The navigation bar

Use the navigation bar on the left side of the screen to access your incidents, view reports, and manage your security policies. The following table describes items you'll see in your navigation bar.

Item Description

The home page highlights any active threats that are detected, along with recommendations to help secure your company's data and devices. Recommendations are included in Defender for Business to save your security team time and effort. The recommendations are based on industry best practices.
