OT network visibility

Most industrial sites do not know their production network completely: which devices talk, over which protocols, and what reaches the outside. For IEC 62443 and NIS2 that knowledge is the starting point for everything else.

We listen passively — no active scans, no interference with production. You get a full asset and communication inventory, the unexpected connections, the IT/OT boundary crossings, and an assessment against the zone and conduit model. Where you want detection afterwards, we write a rule set derived from what we actually found — not a standard set that produces a hundred false positives a day.
