Best OT and ICS Security Monitoring Software in 2026
Industrial environments have distinct monitoring needs, and OT and ICS security software can be compared by the assets and activity it helps track. Check OT asset discovery and passive monitoring alongside supported protocols and SIEM integration. Deployment and asset limits offer further operational points to consider; free-plan availability and paid-from pricing help frame cost. Nozomi Networks Platform, Honeywell Forge, and Kaspersky Industrial CyberSecurity Platform are among the entries, as are Radiflow iSID and Claroty CTD. Use the listed dimensions to compare visibility and integration needs against the environment you need to monitor.
