Armis Centrix™ for Medical Device Security vs Athena Dynamics RAD: Side-by-Side Comparison (2026)

Short answer

Mid-market and enterprise healthcare security teams drowning in unmanaged medical device sprawl need Armis Centrix because it actually finds what you don't know is there, then tells you which devices actually matter for patient safety. Passive discovery across unagented devices combined with patient-centric risk prioritization covers NIST ID.AM and DE.CM without requiring network cooperation or device access, which is critical when you're managing legacy ventilators and infusion pumps alongside IT assets. Skip this if your organization wants one platform handling both OT and IT vulnerabilities end-to-end; Centrix prioritizes visibility and continuous monitoring over remediation workflow integration, so you'll still need separate patch management for the devices it surfaces. 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.
