CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Mid-market and enterprise operations teams protecting manufacturing or critical infrastructure will find AhnLab CPS PLUS valuable for its unidirectional data diode capability and portable endpoint scanning, which work in air-gapped or severely restricted OT networks where standard agents fail. The platform covers 10 of 23 NIST CSF 2.0 functions with particular strength in asset identification, continuous monitoring, and incident analysis across IT and OT together. Skip this if your priority is recovery and resilience post-breach; AhnLab emphasizes prevention and detection over response coordination, and the Asia-Pacific vendor presence means longer support latencies for North American teams.
Mid-market and enterprise operators managing water, energy, or manufacturing OT environments will get the most from Rubyk OT because it prioritizes continuous asset monitoring and anomaly detection rather than assuming your air-gapped networks stay air-gapped. The tool's strength in DE.CM and DE.AE means you'll catch unusual OT behavior before it cascades into downtime, which matters when your infrastructure can't afford the detection lag that generic network monitoring introduces. Skip this if your organization needs post-incident forensics and recovery orchestration; Rubyk OT is built for prevention and early warning, not remediation automation.
