ICSREF vs Radiflow iCEN: 2026 Comparison
ICSREF 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:
OT security teams responsible for CODESYS-based manufacturing environments should pick ICSREF if reverse engineering is your bottleneck; the tool automates what takes analysts weeks manually, and the 179 GitHub stars indicate active use in real deployments. The modular framework design means you're not paying licensing costs to test it against your own binaries first. This isn't useful if your sites run Siemens TIA Portal or Allen-Bradley systems; ICSREF's value is CODESYS-specific, so confirm your install base before allocating analyst time to learn it.
