This isn’t just a book. It is a roadmap for the next generation of cybersecurity leadership. In an era where cyber threats are more sophisticated and the stakes are higher than ever, Chief Information Security Officers (CISOs) can no longer rely solely on technical expertise. They must evolve into strategic business leaders who can seamlessly integrate cybersecurity into the fabric of their organizations.

This book directly addresses the increasing demands from boards and regulators in the wake of recent high-profile cyber events, providing CISOs with the necessary skills and knowledge to navigate this new landscape. This book isn’t just about theory but also action. It delves into the practicalities of business-aligned cybersecurity through real-life stories and illustrative examples that showcase the triumphs and tribulations of CISOs in the field. This book offers unparalleled insights gleaned from the author’s extensive experience in advising hundreds of successful programs, including in-depth discussions on risk quantification, cyber insurance strategies, and defining materiality for risks and incidents. This book fills the gap left by other resources, providing clear guidance on translating business alignment concepts into practice. If you’re a cybersecurity professional aspiring to a CISO role or an existing CISO seeking to enhance your strategic leadership skills and business acumen, this book is your roadmap. It is designed to bridge the gap between the technical and business worlds and empower you to become a strategic leader who drives value and protects your organization’s most critical assets.
