KyvernovsOpen Policy Agent

Kyverno addresses Kubernetes-native policy management. Kyverno's Kubernetes-native policy style is approachable for teams already comfortable with manifests and cluster resources. Admission control sits on a sensitive path. A bad policy can block releases, so dry runs and staged rollout matter.

Open Policy Agent addresses policy-as-code for cloud-native systems. OPA's strongest feature is portability: the same policy engine can be used for admission decisions and application authorization. Rego is expressive but not instantly approachable. Teams should budget time for tests and policy review.
