Armis Threat Detection and Analysis is a commercial operational technology asset discovery tool by Armis. SAM rAPId is a commercial operational technology asset discovery tool by SAM Seamless Network. Compare features, ratings, integrations, and community reviews side by side to find the best operational technology asset discovery fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
Startups and mid-market ops teams struggling to inventory IoT and OT devices will find SAM rAPId's fingerprinting database of 500M+ devices far more useful than generic asset scanners that return incomplete or misclassified results. The API-first model means you integrate it directly into your existing workflows instead of running another scanning tool, and batch identification lets you process thousands of devices without manual effort. Skip this if your network is purely IT infrastructure with standard servers and workstations; you'll get better value from cheaper CMDB tools that don't need the fingerprinting layer SAM rAPId is built around.
