Features, pricing, ratings, and pros & cons — compared head-to-head.
s7scan is a free ot asset discovery tool. SAM Intelligence is a commercial ot asset discovery tool by SAM Seamless Network. Compare features, ratings, integrations, and community reviews side by side to find the best ot asset discovery fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
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.
Enterprise ISPs and network operators managing sprawling device ecosystems need SAM Intelligence for the one thing that matters most: actually knowing what's connected to your network before it becomes a liability. The platform's 250M+ fingerprinted device database and ability to auto-discover and classify 18,000+ device types across CPE and mobile deployments gives you asset visibility that manual audits will never catch, and its continuous monitoring function directly addresses NIST ID.AM and DE.CM requirements. Skip this if you're a smaller regional provider without the operational overhead to act on granular device intelligence; the value compounds only at scale.
