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

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. IT teams managing heterogeneous fleets of 500+ macOS and Linux endpoints will get the most from Fleet because it actually scales without per-seat licensing costs. The open-source model and 6,144 GitHub stars signal a real community maintaining this, not abandonware; you can read the code and fork it if the maintainers ghost you. Skip this if you need Windows-first management or mobile device support, or if your security org demands a single vendor handling both endpoint detection and vulnerability scanning under one contract.
