Michael Lines

Michael is a cybersecurity and risk executive, philosopher, and author whose work bridges the gap between digital security and the timeless principles of ethical leadership and strategic thinking.

With over 25 years of experience as a Chief Information Security Officer (CISO), advisory practice leader, and security consultant, Michael has helped organizations navigate the evolving landscape of cyber threats, governance, and risk management. His insights into why security programs fail—and how to make them succeed—have made him a trusted voice in the field.

Beyond information security, Michael explores philosophy, virtue ethics, and decision-making—applying ancient wisdom to modern leadership and risk management. His writing, speaking, and interviews challenge readers to think critically about the moral and strategic dimensions of cybersecurity, governance, and resilience.

His books provide both a practical and philosophical lens on security, risk, and virtue, equipping leaders with the tools to fortify their organizations and themselves against deception, failure, and moral compromise.

When he’s not writing, Michael continues to advise businesses, speak at industry events, and explore the intersections of security, ethics, and resilience.
