CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Aikido Container Image Scanning
Teams shipping containers at scale across multiple registries need Aikido Container Image Scanning because its reachability analysis cuts false positives by actually determining which CVEs can execute in your environment, not just flagging every known vulnerability. The tool scans Kubernetes workloads directly and integrates with 12 major registries including ECR, GCR, and Artifactory, with AutoFix generating pull requests to patch real risks automatically. Skip this if your organization runs fewer than 50 container images monthly or needs runtime threat detection alongside build-time scanning; Aikido stops at the image layer and doesn't monitor what happens after deployment.
Teams protecting multi-tenant Kubernetes clusters on a zero budget will find k-rail's policy-as-code approach genuinely useful for blocking privilege escalation and enforcing network segmentation without vendor lock-in. The 441 GitHub stars and sustained community maintenance signal it actually works in production environments, not just in labs. Skip this if you need active vendor support or are already standardized on a commercial policy engine; k-rail is stable but no longer under active development, making it a solid option only for teams comfortable maintaining their own Kubernetes security controls.
