 Before enabling Microsoft Defender for Identity, be sure you understand the architecture and can meet the requirements.
 
-Microsoft Defender for Identity uses machine learning and behavioral analytics to identify attacks across your on-premises network along with detecting and proactively preventing user sign-in risks associated with cloud identities. For more information, see [What is Microsoft Defender for Identity?](/defender-for-identity/what-is)
+Microsoft Defender for Identity is fully integrated with Microsoft Defender XDR, and leverages signals from both on-premises Active Directory and cloud identities to help you better identify, detect, and investigate advanced threats directed at your organization.
+
+Deploy Microsoft Defender for Identity to help your SecOp teams deliver a modern identity threat detection (ITDR) solution across hybrid environments, including:
+
+- Prevent breaches, using proactive identity security posture assessments
+- Detect threats, using real-time analytics and data intelligence
+- Investigate suspicious activities, using clear, actionable incident information
+- Respond to attacks, using automatic response to compromised identities. For more information, see [What is Microsoft Defender for Identity?](/defender-for-identity/what-is)
