Christian Schlehuber

Managing Partner / Lead OT Security Expert

Christian is the founder and managing partner of CyberShield. He is responsible for our teams and projects. He also supports our customers from the development and execution of security programs to engineering in the concrete implementation of measures.

Prior to joining CyberShield, Christian worked in critical infrastructure protection research for TU Darmstadt. After moving to Deutsche Bahn, he developed the security architecture for DB Netz AG’s digital interlocking before working in security management for both DB Netz AG and DB AG. He is the founder of the European Rail Information Sharing and Analysis Center (ER-ISAC) and leads WG 26 of CENELEC TC 9X as convenor, which developed TS 50701 (Railway Applications – CyberSecurity).

In his spare time, Christian can often be found doing sporting activities such as a marathon or alpine mountaineering (-he quickly swapped his Newton running shoes for crampons and an ice axe). He also enjoys traveling with the company’s two mascots, Ben and Whisky.

Quote: “CyberSecurity doesn’t look like a selling point at first glance, because it neither generates greater profits nor increases the capacity of a system. However, on closer inspection, it is an enabler for many digital and innovative trends I currently see. It ensures that we can experience digital transformation without fear that attackers will have an easy game.”

Gunter Hochsteiner

Manager Training Service / Technical Consultant Cybersecurity

Gunter leads the project for the development of the Hardening OT Baselines / Guidelines. He also supports customers in setting up their security programs, analyzes audit findings and improves security in the OT and IT areas with his team.

In addition to his technical responsibilities, he is particularly active in designing and building CyberShield’s training division. His state examination (teaching profession) proves to be extremely helpful here. During his studies at Heidelberg University, he worked with the IT department on secure networks for faculty and students and supervised this field.
Through CyberShield, he was able to pursue this passion more than he could have ever imagined.

On weekends, you can find Gunter at the shelter in the morning walking a dog and in the gym in the afternoon using the equipment and free weight area.

Quote: IT security should be important for every company, as a deficiency in this sensitive field can have devastating consequences. These can go far beyond economic damage and can also extend to individuals and society. IT security affects everyone.
