Sealed Secrets is a free container security tool. Trend Micro Container Security is a commercial container security tool by Trend Micro. Compare features, ratings, integrations, and community reviews side by side to find the best container security fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
Trend Micro Container Security
Teams running Kubernetes in regulated industries should pick Trend Micro Container Security for its policy-based admission control paired with runtime drift detection, which catches both misconfiguration and active compromise in the same workflow. The platform covers NIST ID.RA through DE.AE, meaning it handles risk assessment and continuous monitoring without leaving gaps between what's approved at deploy time and what actually runs. Skip this if you need deep integration with existing SIEM tooling or if your team lacks Kubernetes expertise; the admission control policy syntax rewards operators who already think in Kubernetes primitives.
