Phosphorus xIoT Global Device Network vs s7scan: Side-by-Side Comparison (2026)

Phosphorus xIoT Global Device Network

Mid-market and enterprise security teams struggling to inventory non-traditional IT assets will benefit most from Phosphorus xIoT Global Device Network, which catalogs over 1 million device profiles across IoT, OT, and medical device categories using active discovery that doesn't require network taps or traffic inspection. The 950-plus vendor support and patented Genus-Species classification method mean you'll identify cameras, printers, access control systems, and industrial controllers that passive scanning typically misses, directly addressing the ID.AM gap most organizations face. Skip this if your environment is primarily traditional IT infrastructure; the value proposition assumes significant non-IT device sprawl that justifies the commercial pricing model.

s7scan

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.
