Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
DevOps teams shipping Helm charts through air-gapped or highly regulated environments need Helm GPG (GnuPG) Plugin because it's the only free option that bakes cryptographic verification directly into the chart deployment pipeline without external dependencies. The plugin integrates native GnuPG signing, meaning your chart provenance lives in the same key infrastructure your team already operates. This is a narrow fit: it solves chart authenticity for teams already managing GPG keys at scale; if your organization treats Helm as a convenience layer and hasn't invested in key governance, the operational overhead outweighs the security gain.
Startup security teams building fast without governance infrastructure should start with Ossprey, since its free tier removes cost friction and GitHub Actions integration means zero friction deployment. The tool maps dependencies and generates SBOMs on day one, covering the GV.SC and ID.AM functions that early-stage companies skip entirely. Ossprey's real strength is catching malicious packages before they land in your build; its weakness is in post-incident response and remediation workflows, so you'll still need a separate process for handling findings at scale.
