The history of Guntermann & Drunck GmbH

What began in 1985 with the development of products for software training has today grown into one of the leading high-end manufacturers in the KVM industry. The long-term entrepreneurial perspective, the economic stability as well as the reliability of our statements have always been our focus.

We have not only experienced the decisive developments in our industries first-hand, but have also played an active role in shaping them. We have further strengthened our leading position by consistently expanding the KVM product range and by forward-looking developments such as the first modular matrix switch in 1994.

Over the years, KVM systems became more powerful and installations more complex. Starting in 2003, the first extenders were introduced that could transmit digital video signals over distances of up to 10,000 meters, and this technical progress continued with the development of digital matrix switches. As of 2017, the topic of KVM-over-IP gained increasing importance. The first extender system for unlimited computer access via IP structures was followed shortly after by the first IP matrix.  

Today, thanks to a high level of solution expertise and relevant product developments, G&D is one of the world's leading manufacturers of KVM solutions and has the broadest, interoperable product portfolio on the market.


Strong employee retention, a powerful partner network and a high degree of customer loyalty are only a few of the strengths that make Guntermann & Drunck a reliable partner for KVM solutions.
