OT Cybersecurity and Controlled Access in a Production Network
A flat industrial network was transformed through asset visibility, segmentation and recorded remote access.
Company names, facility locations and identifying information have been removed. Performance values are presented as rounded ranges to protect customer confidentiality.
OT Cybersecurity and Controlled Access in a Production Network
PLC, HMI, engineering stations and third-party access shared broad trust boundaries with limited asset and change visibility.
The objective was to create a sustainable operating model rather than automate an isolated task.
Operational consistency
PLC, HMI, engineering stations and third-party access shared broad trust boundaries with limited asset and change visibility.
Integrated architecture
We established asset inventory, zones and conduits, least-privilege firewall rules, secure remote access and event monitoring.
Scenario-based acceptance
Normal operation, exceptions, recovery and critical safety scenarios were tested with operations teams.
Engineering approach
From requirement to system behavior
- Field requirements and operating constraints were modelled before implementation.
- Equipment, software and data interfaces were designed around a common operating context.
- Operator guidance, alarms and recovery scenarios were included in the design.
Controlled implementation
- We established asset inventory, zones and conduits, least-privilege firewall rules, secure remote access and event monitoring.
- Changes were verified through traceable test and acceptance scenarios.
- Operations and maintenance teams participated in commissioning and handover.
Measurable operational outcome
The OT environment became visible, segmented and defensible without compromising production continuity.
