OPA solves the problem of defining and enforcing policies across a system. Some examples:
- How do I enforce that inbound API requests come only from trusted sources?
- How do I enforce fine-grained access to user records?
- How do I enforce a set of naming conventions for a data update?
Many such policies may come from regulatory requirements, may be regional in nature, and may change in otherwise stable codebases. And it's even harder when you're applying this to a highly-scalable production internet service. As a result, defining policy at an organizational level with auditing is a challenge for large enterprises. OPA helps enterprises administer and enforce policies.
