Top performance confirmed - SITS Deutschland receives consultant seal of excellence

Convincing with expertise in consulting: SITS Deutschland GmbH is one of the best SME consultants in Germany and has therefore been awarded the TOP CONSULTANT Seal 2024. The former German President Christian Wulff handed the trophy over to SITS Deutschland on Friday, the 28th of June, in Weimar. Wulff supports the consultancy competition as a mentor. On behalf of compamedia, the Wissenschaftliche Gesellschaft für Management und Beratung (WGMB) had previously examined how good the participants were at advising their SME clients.

The heart of TOP CONSULTANT is a scientific customer survey: Medium-sized companies that had previously worked with SITS Deutschland were surveyed by the WGMB. The reference customers named by SITS Deutschland stated, for example, whether and to what extent they were satisfied with the consultancy service and whether they would recommend SITS Deutschland to others (further information on the test criteria can be found at

SITS Deutschland is one of the Top Consultants 2024 thanks to its excellent consulting quality. Even before the company was founded in 2020, the Wiesbaden-based consultants had already established a reputation for their expertise in the field of digital transformation, particularly in the areas of IT and information security, data protection and compliance as well as secure working in the cloud. Today, SMEs and public authorities also benefit from the know-how that the consultants gained back then while working with “the big players”. “We have standardized a lot so that we can also provide IT security that meets high legal requirements for medium-sized customers with a limited budget,” explains Ralf Wecke, Director Public, who is delighted to have been awarded the TOP CONSULTANT seal once again. A detailed portrait of SITS Deutschland GmbH can be found on the online portal

Prof. Dr. Dietmar Fink, Professor of Management Consulting at Bonn-Rhein-Sieg University of Applied Sciences, leads the Wissenschaftliche Gesellschaft für Management und Beratung (WGMB) together with Bianka Knoblach. They decide who is awarded the TOP CONSULTANT seal. At the award ceremony, Professor Fink emphasized that the award is a valuable orientation aid: “The seal, which is essentially based on a customer survey, provides SMEs that are looking for advice with a recommendation as to where SME-related expertise is particularly pronounced.”
