CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Security teams building active defense capabilities will find Impost valuable for its honeypot deployment speed and packet inspection depth; the free pricing removes procurement friction for teams piloting deception tactics before committing budget to commercial platforms. The tool's sniffer component catches evasion techniques that passive monitoring misses, particularly useful for validating detection rules before production rollout. Skip Impost if you need managed threat intelligence feeds or automated response workflows; this is a hands-on auditing tool, not a detection platform.
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.
