Compliance considerations:

Area Explanation
Does the change store new customer data? Microsoft Defender and Intune features may generate and store additional security telemetry, alerts, and device analytics data as part of normal service operation.
Does the change alter how existing customer data is processed, stored, or accessed? Microsoft Defender enhancements introduce additional scanning and analysis of email content and URLs, including time-of-click protection, increasing inspection of existing data for threat detection.
Does the change introduce or significantly modify AI/ML capabilities? Microsoft Defender for Office 365 uses machine learning to detect phishing, malware, impersonation, and zero-day threats, and these capabilities are expanded through this rollout.
Does the change alter how admins can monitor, report on, or demonstrate compliance activities? New alert types and threat detection insights will appear in the Microsoft Defender portal, impacting security monitoring and reporting.
Does the change add any integration to 3rd party software products? Intune ServiceNow integration is included.
Does the change include an admin control and can it be controlled through Entra ID group membership? Admins can configure Defender and Intune policies and apply settings using user and group-based assignments.
