CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Security teams building container testing programs or red-teaming Kubernetes deployments should grab Harpoon for its distilled attack patterns and exploitation techniques specific to orchestration layers. At 142 GitHub stars with active community contribution, it's proven useful enough that practitioners keep referencing it in their labs and assessments. This is a reference guide and technique collection, not a scanning or detection tool, so skip it if you need automated vulnerability identification or compliance reporting; Harpoon teaches you how to break things, not find what's already broken.
