Cybersecurity leadership and architecture for complex IT environments

I support organizations in strengthening and securing complex IT environments, combining hands-on expertise with executive-level advisory. As an independent cybersecurity consultant, I work with organizations facing complex, security-critical challenges, particularly in enterprise and regulated environments with a strong on-premise footprint.

My focus is on security architecture, risk reduction, and the stabilization of critical systems. I am typically engaged when security becomes a business-critical concern, internal teams reach their limits, or experienced leadership is required without a permanent hire.

Confidentiality is fundamental to all engagements. All inquiries are handled with discretion. Secure communication via PGP or S/MIME is available on request.
