About Christoph

Expert for IT security and IT infrastructure with a pronounced hands-on mentality. I am happy to support not only in finding solutions but also, upon request, to take over the implementation and IT project management.
In addition to IT infrastructure design and architecture, I also support in areas such as Microsoft Azure, cloud architecture, hybrid infrastructures, as well as software deployment and automation. I apply IT security automatically by design or, upon request, create targeted cybersecurity reviews of the environment.
