Network and infrastructure telemetry is the richest source most teams hold and the one they act on least. Flow logs, DNS, VPC traffic and cloud network findings get retained for audit while the detection value sits unused, so a finding becomes a ticket rather than an outcome. That gap matters more now, because AI-driven detection and investigation are only as good as the network-layer evidence underneath them.

This discussion covers how teams are connecting that signal to investigation and response across multi-account, multi-region AWS environments: which detections hold up at volume, where AI and automation carry real weight and where they produce noise, and what an authorization boundary or a FedRAMP obligation changes about the design. Detection engineers bring what works, security leaders bring what the compliance timeline demands, and both constraints are real.
