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 defending hybrid IT/OT networks need Gatewatcher Plateforme NDR because it actually sees what's moving on your wires without forcing you to choose between network visibility and threat response. The platform covers all six critical NIST Detect and Respond functions, from asset discovery through incident orchestration, and its optical and copper TAP-based capture means you're not relying on agent coverage to find lateral movement. Skip this if your environment is purely cloud-native or if you need a point tool rather than the operational overhead of a full NDR platform; Gatewatcher prioritizes detection depth over ease of deployment.
Security teams investigating application performance issues tied to network behavior will find Justniffer's TCP/IP flow reconstruction more precise than packet sniffers that stop at layer 4, especially for tracking response times across complex request chains. It's free and requires no agents, so you can deploy it immediately on any Linux system without procurement friction. Skip this if you need threat hunting or anomaly detection; Justniffer is a passive analyzer, not a detection engine, and gives you visibility into what happened, not what's attacking you.
