Armis Threat Detection and Analysis vs Athena Dynamics RAD: Side-by-Side Comparison (2026)

Armis Threat Detection and Analysis

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.

Athena Dynamics RAD

Mid-market and enterprise maritime operators need RAD because it discovers OT assets across hybrid IT/OT networks without requiring onboard hardware or disrupting vessel systems, a constraint that kills most traditional discovery tools in this domain. The ClassNK certification and passive scanning with 60-minute active phases prove the vendor understands maritime ops; E26 compliance support closes a real gap in the category. Skip this if your fleet runs purely air-gapped networks or if you need NIST ID.RC recovery capabilities built in; RAD prioritizes asset visibility and continuous monitoring over incident response orchestration.
