CST VerdictBased on our analysis of core features, integrations, company size fit, deployment model, here is our conclusion:
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.
