Features, pricing, ratings, and pros and cons, compared head to head.
Armis Threat Detection and Analysis is a commercial ot asset discovery tool by Armis. ServiceNow Security Operations is a commercial security orchestration automation and response tool by ServiceNow. Compare features, ratings, integrations, and community reviews side by side to find the best ot asset discovery fit for your security stack. Independent and vendor-neutral: our scores and rankings are earned, never bought — sponsored placement is always labeled.
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. Mid-market and enterprise security teams drowning in disconnected alerts will find real value in ServiceNow Security Operations because its incident response automation actually reduces noise by routing tickets through role-based workflows tied to your existing ticketing infrastructure. The platform covers NIST's full RS (Respond) and most of DE (Detect) functions with native integrations to Splunk, CrowdStrike, and Tenable, meaning fewer context switches between tools. Skip this if your priority is vulnerability management sophistication; the risk-based prioritization is solid but won't compete with dedicated platforms like Tenable or Qualys for technical depth in that specific function.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
