To address this challenge, and to reduce the volume of alerts that must be investigated individually,  Microsoft Defender ATP includes automated investigation and remediation capabilities. 
 
 Automated investigation leverages various inspection algorithms, and processes used by analysts (such as playbooks) to examine alerts and take immediate remediation action to resolve breaches. Automated investigation and remediation capabilities significantly reduce alert volume, allowing security operations experts to focus on more sophisticated threats and other high value initiatives. The **Automated investigations** list shows all the investigations that were initiated automatically, and includes details, such as status, detection source, and when each investigation was initiated.
