Portlurker is a free honeypots & deception tool. Acalvio ShadowPlex is a commercial honeypots & deception tool by Acalvio Technologies. 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:
Security teams running constrained infrastructure or lab environments who need a lightweight honeypot for early warning of reconnaissance will appreciate Portlurker's minimal footprint and protocol-agnostic listening. Written in Rust, it consumes virtually no CPU or memory overhead while still capturing connection attempts and guessing service types; the SQLite logging keeps data local and queryable without external dependencies. Skip this if you need centralized alerting, correlation with other sensors, or anything beyond passive observation of what's touching your ports.
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.
