Cilium

Cilium, developed by Isovalent, is an open-source solution that aims to provide secure and observable network connectivity for container and cloud-native workloads. According to the vendor, Cilium leverages the kernel technology eBPF to deliver advanced networking capabilities, including load balancing, traffic management, and bandwidth optimization. It also enables secure connectivity through zero-trust network segmentation and identity-based enforcement. Additionally, Cilium offers insights into network flows, metrics, and visualizations for troubleshooting and monitoring purposes.
