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

Armis Centrix™ Medical Device Security

Mid-market and enterprise healthcare security teams need medical device visibility that doesn't break clinical workflows, and Armis Centrix™ delivers this through agentless discovery and a Clinical Impact Score that prioritizes threats by patient safety risk rather than generic severity. The platform covers the full ID.AM to DE.AE arc (asset discovery through anomaly analysis) and handles the legacy device inventory that most hospitals refuse to upgrade, which is where 80 percent of the actual risk lives. Skip this if your organization runs primarily modern, patchable infrastructure; Centrix is purpose-built for the messy reality of connected anesthesia machines and decades-old imaging systems, not general IT asset management.

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.
