Armis Threat Detection and Analysis vs Sternum Continuous Monitoring: Side-by-Side Comparison (2026)

Short answer

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 teams monitoring IoT and embedded device fleets should evaluate Sternum Continuous Monitoring for its lightweight SDK and multivariate anomaly detection, which catch memory leaks and firmware anomalies before they reach production. The platform covers DE.CM (continuous monitoring) and ID.AM (asset management) under NIST CSF 2.0, giving you real-time device observability across firmware versions and connectivity states without the overhead of traditional agents. Skip this if your priority is post-incident forensics or integration with broader SOC workflows; Sternum is built for early detection of device-level issues, not incident response.
