OPA

OPA, or Open Policy Agent, is a software tool that helps organizations define, enforce, and manage policies across various systems and applications. It acts as a centralized decision engine where policies—rules about who can do what—are written in a standard language. When an application needs to check if an action is allowed, it consults OPA for a decision, ensuring consistent and automated policy enforcement. This streamlines compliance, enhances security, and makes it easier to adapt rules without changing the underlying applications.
