CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
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.
Teams running microservices on Kubernetes who need runtime exploit detection without vendor lock-in will find Security-Guard valuable; it's free and open source, so you can audit the detection logic yourself and avoid subscription creep as you scale. The 67 GitHub stars and active community contributions show it's actually maintained, unlike many abandoned security projects. Skip this if you need integration with your existing SIEM or want a vendor to guarantee SLAs on detection accuracy; Security-Guard is a detection tool, not a managed security service.
