m9sweeper is a free container security tool. Plexicus Container Security is a commercial container security tool by Plexicus. Compare features, ratings, integrations, and community reviews side by side to find the best container security fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Platform teams managing multiple Kubernetes clusters on a budget will find m9sweeper valuable because it bundles industry-standard open source utilities into a working security baseline without vendor lock-in or licensing costs. The free model and 265 GitHub stars indicate active community validation for detecting misconfigurations and runtime policy violations across clusters. Skip this if you need commercial support SLAs or a UI-first experience; m9sweeper requires comfort with open source tooling and some manual integration work.
Teams building containerized applications on tight budgets should evaluate Plexicus Container Security for its runtime threat detection and automated response capabilities, which catch post-deployment attacks that image scanning alone misses. The platform covers the full shift-left-to-runtime arc with hardcoded secrets detection, CVE scanning, Kubernetes policy enforcement, and continuous monitoring, mapping to NIST ID.RA and DE.CM functions most buyers actually need. Skip this if you're looking for a broader CNAPP that handles cloud infrastructure or VMs; Plexicus stays focused on containers and Kubernetes, which is exactly why smaller teams without dedicated platform security engineers will move faster with it.
