Open Policy Agent

Role in IAAI Architecture

OPA (Open Policy Agent) is a CNCF policy-as-code engine serving as a core component of Pillar A's shared policy authority, called at runtime by Pillar B retrieval filters, Pillar C output orchestration, and Pillar D monitoring workflows. OPA evaluates identity context and policy rules to produce authorization decisions across AI pipelines, microservices, and API gateways.
