Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
Manufacturing and critical infrastructure security teams operating Siemens environments need s7scan because it's the only free tool that enumerates PLCs at scale without requiring credentials or vendor partnerships. The 150 GitHub stars reflect active adoption by OT practitioners who've validated it against real Siemens deployments. Skip this if you're looking for a commercial support contract or cross-vendor asset discovery; s7scan is laser-focused on Siemens reconnaissance and won't help you map your Rockwell or Schneider infrastructure.
