CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Startups and SMBs that need licensed endpoint encryption without infrastructure overhead should evaluate Armour Communications Desktop for its Windows 10 native deployment and trial-first purchasing model. The vendor's NIST CSF 2.0 coverage in Identity Management and Access Control reflects a deliberate focus on authentication enforcement rather than detection or response capabilities. Skip this if you're managing heterogeneous OS environments or expect deep integration with your existing EDR stack; this is a purpose-built communications client, not a platform play.
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.
