ICS-pcap vs Radiflow iCEN: Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
ICS-pcap is a free industrial control system security tool. Radiflow iCEN is a commercial industrial control system security tool by Radiflow. Compare features, ratings, integrations, and community reviews side by side to find the best industrial control system security fit for your security stack.
CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
ICS security teams building detection labs or training incident responders should use ICS-pcap as a reference library for actual industrial protocol traffic; the 542 GitHub stars and active contributor model means you're working with real packet captures instead of synthetic data. The tool's value sits entirely in NIST Identify and Detect functions, giving you baseline signatures and anomaly patterns for MODBUS, Profinet, and DNP3, but it won't help you with response automation or recovery orchestration. Skip this if you need a commercial PCAP repository with vendor support or a turnkey IDS; ICS-pcap is a free practitioner resource that only pays off if your team has the bandwidth to ingest and operationalize the captures themselves.
Mid-market and enterprise OT teams managing multiple industrial sites will get the most from Radiflow iCEN because it consolidates asset monitoring and threat intelligence across dispersed locations without requiring agents on legacy control systems. The platform covers continuous monitoring and risk visualization across NIST DE.CM and GV.RM, and its one-way communication model works where bidirectional traffic isn't feasible in air-gapped environments. Skip this if you need SOAR automation or incident response workflows; iCEN is built for visibility and risk prioritization, not playbook execution.
