About

15+ years securing Saudi Arabia's most critical financial institutions — from founding a startup to leading cyber risk at the executive and board level. My career spans the full arc of cybersecurity leadership: -building and running a 80+ persons security organization at SNB -serving as CISO at Saudi Investment Bank, -and being a CCRO at STC Bank — where I owned enterprise-wide cyber risk, supporting digital risk control functions, and operational resilience co-ownership across the first licensed Fintech in Saudi and leading the transformation journey to being the first bank to transform from Wallet to a Bank. Beyond the executive role, I founded SIYEB Platform — a GRC SaaS solution that was later acquired — and today I invest in and advise early-stage technology ventures as an Angel Investor, with board membership at Jodr Technologies creating new ecosystems disrupting the industry of cybersecurity with an added value. My focus: cyber risk · digital risk · operational resilience · entrepreneurship.
