Just a few weeks after the project was completed, thanks to ProSec's pragmatic and solution-oriented report, we were able to carry out 80% of all recommended hardening and process optimization and are continuing to work efficiently and prioritized on the complete processing. Through the project, we not only gained technical know-how, but were also able to benefit from ProSec's experience on an organizational level. Nothing stands in the way of further collaboration on our part!

Ranger Marketing & Vertriebs GmbH is part of the Ströer Group and the European market leader for personal customer advice. Their customers include product partners such as Deutsche Telekom, E.ON and Vodafone Kabel Deutschland.

Information and data security are therefore of particular importance. That's why David Sandfort, as a cyber security officer, relies on the support of the specialists at ProSec to control and expand his IT security. We are proud to have already achieved many important goals for Ranger Marketing & Vertriebs GmbH in our collaboration so far!
