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

Armis Centrix™ for Medical Device Security

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.

GRASSMARLIN

Operations teams defending critical infrastructure without dedicated ICS/SCADA visibility should start with GRASSMARLIN; its passive network mapping gives you topology sight-lines without touching production systems, which matters when downtime costs six figures per hour. The tool is free and runs on commodity hardware, so deployment friction is nearly zero for teams of any size. The tradeoff is real: GRASSMARLIN maps what exists but doesn't actively hunt for misconfigurations or lateral movement, so it's a foundation layer, not a standalone defense.
