Microsoft 365 is a complex, comprehensive, ever-evolving, and expanding suite, or collection of products, covering broad aspects of cloud computing, work, communication, and collaboration. In summary, it is huge, and it is always changing. You know what they say about cloud and cloud-related products – the only constant thing is change! Microsoft 365 and its related products and features are not an exception to this rule or saying. We wanted to include in the book everything that has anything to do with security and compliance in Microsoft 365, and we were very enthusiastic, motivated, and thrilled. However, it was easier to say and wish than to make it happen. There was – and still is – simply too much to include, too many features, products, capabilities, and so many things to mention, introduce and explain.

We tried to focus our time and energy on addressing all changes, ultimately deciding to bring you the most valuable and useful security and governance knowledge from our day-to-day, real-life, hands-on working experience with Microsoft 365. Compromises were made in what to include and what to leave out of the book, and we hope it will help you to sharpen your skills and become a better Microsoft 365 security and governance administrator, specialist, or user.
