CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Aireye WDR (Wireless Detection and Response)
Mid-market and enterprise security teams struggling with rogue devices and lateral movement across Wi-Fi networks should evaluate Aireye WDR for its agentless asset discovery and real-time connection termination, which catches threats that traditional network monitoring misses. The platform's device-to-device interaction visibility and automated policy enforcement address the specific NIST PR.AA and DE.CM gaps most organizations have in wireless access control. Skip this if your wireless footprint is minimal or your IT and OT teams refuse to cede Wi-Fi blocking decisions to automated systems; the enforcement model assumes you want the tool making split-second connection decisions without human approval.
Security teams running flat networks or investigating lateral movement will find Mercury's value in its lightweight metadata capture; the tool costs nothing and requires no agents, making it deployable in minutes across segmented environments where traditional NDR gets blocked by complexity. Its 501 GitHub stars reflect sustained adoption among practitioners who need quick packet context without the overhead of full-packet capture or ML-heavy anomaly scoring. Skip Mercury if your organization needs behavioral baselining or automated response workflows; it's fundamentally a data collection and analysis instrument, not a detection engine.
