Microsoft 365 is a powerful platform for email, collaboration, and data storage.
However, many businesses do not configure it securely, leaving them exposed to data loss and cyber threats.
This page explains how Microsoft 365 works, the risks to be aware of, and how to secure your environment properly.

It enables businesses to work securely from anywhere—but only when properly configured.
