About the Book

Digital Operational Resilience is the book regulators didn't write for you. DORA governs every financial entity and ICT provider doing business in the EU — but the text itself reads like what it is: a regulation, not a guide. This handbook closes that gap. Mapped chapter-for-chapter to DORA's own nine-chapter structure, it works through what each obligation actually requires in practice: the ICT risk management framework your board has to own, the incident-reporting clock that starts the moment something breaks, the Register of Information every risk manager ends up maintaining whether or not it's officially their job, and the Lead Overseer regime now watching the critical providers underneath you. Built from real supervisory experience, real enforcement cases, and a worked case study carried through the book's core chapters — the practitioner's answer to "what do I actually do about it," not a restatement of the regulation.

About the Author

William Power

William Power is an enterprise architect and technical auditor with over two decades of hands-on experience designing and securing production systems for regulated industries. He holds a Higher Diploma in Governance, Risk and Compliance (HDip GRC) and founded Powerworks Consulting, where he audits AI and cloud architectures against DORA, the EU AI Act, and NIS2 not from a policy binder, but from the actual code, infrastructure, and deployment pipelines regulators expect organizations to get right. This book draws directly on that practice: the gap between what DORA requires on paper and what it actually takes to prove it in production.
