Based on our analysis of NIST CSF 2.0 coverage, core features, integrations, company size fit, here is our conclusion:
Enterprise and mid-market security teams investigating protocol-level incidents will find Packet Capture (cStor®) invaluable for its lossless capture at 10–200 Gbps paired with petabyte-scale persistent storage, letting you replay and forensically analyze traffic weeks or months after compromise. The onboard indexing and Wireshark integration mean you're not shipping raw PCAPs offsite for analysis; incident response happens at wire speed with full packet fidelity. This is deliberate forensics tooling, not a detection platform; if you need real-time threat hunting or automated anomaly flagging across the network, you'll want this feeding data to a separate NDR layer.
Mid-market and enterprise SOCs with hybrid infrastructure need Stamus Clear NDR for the network visibility that endpoint tools can't touch, particularly east-west traffic that most teams still miss entirely. The tool captures full packet data and extracts files at line rate while feeding SIEM and Suricata integrations, covering the critical gap between detection and forensic-grade incident analysis that NIST RS.AN demands. Skip this if your team lacks the personnel to tune DPI signatures or interpret network protocol anomalies; Stamus is built for organizations that can staff network detection, not those looking to automate their way out of analyst shortage.
