AhnLab CPS PLUS vs HVAC Traces: Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
AhnLab CPS PLUS is a commercial industrial control system security tool by AhnLab. HVAC Traces 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 security teams building or tuning network detection for critical infrastructure will find value in HVAC Traces because it offers actual packet captures from real HVAC environments rather than synthetic data. The repository includes five full pcap files that let you test your IDS signatures against genuine control system traffic, catching false positives before deployment. Skip this if you need a managed service or vendor-backed threat intelligence; this is a free GitHub project maintained by practitioners, not a commercial product, so you're responsible for integrating and updating the data yourself.
