On a plant floor, a security incident is measured in stopped lines rather than lost records. We secure converged IT and OT estates without putting production availability second to policy.
Identify any engineering workstation reaching the control network from outside its maintenance window.
Flagged: 1 vendor laptop bridging the cell network at 02:40 with no change ticket. Port disabled, line unaffected, maintenance lead paged.
Controls designed around uptime: nothing we deploy on the plant floor is allowed to become the reason a line stops.
Most plants converged IT and OT gradually and never redrew the boundary. We segment a live estate in stages, working around planned downtime rather than demanding it.
Controllers commissioned twenty years ago cannot be patched, cannot be scanned, and often cannot even be interrogated safely.
Office IT and control systems ended up on the same fabric one project at a time, so ransomware reaches the line from an email.
We map the OT estate by listening rather than probing, so nothing on the line is disturbed while we build the picture.
Segmentation follows the IEC 62443 model and lands in scheduled increments, each reversible and each proven before the next.
Your exposure includes every integrator with a VPN, every OEM with remote diagnostics and every supplier connected to your planning systems.
Machine builders keep standing tunnels into their equipment for diagnostics, usually outside your identity and logging estate.
Tier-two suppliers with weak security hold live access to your planning and quality systems, and to your product designs.
OEM access runs through a broker with recording, time boxing and approval, replacing always-on tunnels nobody reviews.
Suppliers are risk-tiered by the access they hold, with proportionate control requirements and evidence collected on a cycle.
How we secure a converged plant estate in increments, each one scheduled around production rather than against it.
Map every controller, HMI and engineering station without touching the line.
Draw IEC 62443 zones and conduits against how the plant actually operates.
Land segmentation in reversible increments inside planned maintenance windows.
Monitor OT traffic for anomalies and report posture to plant and group leadership.
No. We start passively — listening to a network tap or span port and building the asset inventory from the traffic itself. Nothing is probed, scanned or queried on the control network until you have seen the map and agreed which devices can safely be interrogated actively.
Yes, and it is the normal case. Segmentation is delivered in reversible increments that land inside your existing maintenance windows. Each stage is proven before the next is scheduled, so the rollout follows your production calendar rather than asking you to clear one.
Our OT engineers will map your plant estate, show you where the IT and OT boundary has quietly disappeared, and outline a 90-day plan.
