Air Force TFPGA is a commercial industrial control system security tool by GrammaTech. Cylus CylusOne is a commercial industrial control system security tool by Cylus. Compare features, ratings, integrations, and community reviews side by side to find the best industrial control system security fit for your security stack.
Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Mid-market and enterprise manufacturers with mission-critical industrial control systems need Air Force TFPGA to detect hardware Trojans and counterfeits at the component level, where supply chain compromise actually enters your infrastructure. The tool requires no golden reference model, meaning you can assess legacy FPGA inventory immediately without waiting for baseline data, and its self-characterization testing directly supports NIST GV.SC supply chain risk management. Skip this if your threat model doesn't include hardware-level adversaries or if you're sourcing components exclusively from tier-one vendors with ironclad provenance; the ROI shrinks fast for organizations with lower supply chain risk exposure.
Rail operators at mid-market and enterprise scale should buy Cylus CylusOne if your network runs a mix of legacy and modern protocols and you need passive visibility without disrupting operations. The platform's passive asset discovery and DPI-based threat detection across railway-specific protocols, combined with IEC 62443-3-2 compliance support, directly addresses the visibility gap most rail teams face. Skip this if your primary concern is incident response automation or recovery orchestration; CylusOne excels at the ID and DE functions but offers limited RS capabilities, meaning you'll still need separate playbook execution tools downstream.
