From the very first meeting with greenhats GmbH, we were convinced that we had found the right service provider for our company. We worked together as a team right from the start and were able to achieve a great result for both sides.

Our first contact with greenhats was a lucky coincidence when it came to overcoming the HAFNIUM security gap in 2021. As a project manager at an IT service provider, I was impressed by their expertise. In my new role as Head of IT and Data Security at the Engel Group, I relied on the expertise of greenhats. Uncomplicated and professional - an invaluable partnership.
