Don't Spend Three Months Choosing a Policy Engine

Reach for Gatekeeper and OPA when your policy problem is bigger than Kubernetes — Terraform, CI, Envoy, application authz — and you want one language across all of it. Reach for Kyverno when Kubernetes is the whole problem, when you want every engineer writing and reviewing policy rather than just the platform team, or when you need mutation, generation, or image provenance without standing up a second system. A lot of regulated shops land on both: Kyverno for the Kubernetes 80%, Rego kept for CI and infrastructure-as-code. But whichever you pick — don't spend three months choosing. The rules matter more than the engine, they are portable between the two, and the cost of picking the less ideal one is far lower than the cost of another quarter with no admission control at all.
