About Thomas

I have been working in IT security for over 25 years, as well as in the implementation of GRC strategies and regulatory frameworks such as ISO 27001, NIST 800-171, and GDPR. I am applying with great interest for the position of GRC Consultant / ISO 27001 Lead Auditor in your company. I have led and successfully audited international projects for public clients and companies – including security-critical infrastructures according to US and European standards.

As a certified CISSP and ISO/IEC 27001 Lead Auditor, I have established ISMS structures worldwide, implemented cloud and IAM solutions, and defined compliance processes from scratch. In my last project, I was responsible as Cybersecurity Lead for the setup of an auditable infrastructure according to NIST 800-171 and ISO 27001 – including SOC/NOC, Incident Response, and OT/IT segmentation.
