Cilium
Definition
Cilium is an open-source networking, observability, and security project for Kubernetes that uses eBPF to enforce network policies at the kernel level with high performance. It supports Layer 7 (HTTP, gRPC, Kafka) policy enforcement, transparent encryption via WireGuard or IPsec, and detailed network flow visibility through Hubble.
Cilium is increasingly adopted as the CNI of choice for security-sensitive Kubernetes deployments.
