Privacy by Default with Open Policy Agent

Open Policy Agent (OPA) delivers that control. It is a unified policy engine that runs across your stack—Kubernetes, microservices, APIs, CI/CD, cloud. One policy language, Rego, defines the rules. You get consistency, no matter where those rules live.

Privacy by default with OPA means that the absence of an explicit allow is an automatic deny. It turns “secure-by-design” from a slogan into enforced behavior. New services don’t ship exposing private data by mistake. You can bind OPA to admission controllers in Kubernetes, reverse proxies for APIs, and policy checks in pipelines. It evaluates requests before they pass, blocking what violates your privacy baseline.

OPA decouples policies from code. That makes them easier to audit, update, and scale. Privacy rules stay visible, versioned, and testable. You can grant minimal privileges while still enabling collaboration. If a new endpoint appears, OPA applies your privacy-first defaults without waiting for a developer to notice.

Key principles of OPA privacy by default:

• Deny unless allowed by policy.
• Centralize rules in Rego for all environments.
• Embed enforcement into every service layer.
• Test policies automatically before deployment.

This model shuts down accidental exposure fast. It’s not about trusting developers to remember 50 checks—it’s about encoding those checks once and letting OPA execute them reliably everywhere.

You can deploy OPA as a sidecar, daemon, or library. Policies sync via GitOps or pipeline automation. Logs from OPA decisions give you clear audit trails. And because it’s open source, you have full control and transparency over your enforcement logic.

Set the rule: nothing leaves without permission. Make that the baseline. Privacy is not bolted on after—it comes built into every request, every resource, every service.
