DNSSense Roaming Clients (DNSDome)
SMB and mid-market security teams managing distributed workforces will get the most from DNSSense Roaming Clients because DNS interception sidesteps the deployment friction of traditional endpoint agents while making protection tamper-proof at the network layer. The agent works across Windows, macOS, and Linux without requiring centralized network enforcement, and its NIST PR.AA coverage confirms it actually restricts access rather than just logging who tried. Skip this if you need behavioral EDR or binary analysis; DNSSense is a perimeter tool that stops bad DNS queries, not suspicious processes.
Mid-market and enterprise security teams managing mixed infrastructure (on-prem, cloud, OT) need Portnox Cloud because it enforces least-privilege access at command level rather than just network segment level, catching lateral movement that traditional NAC misses. Cloud-native deployment with zero maintenance overhead and vendor-agnostic controls across NAC, ZTNA, and RADIUS means you're not locked into a single vendor's infrastructure stack. Skip this if your primary concern is endpoint detection and response; Portnox prioritizes access enforcement over post-breach forensics, and lacks the detection depth needed for organizations treating endpoint compromise as their threat model.
