Rudolf Coetzee

At Violet Sky Security, I advise fintech, blockchain, and financial-sector clients across the US, EU, and Caribbean on GRC, security architecture, and blockchain security. I’ve built zero-trust programs, SIEM monitoring frameworks, cryptocurrency assurance services, and virtual CISO roadmaps across Azure, AWS, and GCP.

I recently led ISO 27001 implementation, GDPR data-protection work, threat modeling across 100+ repositories, security breach response, and DevSecOps maturity planning at FreedX. My work also includes DORA, MiCA, PSD2, NIS2, PCI DSS, and third-party risk programs for regulated financial services.

I publish research on privacy-preserving authorization, zero-knowledge compliance, agentic delegation, and post-quantum cryptography. I bring 31 years in IT and 22 years in security leadership, including work with ING Bank, ABN AMRO, Rabobank, BNP Paribas, FedEx Express International, and VodafoneZiggo.
