Über Rafal

"Full-Stack" IT Security & GRC Professional with 25 years of experience in IT and information security—from hands-on implementation to strategic governance.

Demonstrated expertise in elevating IT security maturity and cyber resilience based on recognized frameworks including ISO/IEC 27001, BSI IT-Grundschutz, NIST, and ITIL. As a "Full-Stack" expert, I operate seamlessly across technical implementations (Security Architecture, IAM, PKI, Cloud Security) and GRC domains (Audits, Risk Management, Compliance, Data Privacy, NIS-2, DORA, CRA).

Comprehensive experience in security architecture, audit preparation, ISMS consulting, and project delivery within regulated environments, EU projects, and cloud infrastructures. Deployable as Interim CISO/ISO, IT Security Architect, or GRC Consultant.

The "Full-Stack" approach enables me to serve as an effective bridge between technical teams, management, and external stakeholders.
