ABOUT US
We are CYBERSHIELD
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.
Neben seinen technischen Aufgabenbereichen ist er besonders in der Gestaltung und dem Aufbau des Trainingsbereiches von CyberShield aktiv. Extrem hilfreich erweist sich hier sein Staatsexamen (Lehramt). Während seines Studiums hat er an der Hochschule Heidelberg gemeinsam mit der IT-Abteilung an sicheren Netzwerken für Lehrende und Studierende gearbeitet und dieses Feld betreut.
Durch CyberShield konnte er dieser Leidenschaft stärker nachgehen als er sich je hätte vorstellen können.
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."

Serhii Salii
Head of Sales
Serhii leads our sales team and accompanies companies on their way to sufficient cybersecurity. He analyzes your individual challenges, identifies the best solutions and develops a strategic allocation of resources. This will help you strengthen your security position and achieve your cybersecurity goals efficiently.
He has extensive experience in industrial security (Aviation Engineering, Industrial Automation) and has worked for many years in both system engineering and sales.
When work is your passion, the line between professional and personal time is often blurred. When you meet Serhii outside working hours, he is probably spending time with his family, riding his bike or car, programming solutions for his IoT devices at home or building models of modern airplanes.
Quote: I would like to quote a question here: “If I have a locked door, can no one rob my house?”. As an expert, you have to be honest here and clearly point out that everything can be cracked, the only question is with what effort. This also applies to cybersecurity. The aim should therefore not be to become unbreakable, but to make it so difficult for the attacker that he loses the interest.
Certifications:
- ISO 27001 Lead implementer
- CISA 301v, 401v
- Fortinet Network Security Expert Level 3: Certified employee (NSE3)
