CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:

Byos Network Hardening

Mid-market and enterprise teams running sensitive internal networks will want Byos Network Hardening to replace aging jump box architectures; its hardware-enforced microsegmentation eliminates the centralized bottleneck that makes jump boxes attractive targets for lateral movement. The Secure Edge appliance enforces isolation at OSI Layer 1–5, meaning a compromised workload can't phone home or pivot, and the controlled airgaps let you lock down during incidents without severing legitimate access entirely. Skip this if your network is primarily cloud-native and you're already compartmentalizing via VPCs and security groups; Byos is built for hybrid and on-premise environments where you can't rely on native cloud network controls.

Cilium

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.
