Armis Centrix™ for Medical Device Security vs Nozomi Networks Nozomi Smart Polling: Side-by-Side Comparison (2026)

Short answer

Mid-market and enterprise healthcare security teams drowning in unmanaged medical device sprawl need Armis Centrix because it actually finds what you don't know is there, then tells you which devices actually matter for patient safety. Passive discovery across unagented devices combined with patient-centric risk prioritization covers NIST ID.AM and DE.CM without requiring network cooperation or device access, which is critical when you're managing legacy ventilators and infusion pumps alongside IT assets. Skip this if your organization wants one platform handling both OT and IT vulnerabilities end-to-end; Centrix prioritizes visibility and continuous monitoring over remediation workflow integration, so you'll still need separate patch management for the devices it surfaces. 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.
