Microsoft 365 Security for IT Pros (2023 edition)

The Microsoft 365 Security for IT Pros e-book is the definitive guide to understanding and implementing Microsoft's security solutions. This is the third release of the book, and it continues to be the only resource of its kind, covering Microsoft security solutions in-depth, with regular updates and high praise from readers and industry experts.

Whether you're new to Office 365 and want to learn more about Microsoft's security offerings or have a background in security and want to explore Microsoft's capabilities, this book is for you. It provides a wealth of information on various products and services, while also taking into account the larger security landscape beyond Microsoft.

Last update: October, 2023

The current version of this edition ships with about 800 pages of practical information about Microsoft 365 and its various aspects. The book not only explains what Microsoft's security solutions are, but also provides practical guidance detailing how to configure and operate the different products and features along with real-world examples from the authors' vast experience working with customers across the globe. We have purposefully kept the page count around its current size so that it still remains digestible.

Because the book's contents are updated on a monthly basis, you will keep having up-to-date information, even as Microsoft's products change, or as they change names. Again. As you can imagine, this can be a huge time saver. We keep working hard to keep content fresh, so you don't have to.

When you purchase this book, you get the monthly updates until the next version is released. This will usually be after a year. Even after updates to this edition of the book stop, the information within remains valuable long after you first read it. Consider everything that is covered, that doesn't seem like a bad deal at all.

You can always download the latest files from your Gumroad account or by clicking the link in the receipt issued after you bought the book.
