CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Startups and small teams needing a lightweight IPsec VPN client without infrastructure overhead should pick NCP Secure Entry Client; it handles up to 100 users across Windows and macOS with one-click tunnel initiation and automatic firewall policy selection based on network context, cutting deployment friction that larger VPN platforms create. The tool covers NIST PR.AA (identity and access control) and PR.IR (infrastructure resilience), meaning authentication workflows and failover behavior are architecturally sound. Skip this if you need cloud-native connectivity, advanced threat detection, or support for more than 100 concurrent remote workers; NCP is purpose-built for distributed teams using traditional on-premises gateways, not hybrid or zero-trust environments.
Teams building zero-trust networks across distributed infrastructure will find Nebula's peer-to-peer architecture eliminates the centralized controller bottleneck that plagues traditional VPN solutions. With 17,138 GitHub stars and active deployment in production networks, the tool proves its stability without requiring proprietary hardware or licensing overhead. Skip Nebula if your organization needs built-in endpoint compliance enforcement or relies on legacy RADIUS authentication; it's a networking primitive, not an identity layer.
