Cloud Container Attack Tool (CCAT) is a free container security tool. Chainguard VMs is a commercial container security tool by Chainguard. 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:
Security teams validating their container defenses on AWS and GCP should use Cloud Container Attack Tool because it's free and built explicitly for adversary simulation rather than passive compliance scanning. With 646 GitHub stars and a zero-cost model, CCAT lowers the barrier to red-teaming your own container environments before attackers find the gaps. Skip this if you need managed remediation or policy enforcement; CCAT is a testing framework, not a runtime guard.
Teams running containerized workloads across AWS, GCE, or Azure will benefit most from Chainguard VMs if your priority is eliminating OS-level CVE risk before it enters your supply chain. The zero-CVE guarantee backed by a 7-day critical remediation SLA and continuous automated rebuilds means you're not patching; you're replacing. Skip this if you need application-layer runtime protection or behavioral threat detection, since Chainguard VMs optimize for asset hygiene (NIST ID.AM and PR.PS) but don't detect or respond to actual attacks in motion.
