CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
cPacket Network Observability Platform
Enterprise and mid-market security teams operating hybrid networks will extract the most value from cPacket Network Observability Platform because it captures and analyzes every packet at line rate without sampling, giving you forensic-grade visibility into lateral movement and data exfiltration that sampled tools miss. Lossless packet capture at 200Gbps and microburst detection directly support NIST DE.CM and DE.AE functions, catching anomalies that flow-based monitoring overlooks. Skip this if your network is purely cloud-native or you lack the expertise to operationalize packet intelligence; cPacket demands analysts who know how to hunt in raw packet data, not just read dashboards.
Security teams running Zeek for network visibility will find immediate value in RDFP for identifying unauthorized or outdated Remote Desktop clients on the wire, something most NDR platforms treat as noise rather than a detection signal. The script requires no additional infrastructure beyond existing Zeek deployments and costs nothing, making it a quick add to detect client-side RDP vulnerabilities that endpoint tools often miss. Skip this if your organization relies on application allowlisting or has already eliminated RDP from your environment; RDFP is tactical network hygiene, not a replacement for access controls.
