General-purpose policy engine that decouples policy decision-making from application logic, using the Rego declarative language for policy-as-code across the stack.
Why it matters for NETEVO
OPA is the most-adopted general-purpose policy engine in the cloud-native stack. It decouples policy decision-making from application logic: policy is authored in the Rego declarative language and evaluated by the engine, separately from the services it governs. In agentic-AI architectures it serves, alongside AWS Cedar, as the runtime engine that consumes policy and returns ALLOW / DENY / OBLIGATE decisions per agent action. Any organisation running Kubernetes, microservices, or a modern cloud architecture is likely to have an OPA decision point somewhere in the stack already.
OPA pairs with Cedar and Catala as the policy-language triad that the Law-to-Code Methodology can target. Where Cedar emphasises formal analysability and Catala emphasises law-as-DSL fidelity, OPA / Rego emphasises operational ubiquity and cloud-native integration. The choice between the three is positional rather than absolute, and the Methodology itself is engine-agnostic.
OPA is anchored by an open-source project rather than a peer-reviewed paper. The stable reference is the project documentation at its canonical URL, and the project's versioned history is maintained through its GitHub releases.
Where NETEVO applies this
- Agent Infrastructure Whitepaper — load-bearing — Dimension 2 (policy-as-code); pair with Cedar
- AI Traffic Monetisation Whitepaper — the runtime decision point for an allow / charge / block per-crawler metering decision
Who acts on this
Reading this usually means something has forced the question — a listing, an audit finding, a procurement questionnaire, a regulator's letter. The role pages below set out what NETEVO does about it, including where we would tell you not to engage.
