In Microsoft 365 organizations with Microsoft Defender for Office 365 Plan 2, priority account protection is a differentiated level of protection that's applied to accounts that have the Priority account tag applied to them. For more information about the Priority account tag and how to apply it to users, see Manage and monitor priority accounts.
Priority account protection offers additional heuristics that are tailored to company executives that don't benefit regular employees. Priority account protection is better suited to the mail flow patterns of company executives based on extensive data from the Microsoft datacenters.
By default, priority account protection is turned on in organizations with Defender for Office 365 Plan 2. This default behavior means an account that's tagged as a Priority account automatically receives priority account protection.
This article describes how to confirm that priority account protection is turned on, how to turn it on, and identifies the reporting features that allow you to see the results of priority account protection.
What do you need to know before you begin?
You open the Microsoft 365 Defender portal at https://security.microsoft.com.
You need to be assigned permissions before you can do the procedures in this article. You have the following options:
- Exchange Online RBAC: Membership in the Organization Management or Security Administrator role groups.
- Azure AD RBAC: Membership in the Global Administrator or Security Administrator roles gives users the required permissions and permissions for other features in Microsoft 365.
As previously described, priority account protection is applied to accounts that have the Priority account tag applied to them. For instructions, see Manage and monitor priority accounts.
The Priority account tag is a type of user tag. You can create custom user tags to differentiate specific groups of users in reporting and other features. For more information about user tags, see User tags in Microsoft Defender for Office 365.
