Secrets Management

3 Best Sealed Secrets Alternatives in 2026

Sealed Secrets is a Kubernetes controller from Bitnami that lets you store encrypted secrets directly in Git. You use the kubeseal CLI to encrypt a regular Kubernetes Secret into a SealedSecret custom resource, which only the controller running in your cluster can decrypt. This makes secret material safe to commit, review, and diff in version control without a separate secrets manager.
