Falco Runtime Security

Falco is an open-source runtime security engine that monitors system calls and Kubernetes events to detect suspicious activity (data exfiltration, unauthorized privilege escalation, container breakout attempts). It sits inside the kernel (eBPF), watching every syscall with near-zero overhead. Used by 100k+ organizations for container and Kubernetes security. Senior Falco architects earn 25-35% premium because they design rules that catch real threats without false-positive noise. Mastery takes 4-6 weeks for basics, 2+ years for production expertise. The skill opens security ops, incident response, and compliance roles.
