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.
Mid-market and enterprise operations teams struggling to inventory unmanaged devices on their network will find real value in Sepio Cyber's agentless discovery and rogue device detection, which catches shadow assets that traditional asset management tools routinely miss. The platform's strength in NIST ID.AM and PR.PS aligns directly with the hardest part of device hygiene: knowing what's actually connected before you can control it. Skip this if your priority is endpoint response or forensics; Sepio is purely about finding and inventorying what you didn't know you had.
