A hopeful guide to the decisions only leaders can make. Boards are asked to govern cyber risk through dashboards, incident plans and investment papers. Yet the question that matters most is simpler: which promises become impossible when digital systems fail?Cyber Stewardship follows a composite international board from a reassuring green dashboard into ransomware, a hard extortion decision, an acquisition carrying someone else's digital past, geopolitical pressure and the arrival of AI, robotics, nanotechnology and quantum computing.
Alongside the narrative, brief windows into the public record - Maersk, SingHealth, Colonial Pipeline, the British Library, CrowdStrike and others - show what real organisations have chosen to disclose, and what boards can responsibly learn from them. Inside, board members and executives learn to connect cyber choices to people and purpose, challenge evidence without becoming specialists, fund resilience and rehearse hard decisions, govern suppliers and emerging technology, and preserve truth, practical autonomy and long-term trust after something goes wrong.
Written for the European reality of NIS2, DORA and the AI Act. Every chapter closes with board-ready questions and a practical Monday move, while twelve ready-to-use board tools support action. For chairs, non-executive directors, executives and the security leaders who brief them.
