OPA (Open Policy Agent)

Open Policy Agent (OPA) is an open-source software tool that helps organizations define, enforce, and manage policies across their digital systems. Think of it as a centralized decision-maker that evaluates rules—such as who can access a resource or how data can be used—and ensures policies are consistently applied. OPA integrates with applications and infrastructure, providing a flexible way to automate compliance, security, and governance without modifying the core systems. It’s like having a smart gatekeeper that enforces policies efficiently and transparently across complex technology environments.
