Client Voices
We let our work speak through the voices of those we've partnered with. See below.
Yuri Volosenko
CTO Metro
I've been working with Christian in different ways since 2013 — and simply trust nobody more in this domain. Highly recommended!
Caroline Theißen
Executive Director Hypoport hub
Delivering cybersecurity for a network of 20+ Hypoport portfolio companies is no easy job — especially when each company operates autonomously. CISOIQ has built a security program that scales across this diversity, driving a global optimum while respecting local realities and culture.
Mark Göring
Managing Director Hasomed-Tech
What I value most about CISOIQ is how seamlessly they integrate with our tech team. Nothing they do is copy&paste — every control, every process is built around our specific environment. When you're trusted with millions of patient's health data records, that level of precision and partnership makes all the difference.
Anselm Bauer-Wohlleb
Co-Founder & CTO Alasco
Absolutely a fun team to work with! Going with this team was definitely faster and more efficient than hiring an in-house security team. You feel their experience right away — they've seen enough of companies from the inside and know what works.
Christian Schneider-Sickert
Managing Director, LIQID
These guys are pragmatic - They obviously understand security, but most importantly, they understand business context. In the due diligence leading up to our last financing round, even large institutions were impressed with the quality of their work.
Karl Markgraf
COO TeamViewer
Great CISOs that deliver are rare - We thank Christian and his team for running point on our security program and supporting us for several years in building up best-in-class defense capabilities.
