Passive Module

Runs on VIGIA-IOTBOX, watching the customer’s IT network for OT devices bridging across — like a cell’s Main PLC reporting to a MES server — without ever probing inside an isolated cell. A boundary-hygiene signal, not a way to complete a cell’s inventory.

It never sits inside an isolated OT cell itself, so it’s not a substitute for the active scanning Solo Analytics or Site Analytics already does there — it’s a second, independent signal watching the one place a cell’s isolation is most likely to quietly fail: the boundary with IT.
