Marius Bindner Informationssicherheits-beauftragter

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.

Nicole Metz IT | ISMS

We were very impressed by greenhats' thorough and professional approach. The detailed reports and recommendations provided to us were extremely helpful in addressing the vulnerabilities and strengthening our security measures.

Dirk Schomber Leiter Organisation und Entwicklung IT

My first contact with greenhats was a stroke of luck when dealing with 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 division manager for IT and data security at the Engel Group, I relied on the knowledge of greenhats. Uncomplicated and professional - an invaluable partnership.
