What is the best eBPF security tool for Kubernetes? For detection-only, Falco. For detection plus enforcement, Tetragon or KubeArmor. For full-stack correlation across cloud, Kubernetes, container, and application layers, ARMO CADR. The right choice depends on whether you need basic visibility, policy enforcement, or complete attack story generation that reduces investigation time by 90%+. Why do most eBPF security tools fail teams? They create more alerts, not better understanding.
