CST VerdictBased on our analysis of core features, integrations, company size fit, deployment model, here is our conclusion:
Enterprise and mid-market teams deploying multi-cluster Kubernetes across hybrid infrastructure should pick Isovalent Cilium Mesh for identity-based microsegmentation that actually works at the kernel level instead of relying on overlay abstractions. Its eBPF runtime enforcement covers PR.AA and DE.CM functions simultaneously, meaning you get access control and continuous monitoring from the same data plane without separate agents. Skip this if your infrastructure is mostly VMs or you need CNAPP features like vulnerability scanning; Cilium is a networking and security layer, not a workload protection platform.
