Microsoft Defender for Office 365 (formerly Office 365 Advanced Threat Protection) supports priority accounts as system tags that can be used in filters in alerts, reports, and investigations. Some users can also have access to critical tools and information, making them targets, as well.
To start with, we’ve announced two capabilities: priority account protection and premium mail flow monitoring. To help IT ensure a high quality of service and protection for these people, we have introduced capabilities in Microsoft 365 that enable an admin to tag specific users as priority accounts and then leverage app-specific features designed for them. Many organizations have people that are considered priority accounts for IT, such as executives, leaders, managers, and others.
