Acalvio ShadowPlex vs ICS-pcap: Side-by-Side Comparison (2026)
Features, pricing, ratings, and pros & cons — compared head-to-head.
Acalvio ShadowPlex is a commercial honeypots & deception tool by Acalvio Technologies. ICS-pcap is a free industrial control system security tool. Compare features, ratings, integrations, and community reviews side by side to find the best honeypots & deception 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 security teams with exposed APIs, web applications, or IoT infrastructure should use ShadowPlex to catch reconnaissance and credential attacks before they reach production systems. The platform's external-facing decoys generate high-fidelity threat intelligence in STIX format while monitoring for password spraying and brute-force attempts, directly addressing ID.RA and DE.CM in NIST CSF 2.0. Skip this if your attack surface is entirely internal or if you need deep visibility into post-breach lateral movement; ShadowPlex is optimized for early detection at the perimeter, not incident response.
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.
