CST Verdict

Based on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:

Acalvio ShadowPlex

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.
