CST VerdictShort answer
Mid-market and enterprise operators managing SCADA, DCS, or PLC environments should choose Citicus ICS if your team lacks a structured, ICS-native approach to risk quantification and remediation tracking. The platform's five-factor risk scorecard and PDCA lifecycle directly address NIST CSF 2.0 Risk Assessment and Risk Management Strategy, with configurable controls mapped to CPNI and NIST 800-82, which matters when regulators audit your control baselines. Skip this if you're a small site with minimal ICS complexity or need real-time threat detection alongside your risk scoring; Citicus is governance and planning, not operational alerting. 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.
