Since the beginning of 2024, Florian Wolf is managing partner at Ceritutde Consulting, responsible for sales and the development of sustainable customer relationships.
Several years of project management in complex IT infrastructure environments combined with 20 years of sales and product experience have given him a comprehensive skillset in the areas of project management, sales, IT and IT security, where the focus is always on success for the customer.

Subsequently, Marc Nimmerrichter worked for several years both independently and as a senior consultant for a Viennese consulting firm. In his many years of consulting experience, he has worked for well-known software developers, IT service providers, financial service providers and federal authorities in Austria, Germany, Luxembourg and Belgium. His technical expertise, extensive consulting experience and ongoing technical training enable him to make competent and factually correct assessments of security risks, ensuring the best possible course of action is taken.
