Beschreibung

Interim CISO and Senior Information Security Consultant with 20+ years of experience in cybersecurity, IT security and governance. I help organizations design, implement and improve security structures that are practical, audit-ready and aligned with business needs.

My expertise includes ISO 27001, ISMS, risk management, security governance, audit preparation and interim security leadership. I support clients in regulated and complex environments, including projects related to BSI IT-Grundschutz, TISAX, KRITIS, PCI DSS, GDPR, GxP and SOX.

I work with leadership teams, IT organizations and compliance stakeholders to establish clear security roadmaps, governance models, policies and operating procedures. My goal is to turn security requirements into effective structures that improve resilience, transparency and execution.

Typical assignments include ISMS build-up, security strategy, governance design, certification readiness, policy development and support for security transformation initiatives.
