Air Force TFPGA vs ICS-pcap: Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
Air Force TFPGA is a commercial industrial control system security tool by GrammaTech. ICS-pcap 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, 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.
ICS security teams building detection labs or training incident responders should use ICS-pcap as a reference library for actual industrial protocol traffic; the 542 GitHub stars and active contributor model means you're working with real packet captures instead of synthetic data. The tool's value sits entirely in NIST Identify and Detect functions, giving you baseline signatures and anomaly patterns for MODBUS, Profinet, and DNP3, but it won't help you with response automation or recovery orchestration. Skip this if you need a commercial PCAP repository with vendor support or a turnkey IDS; ICS-pcap is a free practitioner resource that only pays off if your team has the bandwidth to ingest and operationalize the captures themselves.
