CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Platform teams running Kubernetes on-premises or in hybrid clouds will get the most from Cilium because its eBPF kernel-level enforcement eliminates the latency and blind spots of traditional overlay networking. With 23,959 GitHub stars and active deployments at scale across financial services and public sector organizations, Cilium's approach to policy enforcement at the dataplane level is proven; it also handles observability without requiring sidecar injection, which keeps resource overhead predictable. Not the right fit for teams needing a managed SaaS experience or those prioritizing CSPM and infrastructure compliance scanning over network microsegmentation.
