Why Production Networks Get Breached
Manufacturing cybersecurity fails in predictable ways. These are the three weaknesses we find on almost every plant floor.
Corporate and production sit on the same broadcast domain, so ransomware in the front office reaches the line.
Machine builders and integrators hold permanent VPN or cellular access that nobody audits.
Most plants cannot produce a current list of what is on the production network.
Controller-Safe by Design
OT cybersecurity only works if it cannot hurt production. Our monitoring model is built around that constraint and aligned with IEC 62443 and the NIST CSF Manufacturing Profile.
Passive Monitoring Only
We deploy a network sensor at the IT/OT boundary (Purdue model Level 3 / DMZ). No agents on controllers, no active scanning of production assets, no traffic injected onto the plant network.
We Do Not Touch a Running Line
Response actions on OT assets are recommended by our analysts and executed by your team under runbooks agreed in advance.
Framework-Aligned
Assessments, detections, and reporting map to IEC 62443 and the NIST CSF Manufacturing Profile, so progress is measurable against recognized standards.
OT Service Tiers
Managed OT security for Wisconsin manufacturers — priced per site, not per endpoint.
