Docker Layer 2 ICC Bug 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.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Teams running multi-tenant Docker environments who need to validate that inter-container isolation actually works should test Docker Layer 2 ICC Bug immediately; it exposes a real bypass in ICC enforcement that raw socket access creates, one that most container security tools and network policies silently miss. The 66 GitHub stars reflect active adoption among practitioners who've caught this in production, and the vulnerability remains unpatched in older Docker versions still in heavy use. Skip this if you're already using eBPF-based runtime monitoring or running only single-tenant clusters where container-to-container trust assumptions hold; this tool does one thing and doesn't prevent the vulnerability, only detects that it exists.
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.
