About the Book

Cyber risk quantification (CRQ) is the practice of measuring cybersecurity risk with probabilities, ranges, and financial impact — not colors or guesswork. For too long, risk programs have relied on “high/medium/low” charts that fail to inform executives.
This book is a hands-on, plain-English guide that shows professionals how to build CRQ programs from scratch, run practical assessments in Excel, and use AI responsibly to accelerate analysis. Packed with case studies, templates, and step-by-step instructions, it transforms CRQ from intimidating theory into a tool any risk leader can apply.
