Digitalise safely

Our solutions for your applications

The pressure to digitalise the supply infrastructure is constantly growing. On the one hand, this is more frequently required by the relevant regulations (e.g. FFVAV). On the other hand, new market conditions, such as the energy transition and rising prices, require efficient grid operation and grid expansion, for which intelligent grids are needed. With the increasing digitalisation of the networks, there are also new dangers that need to be considered and secured. This means that there are completely new challenges for utilities that need to be mastered.
