IT/OT integration

Digitalisation means that IT and OT systems are connected. This integration presents security challenges and requires special solutions.

Operational Technology (OT) refers to all the subsystems needed to manage and monitor a physical process, for example at a power station or a factory. OT usually consists of programmable logic controllers (PLCs) and supervisory control and data acquisition (SCADA) systems. IT refers to the business and office systems that most organisations use.

Historically, OT systems were often entirely standalone. However, the need to connect OT to other systems has grown with the digitalisation of society. IT and OT are therefore connected, and similar technology is often used in IT and OT. The different needs in IT and OT can easily lead to challenging technical conflicts.
