Applies to:

  • Windows 10

Microsoft Defender Antivirus protects tenants, users, and devices from software threats including viruses, malware, and spyware. It's robust, ongoing protection that's built into Windows 10 and included with Microsoft 365 Business Premium and Microsoft 365 E3.

To access the Threat management page in Microsoft 365 Lighthouse, select Threat Management in the left navigation pane to view your customer tenants' security posture against threats. You'll see tenants, users, and devices that require your attention and recommendations that will help you reduce risk.

Overview tab

On the Overview tab of the Threat management page, you can monitor the antivirus state across all your tenants to identify the areas that need attention.

Threats tab

On the Threats tab of the Threat management page, you can see the Active, Mitigated, Resolved, and Allowed threats across all your tenants. You can also remediate multiple threats at the same time across all your tenants by filtering and drilling down into each threat to learn which devices, users, or tenants are affected.

You can filter threats by:

  • Threat status
  • Threat severity
  • Threat type
  • Date range

The following table lists the different threat statuses and their definition:
