CST VerdictBased on our analysis of available product data, 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.
Kubernetes security teams who need to validate their cluster defenses without waiting for vendor tooling will move fastest with MTKPI. It's a free Docker image pre-loaded with pentest essentials, so you skip procurement cycles and start testing within minutes; the 255 GitHub stars reflect active use in the community. Skip this if your team lacks Linux command-line fluency or needs guided remediation workflows; MTKPI is a sharp tool for practitioners, not a platform for junior analysts.
