ICSREF is a free industrial control system security tool. Nozomi Networks Nozomi Networks Platform is a commercial industrial control system security tool by Nozomi Networks. Compare features, ratings, integrations, and community reviews side by side to find the best industrial control system security fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, 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.
Nozomi Networks Nozomi Networks Platform
Mid-market and enterprise teams defending industrial control systems and OT networks need Nozomi Networks Platform because it actually maps heterogeneous ICS/SCADA environments instead of forcing them into IT-centric asset models. The platform's dual strength in asset discovery and real-time anomaly detection addresses NIST ID.AM and DE.AE simultaneously, which matters when your production line is the business. Skip this if your environment is purely IT-based or if you need tight SOAR integration; Nozomi is built for OT-first shops where network visibility and process behavior matter more than ticketing workflow.
ICSREF is a modular framework that automates reverse engineering of CODESYS industrial control system binaries to identify functions, library calls, and program structures.
