About Ethan

Is your organization navigating DORA, NIS 2, the EU AI Act, or FINMA compliance while trying to build a resilient security architecture?
I help CISOs, CIOs, and executive teams turn complex regulatory pressure into structured, actionable security programs.
With 15 years of cybersecurity leadership across financial services, energy, and management consulting — including 5 years as Senior Manager at PwC France — I bring a rare hybrid expertise that combines three capabilities most consultants deliver separately: strategic GRC leadership, hands-on security architecture, and end-to-end project delivery.
What sets me apart is my depth in AI Security: I design LLM governance frameworks aligned with NIST AI RMF and EU AI Act, and I conduct adversarial testing of AI systems — a niche few senior profiles can offer.
Typical engagements include: fractional/virtual CISO missions, Zero Trust & cloud security architecture (AWS, Azure, GCP), large-scale TPRM programs (1,400+ vendor assessments/year at PwC), DORA/FINMA/NIS 2 compliance roadmaps, SOC design and deployment (IT & OT/ICS), and C-suite security reporting via Power BI dashboards.
Advanced training completed: CISSP · CISM · CISA · CRISC · CCSP · TOGAF · CEH · CARP · CAISP · AIGP · OSCP
Based in Gaillard (74), 15 min from Geneva — available for Swiss, French, and international remote contracts
