CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Dragos Platform Asset Visibility
Mid-market and enterprise industrial operations teams need asset discovery that actually handles legacy protocols and modern IIoT devices in the same scan, which Dragos Platform Asset Visibility does through passive-first collection and deep packet inspection across 600+ OT protocols. The weekly Knowledge Packs ensure your vulnerability priorities don't drift as new CVEs hit industrial stacks, and the Now/Next/Never framework beats generic CVSS scoring for ops that can't patch a PLC on Tuesday. Skip this if you're running mostly IT infrastructure or need point-in-time compliance reporting; Dragos is built for continuous OT monitoring and assumes you'll actually act on what it finds.
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.
