CST VerdictBased on our analysis of available product data, here is our conclusion:
Platform engineers debugging dropped traffic in Kubernetes clusters need kube-iptables-tailer because it surfaces iptables denials that your CNI and observability stack deliberately hide. The tool catches the networking friction that costs you hours in incident response, and it asks for nothing in return; 550 GitHub stars confirms adoption in production clusters where this signal gap matters. Skip this if your team runs service mesh with full request-level logging or if you're still on non-iptables network policies, since the value collapses when you already have that visibility layer.
Teams running microservices on Kubernetes who need runtime exploit detection without vendor lock-in will find Security-Guard valuable; it's free and open source, so you can audit the detection logic yourself and avoid subscription creep as you scale. The 67 GitHub stars and active community contributions show it's actually maintained, unlike many abandoned security projects. Skip this if you need integration with your existing SIEM or want a vendor to guarantee SLAs on detection accuracy; Security-Guard is a detection tool, not a managed security service.
