Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Nozomi Networks Nozomi Smart Polling
Mid-market and enterprise operations teams managing OT/IoT environments where passive discovery leaves blind spots will get the most from Nozomi Networks Nozomi Smart Polling; active polling finds non-communicating devices and firmware patch status that network traffic alone cannot surface. The tool integrates directly with Guardian's passive baseline, meaning you're adding surgical interrogation to existing visibility rather than bolting on another silo. Skip this if your OT footprint is small enough that passive discovery already covers your critical assets, or if you lack the network segmentation to safely execute active polling without production risk.
Armis Centrix™ Medical Device Security
Mid-market and enterprise healthcare security teams need medical device visibility that doesn't break clinical workflows, and Armis Centrix™ delivers this through agentless discovery and a Clinical Impact Score that prioritizes threats by patient safety risk rather than generic severity. The platform covers the full ID.AM to DE.AE arc (asset discovery through anomaly analysis) and handles the legacy device inventory that most hospitals refuse to upgrade, which is where 80 percent of the actual risk lives. Skip this if your organization runs primarily modern, patchable infrastructure; Centrix is purpose-built for the messy reality of connected anesthesia machines and decades-old imaging systems, not general IT asset management.
