OT and IT watched side by side, so a stoppage never starts as a breach.
On a production network, downtime and compromise cost the same thing. NetworkFort watches the plant floor and the corporate estate under one model, with collection that cannot interfere with either.
The crossing is where trouble goes.
Attacks that reach production almost always arrive through the corporate side. That path is the thing to watch hardest.
Cell-level baselining
Each production cell profiled on its own traffic rhythm, including shift patterns.
Protocol awareness
Industrial protocols read at protocol level, without probing controllers.
Crossing surveillance
The IT-OT boundary carries the tightest thresholds in the deployment.
Shift rhythm
A second shift that behaves differently from the first is normal, and is learned as such.
Nothing sits in the production path.
Passive collection is not a preference here, it is a requirement, and containment is scoped so that it can never stop a line by accident.
- Mirror-only collectionNo inline device, no failure mode that can halt production.
- Scoped containmentIsolation authority is granted per segment, and production cells can be excluded entirely.
- Maintenance windowsPlanned work is declared in advance, so scheduled changes never page anyone.
One line first.
Proving it on a single line is faster and safer than an estate-wide programme.
Instrument one line
Collection at the cell aggregation layer and the corporate crossing.
Learn the shifts
Two weeks of production rhythm, including changeovers and planned downtime.
Agree authority
Which segments may be isolated automatically, and which never may.
Extend
Repeat per line, reusing the tuning from the first.

Said by someone who runs it.
A representative account of a NetworkFort engagement in this sector.
The thing that sold it internally was that nothing goes inline. Our plant managers had veto and there was nothing for them to veto.
