How to Build a Cybersecurity Program from Scratch | CISO Transformation Playbook

In this "Coffee with PRB" masterclass, veteran CISO Ilias (Group CEO, Cyber Shelter) explains how to build a cybersecurity program from scratch—starting with risk appetite, not policies—arguing security exists to enable the business 1:34.
Key Takeaways:
• Start with risk appetite—align security risk ratings with enterprise/operational risk so "critical" means the same to the board 26:57
• Prioritize gaps by risk and effort: P0 = high-risk gaps fixable quickly with existing tools; gaps needing procurement get temporary alternative controls 22:38
• Maximize existing tools before buying—most use under 30% of current controls' capabilities 50:40
• Tailor controls to the business—security failures come from process failure, not technology 13:15
• Win budget via one-page business-language dashboards; management responds to financial impact, not vulnerability counts 52:29
• Build step by step: risk appetite → gap assessment → risk-rating → prioritization → roadmap linking maturity targets to risk appetite 56:22
These frameworks come from practical experience, not books; CISOs who block business agility risk losing relevance—security's job is enabling the business.
