Book Description:
Modern organizations run on constantly changing endpoints, yet many teams still struggle to get the most out of Defender endpoint security. Coverage gaps, noisy detections, mixed platforms, and unclear device behavior often get in the way of effective prevention, detection, and response.
This second edition helps you tackle those challenges directly. Updated for today's Defender endpoint security, and the broader Microsoft Defender ecosystem, it shows how MDE works across clients, servers, and now mobile devices, and how to align deployments with real-world constraints. New chapters on mobile threat defense, production rollout, and tuning provide practical guidance for moving beyond pilot environments, handling edge cases, and protecting critical and legacy assets.
Throughout, the book brings together IT and SecOps viewpoints to help you operate Defender for Endpoint with more clarity and less friction. You'll learn how to maintain sensor health, interpret incidents confidently, reduce noise without weakening protection, and troubleshoot recurring issues.
Whether you're refining an existing deployment or planning a new one, this edition gives you a clearer path to making Defender for Endpoint a reliable part of your security program.

Campbell, Ru: - Ruairidh (Ru) Campbell is a Microsoft MVP and Microsoft Security Practice Lead at Threatscape. There, he heads up a team of award-winning Microsoft security pros, and development of Overwatch, a Microsoft 365-centric security posture platform addressing the challenges of Entra, Defender, Intune, Purview, and Copilot. In the cybersecurity community, Ru runs the Microsoft 365 Security & Compliance user group and his blog, regularly speaks at other user groups and conferences, and publishes technical deep dives on YouTube. Ru holds a B.Sc. (Distinction) in computer networking from the University of the West of Scotland and, away from cybersecurity, spends his time with his wife and daughter (who he's trying, with mixed results, to grow into a fellow metalhead).
Hoyle, Ian: - Ian Hoyle worked in the IT field for over 30 years, since the inception of the internet in Australia, as a research scientist, a principal infrastructure architect at the world's largest mining company, and more recently at Microsoft, holding a number of technical roles, finally as a senior security technical specialist. His interest in IT security was triggered by a visit to Israel in 2016 for the internal launch of Seville, called Windows Defender Advanced Threat Protection on release. That moment changed his working career, thereafter completely focusing on Defender security. He received two BSc (Hons) degrees in theoretical physics and geophysics too long ago (!!) and then went on to receive a Ph.D. in geophysics. Like so many people in engineering and science, he ended up in IT and in the security field, which he loves.
Snow, Paul: - "With more than 20 years of industry experience and relevant certifications, Paul (Huijbregts) Snow has a long history of working with customers across the world, leveraging his passion for (Microsoft) security solutions - and being brutally honest about them. Working at Microsoft as a Principal Product Manager, he remains a seasoned technologist and a subject matter expert in endpoint and cloud security. He currently spearheads a team of product managers developing endpoint security features and solutions across operating systems and environments, focusing primarily on management and deployment. His motto is: "I drink beer and I know Microsoft security things.""
