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.
