Cilium

Cilium is an open-source, cloud-native networking, security, and observability platform designed for Kubernetes and containerized applications. It uses eBPF (extended Berkeley Packet Filter) technology to provide high-performance networking, secure service-to-service communication, and deep visibility into network traffic without relying on traditional iptables-based mechanisms.

Features of Cilium:

• High-performance Kubernetes networking powered by eBPF.
• Advanced security with identity-based and L3–L7 network policies.
• Native support for Kubernetes service discovery and load balancing.
• Deep observability of network flows and application traffic.
• Seamless integration with Kubernetes and cloud-native environments.

To Check the version of cilium, run the following commands:

 $ cilium version

While Cilium delivers powerful networking and security capabilities, correct cluster integration and policy configuration are essential for reliable and secure operation.
