Short on time? Here's the quick answer
We've tested both tools. Here's who should pick what:
Cilium
Cloud native networking, observability, and security powered by eBPF.
Best for you if:
- • You want high performance due to eBPF kernel-level operation
- • You want granular security policies based on workload identity
Kuma
Modern control plane for microservices and service mesh across Kubernetes and VMs.
Best for you if:
- • You want a fully free tool (Cilium requires payment)
- • You want supports both Kubernetes and Virtual Machines, offering flexibility for hybrid environments
- • You want easy to use with out-of-the-box policies for security, observability, and traffic management
