ABOUT US

We are CYBERSHIELD

Our strength lies in diversity and a pragmatic approach: A multicultural team where everyone contributes to the common mission with their unique experiences and specialised expertise. This diversity enables us to develop comprehensive and customised solutions that think outside the box. In doing so, we act independently and rely on transparency, deep trust and our continuous drive for further development. We see ourselves as an integral part of our clients' teams. By working closely together, we take the time to understand individual needs in their entirety.

Christian Schlehuber

Managing Director / Lead OT Security Expert

Christian is the founder and Managing Partner of CyberShield. He oversees our teams and projects. Additionally, he supports our clients from the development and execution of security programs to engineering in the concrete implementation of measures.

Before joining CyberShield, Christian worked in research on the protection of critical infrastructures for TU Darmstadt. After moving to Deutsche Bahn, he developed the security architecture for the Digital Signal Box of DB Netz AG 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 serves as Convenor of WG 26 of CENELEC TC 9X, which developed the TS 50701 (Railway Applications - Cybersecurity).

In his free time, Christian can often be found doing sporting activities such as marathons or alpine mountain tours (he quickly swapped his Newton running shoes for crampons and an ice axe). He also enjoys being out and about with his three furry friends Ben, Whisky and Gismo.

Quote: "At first glance, cybersecurity doesn't seem like a selling point because it doesn't generate greater profits or increase the capacity of a system. However, upon closer examination, it is an enabler for many digital and innovative trends that I currently see. It ensures that we can experience digital transformation without having to worry that attackers will have an easy time."

Gunter Hochsteiner

Manager Training Service / Technical Consultant Cybersecurity

Gunter leads the project for the development of the Hardening OT Baselines/Guidelines at our company. Additionally, he assists clients in establishing their security programs, analyzes audit findings, and, along with his team, enhances security in the areas of OT and IT.

In addition to his technical responsibilities, he is particularly active in shaping and developing the training area of CyberShield. His State Examination (Teaching Degree) has proven extremely helpful in this regard. During his studies at Heidelberg University, he worked with the IT department on secure networks for teachers and students and managed this field.
Thanks to CyberShield, he was able to pursue this passion more than he could ever have imagined.

On weekends, you can find Gunter in the mornings at the animal shelter walking a dog, and in the afternoons at the gym using the equipment and in the free weights area.

Quote: "IT-Security should be important for every company, as a deficiency in this sensitive field can have devastating consequences. These consequences can extend far beyond financial damages and also impact individuals and society. IT security concerns everyone."
