About Kubewarden

Kubewarden is an open-source policy engine designed to simplify policy-as-code adoption within Kubernetes environments. It enables enterprises to write and enforce admission control policies using familiar programming languages such as Rust, Go, CEL, and Rego, compiled into portable WebAssembly modules. This approach eliminates the need to learn new domain-specific languages, allowing policy authors to leverage existing skills and tools.

Kubewarden integrates seamlessly with Kubernetes through custom resources and functions as an admission webhook, evaluating policies in isolated, secure sandboxes. Its policies are distributed via standard container registries, facilitating easy integration into existing CI/CD pipelines and infrastructure. Beyond Kubernetes, Kubewarden's adaptable architecture allows validation of any JSON document, extending its utility for broader cloud security use cases. This makes it particularly suitable for enterprises seeking flexible, vendor-neutral cloud security solutions that support policy portability and developer productivity.
