CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise carriers need 6WIND Virtual Service Router (VSR) if your routing infrastructure must run across bare metal, VMs, and containers without ripping out legacy systems. The tool handles IPsec VPN, CGNAT, and L3/L4 filtering in a single software stack that deploys on x86 and ARM, which matters when your network spans incompatible hardware generations. Skip this if you're a cloud-native shop expecting container-first tooling; VSR is built for operators managing hybrid physical-virtual networks, not startups standardizing on Kubernetes alone.
Startup and SMB security teams building multi-cloud infrastructure will get the most from NetBird Connect because peer-to-peer WireGuard encryption eliminates the need for expensive hub-and-spoke VPN appliances and centralizes access control without centralized gatekeeping. The self-hosted deployment option and native SSO integration mean you control your own key distribution and can tie network access directly to your identity provider, hitting both PR.AA and PR.IR on NIST CSF 2.0. Skip this if you need granular application-layer visibility or encrypted traffic inspection; NetBird operates at the network layer and won't give you payload inspection that traditional firewalls provide.
