AhnLab CPS PLUS vs ICSFuzz: 2026 Comparison
AhnLab CPS PLUS is a commercial industrial control system security tool by AhnLab. ICSFuzz is a free industrial control system security tool. Compare features, ratings, integrations, and community reviews side by side to find the best industrial control system security fit for your security stack.
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.
ICS engineers and red teamers validating PLC firmware will find value in ICSFuzz for its direct approach to fuzzing control logic without requiring external hardware or complex lab setup. The tool is free and openly available on GitHub, lowering the barrier for teams already spending budget on commercial ICS scanners to add native fuzzing capability. The low star count signals limited adoption and community validation; this is best suited for practitioners comfortable troubleshooting edge cases and integrating a single-purpose tool into existing workflows, not teams expecting vendor support or turnkey vulnerability management.
