Visit the Microsoft 365 Defender portal
The Microsoft 365 Defender portal (https://security.microsoft.com) is your one-stop shop for using and managing Microsoft Defender for Business. It includes callouts to help you get started, cards that surface relevant information, and a navigation bar to give you easy access to various features and capabilities.
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.
|Home||Takes you to your home page in the Microsoft 365 Defender portal. 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. To learn more, see Security recommendations - threat and vulnerability management.
|Incidents||Takes you to your list of recent incidents. As alerts are triggered, incidents are created. An incident can include multiple alerts. Make sure to review your incidents regularly.
To learn more, see View and manage incidents in Defender for Business.

To learn more, see Review remediation actions in the Action center.

|More resources||Navigate to other portals, such as Azure Active Directory. But keep in mind that the Microsoft 365 Defender portal should meet your needs without requiring you to navigate to other portals.|
