Case Study: ilionx achieves secure, self-service Kubernetes networking with Cilium

Securing the Networking Stack with Cilium

ilionx, an IT consultancy firm, faced significant challenges with the networking and security of its self-service Kubernetes platform. Their initial setup, using a different CNI plugin and a manual private firewall appliance, created roadblocks to automation, increased complexity, and lacked the robust, automatable network policies required for their multi-tenant clusters. This prompted their search for a new solution, leading them to the Cloud Native Computing Foundation's Cilium.

By implementing Cilium from the Cloud Native Computing Foundation, ilionx replaced their entire networking stack. Cilium provided automatable L3 firewalling and granular network policies, which secured multi-tenant environments and provided deep observability into network traffic. The solution drastically simplified administration, enabled true developer self-service, and eliminated manual configuration hassles. Measurable impacts include securing over 500,000 data points and 40,000 connections daily for their 35+ customers, all while achieving a more secure and automated platform.
