CST VerdictShort answer
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. Security teams building or testing industrial control system defenses need MiniCPS because it lets you simulate actual PLC behavior and network traffic together, something most cyber ranges bolt on as an afterthought. The framework is free and open source with active development (179 GitHub stars), which matters when you're iterating on ICS-specific attack scenarios that commercial tools won't let you customize. Skip this if your organization needs a polished UI and instructor dashboards; MiniCPS rewards teams comfortable with command-line setup and building their own training workflows around the simulation engine.
