Is anyone here familiar with players on the German market and can recommend MSPs that offer Managed Cloud Services, Managed Security or Managed Workplace Services?

Question

Hi everyone! We are a young, dynamic company and wanted to outsource our IT in a timely manner. We are basically new to this subject - we are familiar with Managed Cloud Services, Managed Security and Managed Workplace. In order to specifically serve these services, various companies have been suggested to us via the partner search - our question: Does anyone here know about outstanding players on the German market and can recommend a few companies / managed service providers to us? Any help will be appreciated and will help a lot!
