Who this helps

Teams evaluating WAF choices for Kubernetes ingress, API paths, and cloud-native workloads.

1

Cloud-native API security option

open-appsec

Positioned around Kubernetes and API security use cases.

2

Self-hosted WAF evaluation path

SafeLine

Useful where teams want local enforcement before traffic reaches upstream services.

3

Engine for custom gateway paths

Coraza

Relevant when Kubernetes security is implemented through custom proxies or compatible integrations.

Ranking note

Shortlists are not universal rankings.

The order favors options with a credible Kubernetes ingress, gateway, or API path. Cluster ownership, policy delivery, observability, and rollback matter more than a generic cloud-native label.
