Cilium reviews and summary

Cilium is an open-source, cloud-native networking, security, and observability platform built on the revolutionary eBPF (extended Berkeley Packet Filter) technology inside the Linux kernel. Unlike traditional networking that operates at the IP and port level, Cilium understands and can enforce security and networking policies based on application-layer concepts like HTTP paths, service identities, and API calls. This provides granular, identity-aware security for containerized workloads and microservices, enabling a true zero-trust network model. Additionally, eBPF allows Cilium to offer deep observability into application behavior and network flows with minimal performan...
