I've been working with Christian in different ways since 2013 — and simply trust nobody more in this domain. Highly recommended!

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.

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.

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.

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.
