Differences between Operational Technology and Information Technology

Not all networks are alike

Secure communication, resulting in a secure exchange of data between Operational Technology (OT) and Information Technology (IT), is the backbone of digitalization. Industrial networks and office networks both use Ethernet-based communication, but they differ in several ways. Both networks have highly specific requirements. They have to be taken into account when planning the OT/IT connection in order to ensure a reliable data exchange in enterprise networks.

How can a smooth collaboration of OT and IT be achieved?

At SPS fair 2022, our expert Daniel Mai talked about OT and IT. Watch the video and learn how OT/IT collaboration and cybersecurity interact. In addition, you will discover examples from different industries, such as water/wastewater treatment.

Optimally connect OT and IT networks

How can smooth collaboration between OT and IT be achieved? It’s important to understand the requirements of both networks. Solution providers with experience in both areas understand industrial networks as a part of automation. They apply different requirements to planning greenfield and brownfield projects than they do to panning office and data center networks. They also know the requirements of IT and include them in their calculations.

Two worlds come together in the enterprise network

Requirements for IT mainly focus on the user experience, meaning ease of operation based on standards, as well as data transmission performance, such as the transmission of audio and video via a shared infrastructure. It’s all based on comprehensive cybersecurity that prioritizes privacy.


On the other hand, OT mainly focuses on the safe operation of plants with reliable data transmission for time-critical applications, including in harsh environments. In this case, special attention is paid to long-term availability and, of course, compliance with security standards.


Siemens understands both sides. As a leading provider of automation technology, we know exactly how industrial networks have to be designed. Our IT experience helps us with the digitalization of plants and merging of the virtual and physical worlds. We also rely on strong partners for support.
