s7scan is a free operational technology asset discovery tool. Viakoo CPS Protection Platform is a commercial operational technology asset discovery tool by viakoo. Compare features, ratings, integrations, and community reviews side by side to find the best operational technology asset discovery fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, 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.
Viakoo CPS Protection Platform
Enterprise and mid-market ops teams managing OT/ICS environments where agentless discovery is non-negotiable will get real value from Viakoo CPS Protection Platform; its firmware and certificate lifecycle automation cuts the manual work that typically leaves vulnerabilities unpatched for months. The platform's support for tightly coupled devices and OPC-UA certificate provisioning means it actually works with legacy industrial gear rather than forcing workarounds. Skip this if your primary concern is detecting active threats in motion; Viakoo is built around asset hygiene and compliance posture, not behavioral anomaly detection.
