The Alerts queue shows a list of alerts that were flagged from endpoints in your network. Alerts are displayed in queues according to their current status. In each queue, you'll see details such as the severity of alerts and the number of machines the alerts were raised on.

Alerts are organized in queues by their workflow status or assignment:

  • New
  • In progress
  • Resolved
  • Assigned to me
  • Suppression rules

To see a list of alerts, click any of the queues under the Alerts queue option in the navigation pane.


By default, alerts in the queues are sorted from newest to oldest.

Alert severity Description
Threats often associated with advanced persistent threats (APT). These alerts indicate a high risk due to the severity of damage they can inflict on endpoints.
Threats rarely observed in the organization, such as anomalous registry change, execution of suspicious files, and observed behaviors typical of attack stages.
Threats associated with prevalent malware and hack-tools that do not necessarily indicate an advanced threat targeting the organization.
Informational alerts are those that might not be considered harmful to the network but might be good to keep track of.

Reviewing the various alerts and their severity can help you decide on the appropriate action to protect your organization's endpoints.

Understanding alert severity

It is important to understand that the Windows Defender Antivirus (Windows Defender AV) and Windows Defender ATP alert severities are different because they represent different scopes.

The Windows Defender AV threat severity represents the absolute severity of the detected threat (malware), and is assigned based on the potential risk to the individual machine, if infected.

The Windows Defender ATP alert severity represents the severity of the detected behavior, the actual risk to the machine but more importantly the potential risk to the organization.

So, for example:

  • The severity of a Windows Defender ATP alert about a Windows Defender AV detected threat that was completely prevented and did not infect the machine is categorized as "Informational" because there was no actual damage incurred.
  • An alert about a commercial malware was detected while executing, but blocked and remediated by Windows Defender AV, is categorized as "Low" because it may have caused some damage to the individual machine but poses no organizational threat.
  • An alert about malware detected while executing which can pose a threat not only to the individual machine but to the organization, regardless if it was eventually blocked, may be ranked as "Medium" or "High".
  • Suspicious behavioral alerts which were not blocked or remediated will be ranked "Low", "Medium" or "High" following the same organizational threat considerations.

Detection source

  • Windows Defender AV
  • Windows Defender ATP
  • Windows Defender SmartScreen
  • Others


The Windows Defender Antivirus filter will only appear if your endpoints are using Windows Defender Antivirus as the default real-time protection antimalware product.


  • Flat view - Lists alerts individually with alerts having the latest activity displayed at the top.
  • Grouped view - Groups alerts by alert ID, file hash, malware family, or other attribute to enable more efficient alert triage and management. Alert grouping reduces the number of rows in the queue by aggregating similar alerts together.

The grouped view allows for efficient alert triage and management.

Use the Alert management pane

Selecting an alert brings up the Alert management pane where you can manage and see details about the alert.

    • APT
    • Malware
    • Security personnel
    • Security testing
    • Unwanted software
    • Other
  • Assign the alert to yourself if the alert is not yet assigned.
  • View related activity on the machine.
  • Add and view comments about the alert.


You can also access the Alert management pane from the machine details view by selecting an alert in the Alerts related to this machine section.

Use the User details pane

Selecting a user brings up the User details pane where you can see information such as machine details, related alerts, last IP address, when the machine was first and last seen reporting to the service, and information on the logged on users.
