CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise OT teams defending distributed industrial networks will value Endian 4i's ruggedized appliance form factor and native support for legacy protocols without requiring network redesign. The -20°C to +60°C operating range and DIN rail mounting are built for factory floors, not data centers, and the hybrid deployment option lets you start physical and shift virtual as your environment matures. Skip this if your sites run primarily IT-standard infrastructure or if you need NIST Respond capabilities; Endian 4i prioritizes continuous monitoring and resilience architecture over incident recovery workflows.
ICS pentesting teams running Kali-based assessments will find immediate value in Moki Linux because it bundles SCADA-specific tools and payloads that would otherwise require manual curation across multiple repositories. The distribution ships preconfigured for industrial protocols like Modbus and DNP3, cutting setup time for engagements where reconnaissance speed matters. Skip this if you need polished UI/UX or vendor support; at 113 GitHub stars with a volunteer maintainer model, Moki is built for practitioners comfortable reading code and troubleshooting their own environment.
