Features, pricing, ratings, and pros & cons — compared head-to-head.
Crypto4A QxVault™ is a commercial secrets management tool by Crypto4A. Sealed Secrets is a free secrets management tool. Compare features, ratings, integrations, and community reviews side by side to find the best secrets management fit for your security stack.
CST VerdictBased on our analysis of core features, integrations, here is our conclusion:
Enterprise teams with on-premises infrastructure and strict data residency requirements should evaluate QxVault primarily for its built-in FIPS 140-3 Level 3 HSM, which eliminates the need to procure and integrate a separate hardware module. The pending Level 3 validation and support for post-quantum cryptography algorithms address regulatory and future-hostile-algorithm risks that cloud-native vaults don't tackle at the hardware layer. Skip this if your organization is cloud-first and lacks the operational depth to manage HSM clustering and disaster recovery configurations, or if you need a secrets platform that also handles identity and access governance; QxVault deliberately stops at privileged 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.
