Falco is a cloud-native security tool that provides runtime security across hosts, containers, Kubernetes, and cloud environments. It uses customizable rules based on Linux kernel events and other data via plugins, powered by eBPF, to deliver real-time alerts for abnormal behavior, threats, and compliance violations. As an open-source CNCF-graduated project, Falco integrates with 50+ systems, deploys in Kubernetes (with Helm), and runs on x64 and ARM CPUs, enabling broad, real-time detection and easy alert forwarding to SIEMs and data lakes.
