oscap-docker vs Chainguard: 2026 Comparison
oscap-docker is a free container security tool. Chainguard is a commercial container security tool by Chainguard. 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 compliance-heavy Docker deployments on tight budgets should reach for oscap-docker; it maps directly to NIST CSF Govern and DISA STIGs without licensing friction. The tool handles both image scanning and live container assessment using battle-tested OpenSCAP frameworks, giving you policy enforcement that actually matches your compliance checklist. Skip this if you need runtime threat detection or integration with a broader container platform; oscap-docker does compliance auditing well and vulnerability scanning acceptably, but it won't catch exploit attempts or container escapes in production.
