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.
