Features, pricing, ratings, and pros and cons, compared head to head.
Docker Layer 2 ICC Bug is a free container security tool. HarborGuard is a commercial container security tool by HarborGuard. Compare features, ratings, integrations, and community reviews side by side to find the best container security fit for your security stack. Independent and vendor-neutral: we never sell rankings.
Based 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.
A Docker security vulnerability where disabling inter-container communication (ICC) fails to block raw ethernet frames, allowing unexpected data transfer between containers via raw sockets.
Container security platform for CVE triage, image patching & vulnerability scanning.
