Cybersikkerhed & OT-netværk

From the IT/OT interface to the last sensor

DI-Teknik provides OT cybersecurity solutions for businesses where uptime and operational stability are mission-critical. We help utilities and process industries protect their OT environments against cyber threats — without compromising operational continuity, transparency, or documentation.

Our approach is built on proven OT architecture and network principles, giving you an environment that is easier to manage, more resilient to cyberattacks, and better prepared for compliance requirements such as NIS2.

We have extensive experience across critical industries, including:

Water, wastewater, and utility infrastructure
District heating and the energy sector
Petrochemical industry
Pharma and process industry

End-to-end OT – complete responsibility from start to finish

Many providers stop at advisory services. DI-Teknik delivers the full scope: consulting, design, implementation, operation, and documentation across the entire OT stack — from IT/OT interfaces and monitoring to PLC layers and field devices.

This gives you one integrated delivery with clear interfaces, strong technical transparency, and documentation that supports both daily operations and audit or regulatory requirements.

We design and implement segmented OT networks with security built in from the outset, based on IEC 62443 principles. The objective is to reduce the risk of malware spread, ensure controlled communication between zones, and create a network that is structured, manageable, and well documented.

In practice, this includes segmentation and zoning, DMZ architecture, secure communication paths, limiting lateral movement, and establishing clear boundaries between operations, maintenance, and external vendors.
