Aqua Security Holistic Kubernetes Security vs Sealed Secrets: Side-by-Side Comparison (2026)

Sealed Secrets

Teams running Kubernetes who need to stop storing plaintext secrets in Git will find Sealed Secrets invaluable because it encrypts secrets at rest using asymmetric cryptography tied to each cluster, making accidental commits harmless. With 8,956 GitHub stars and adoption across thousands of clusters, the tooling is battle-tested and the encryption implementation is auditable. Skip this if you need secrets management across multiple clusters or cloud providers; Sealed Secrets' per-cluster key design forces operational overhead that centralized vaults like Vault or native cloud secret managers handle more elegantly.
