+### New security posture assessment: Prevent Certificate Enrollment with arbitrary Application Policies (ESC15)
+
+Defender for Identity has added the new **Prevent Certificate Enrollment with arbitrary Application Policies (ESC15)** recommendation in Microsoft Secure Score.
+
+This recommendation directly addresses the recently published [CVE-2024-49019](https://msrc.microsoft.com/update-guide/en-US/advisory/CVE-2024-49019), which highlights security risks associated with vulnerable AD CS configurations. This security posture assessment lists all vulnerable certificate templates found in customer environments due to unpatched AD CS servers.
+
+The new recommendation is added to other AD CS-related recommendations. Together, these assessments offer security posture reports that surface security issues and severe misconfigurations that post risks to the entire organization, together with related detections.
