As an engineering company for digital solutions and processes, the security of applications and infrastructure has been a central topic for many years and is always in the focus of our projects and our own IT security... As a participant in the Alliance for Cyber Security of the Federal Office for Information Security and a member of ISACA, IT security and the data protection often associated with it is a cornerstone of our actions.

For our customers we have created a SECURITY GRID to reduce the attack surface of applications and IT infrastructures and to actively prevent attacks. Together with you, we analyze your security needs and build a wall from our building blocks that creates more strategic security and availability and thus a clear competitive advantage for your company.
