The CyberSecurity Leadership Handbook for the CISO and the CEO - Updated Edition: How to Fix Decade-Old Issues and Protect Your Organization from Cyber Threats

The updated and expanded edition of the "Cybersecurity Leadership Handbook for the CISO and the CEO" released in February 2023

📘 Book Description

Many organizations continue to suffer major data breaches—even while investing heavily in tools and technology. The missing piece? Leadership, governance, and strategy. In The CyberSecurity Leadership Handbook for the CISO and the CEO, JC Gaillard brings together over 100 curated articles (from 2015–2024) to help executives confront the underlying root causes of repeated cyber failures.

This updated edition offers a unique, holistic perspective for both technical and non-technical leaders, bridging the gap between boardrooms, C-suites, and security teams. It explores how legacy flaws, cultural misalignment, and organizational dynamics sabotage even the best technical defenses—and shows you how to break the cycle.

Inside, you'll discover:

- How old, unresolved security debts and legacy architecture create structural risk

- Why the “tech fix” mindset fails without governance and accountability

- Ways to align CISOs, CEOs, and Boards around a shared vision of security

- Leadership patterns that turn security into a strategic business enabler

- Concrete tools, frameworks, and lessons drawn from decades of experience

- Steps for building sustainable cyber resilience across organization, process, people, and culture

This is not a manual of security products—it’s a leadership handbook. It’s meant for executives who understand that cybersecurity is a business issue, not just a technical one.

🎯 Who Should Read This Book

- CISOs, Security Leaders, Heads of Risk & Compliance

- CEOs, CIOs, CTOs, COOs—any executive responsible for digital strategy

- Board members seeking better oversight of cyber risk

- Consultants, advisors, and transformation leaders in cybersecurity

- Senior IT and security professionals transitioning into leadership roles
