/ About /

Cilium is an open-source networking, observability, and security solution for cloud-native environments, built on the eBPF Linux kernel technology. It provides high-performance networking and fine-grained security policies for Kubernetes and other container orchestration platforms. Cilium leverages eBPF to enable deep visibility and control over network traffic without requiring application code changes.

/ How it works /

Cilium uses eBPF technology to hook into the Linux kernel, enabling dynamic network policy enforcement, load balancing, and observability without modifying application code.

/ Who it's for /

platform engineers and DevOps teams running cloud-native Kubernetes workloads
