Armis Threat Detection and Analysis vs Nozomi Networks Nozomi Smart Polling: 2026 Comparison

Armis Threat Detection and Analysis

Manufacturing and utilities teams flying blind on OT/IoT asset inventory should start with Armis Threat Detection and Analysis because passive discovery actually works without disrupting operational networks, a hard requirement that active-only scanners violate. The platform maps assets to CVEs and control gaps across NIST ID.AM and ID.RA simultaneously, giving you a risk-ranked inventory instead of a spreadsheet; deployment is cloud-native, so you're not managing another appliance. Skip this if your OT environment is heavily air-gapped or you need deep forensics and response automation; Armis excels at visibility and threat detection, not incident playbooks.

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.
