+# Use sensitivity labels to investigate incidents  
+
+**Applies to:**
+
+- [Microsoft Defender Advanced Threat Protection (Microsoft Defender ATP)](https://go.microsoft.com/fwlink/p/?linkid=2069559)
+
+A typical advanced persistent threat lifecycle involves data exfiltration. In a security incident, it's important to have the ability to prioritize investigations where sensitive files may be involved so that corporate data and information are protected.
+
+Microsoft Defender ATP helps to make the prioritization of security incidents where sensitive information are involved easier with the use of sensitivity labels.
+
+1. In Microsoft Defender Security Center, select **Incidents**. 
+
+2. Scroll to the right to see the **Data sensitivity** column. This column reflects sensitivity labels that have been observed on machines related to the incidents providing an indication of whether sensitive files may be impacted by the incident.
+
+3. Open the incident page to further investigate. 
+
+4. Select the **Machines** tab to identify machines storing files with sensitivity labels.
