About
Can Yildiz – information security without the jargon
I advise companies where regulation, technology and business interests meet – and translate between all three.
- CISSP
- ISO 27001 Lead Auditor
- IT-Security Manager (TÜV)
My experience
Years of experience and my network in the security industry keep me close to trends and specialist fields. I have also worked on a wide range of projects that gave me deeper insight into current threats and taught me valuable lessons about implementing effective security strategies.
My certifications – the CISSP among them – make that expertise well-founded and verifiable. It allows me to make decisions that make sense technically as well as economically. I firmly believe that continuous learning and sharing knowledge are decisive for success in the fast-moving world of IT security.
For more than nine years I was responsible for complex security structures in large corporate environments. Today I bring that experience to organisations that are looking for pragmatic solutions instead of standard presentations.
What I stand for
Understandable
Security topics explained so that management and engineering share the same basis.
Prioritised
Not everything at once, but the right thing first – measured by risk.
Honest
Even when the answer is: you do not need this.
Sustainable
I build structures that keep running without me.
