CST VerdictShort answer
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. SMB and mid-market teams managing fragmented network access controls will find Knocknoc's identity-first allowlisting approach faster to deploy than rip-and-replace zero trust platforms. It orchestrates your existing firewall and network gear through SSO authentication rather than forcing new infrastructure, which cuts implementation friction when you're resource-constrained. The hybrid deployment model and scripting backend let you protect both internal subnets and OT networks without separate tools. Skip this if you need endpoint detection or behavioral analytics layered on top; Knocknoc is network perimeter hardening, not a full access control suite.
