Segmented plant control networks and built OT visibility without touching a single control loop.
Overview
In an operating plant, the safest change is often no change — so everything was passive first. We mapped every asset from mirrored traffic, established a normal baseline over six weeks, then introduced segmentation and a one-way data path to the corporate side during a planned turnaround. Engineers gained visibility they had never had, and not one control loop was interrupted.
