Open Source Ecosystem

The future of networking is open source

We maintain


Cilium is eBPF-powered networking, observability, and security for a cloud native world.


eBPF enables safe, efficient extensibility for Linux kernel networking, security, and tracing.

We contribute


Kubernetes is the de facto standard for running cloud native apps. Cilium integrates via the Container Network Interface (CNI).


Envoy is a proxy with rich support for L7-protocols like HTTP. Cilium accelerates Envoy for efficient API-layer processing.
