Innovative projects and engagement for the new recruits

Weihrich Informatik was awarded 2012 with the Studerus Project Award, an award presented annually by the Studerus AG for an unusual project in the world of information technology. In this case Weihrich Informatik received the award for the design and implementation of a technically demanding LAN-/WLAN-equipment for a company location in Africa. In addition to geographical features in the project, the focus was on the integration of a mobile storage solution and on the security requirements of three different user groups.
In 2013 the team of Weihrich Informatik was honored to recieve the price for the second time. The submitted project convinced the jury as "the high expectations of the customer were met in an innovative and unique way by using a wide variety of networking products". Separate networks help the customer to obtain an optimum security while glass fiber helps to provide a high performance and the network has an overall high availability.
As we are concerned about the formation of junior staff, we have been instructing trainees in the division of IT already for several years now. In addition, Thomas Weihrich officiates as an expert for the exams of the practical work at the end of the apprenticeship.
