
- Data filtering and data governance enforcement
- CI/CD pipeline policy checks and compliance automation
|
Alternatives:
-
Cedar
– AWS's policy language focused on fine-grained authorization with a different language design and ecosystem
-
Styra DAS
– Enterprise control plane and managed service built around OPA for governance and lifecycle management
