Jake_Mowrer Hello, this app is not supported by Splunk, we tried to explain it to Microsoft support several times.

Apps and add-ons published either by Splunk or third-party developers. Indicates that no support or maintenance are provided by the publisher.
Customers are solely responsible for ensuring proper functionality and version compatibility of Not-supported apps and add-ons with the applicable Splunk software. If unresolvable functional or compatibility issues are encountered, customers may be required to uninstall the app or add-on from their Splunk environment in order for Splunk to fulfill support obligations.

Are you aware of this?
Thank you

  rs8091 - Thank you for your comments.
  
  The Splunk supported Microsoft 365 Defender Add-on for Splunk will be released in the near future.
  
  We'll announce it and news about other SIEM connectors here in the Tech Community.
  
  Thanks,

  Yes, we're definitely aware of this and we're working with Splunk to improve this. Are you running into an issue with the add-on?

    Jake_Mowrer the app is working but our team does not want to put in production the unsupported app because they are afraid it can stop working any time. Is there a timeline for fixing this?
    
    An alternative from the support is to use the graph api (https://graph.microsoft.com/v1.0/security/alerts/ with app: https://splunkbase.splunk.com/app/4564/ ) but we don't see the same level of detail of the incident API.
    "IncidentURI" is missing and also useful fields like "Veridict", "InvestigationState"

Jake_Mowrer Yes we installed this addon but there some issues:

these fields are not available anymore. (while were available with different app/API)
IncidentLinkToMTP
IncidentLinktoWOATP
RemediationAction
RemediationIsSuccess

We already opened a case with Microsoft support but we are not able to resolve this. This is the reason we are asking if other customers are successful with this integration or not.

  rs8091 Those fields are from the SIEM API documented here:
  Microsoft Defender for Endpoint detections API fields | Microsoft Docs
  
  The 1.3.0 Add-on for Splunk is using the incident API in M365 Defender and the Alert API in Defender for Endpoint (you can set it up for both) and not the SIEM API:
  
  M365 Defender incident API - List incidents API in Microsoft 365 Defender | Microsoft Docs
  
  Defender for Endpoint API - List alerts API | Microsoft Docs
  
  The fields you are looking for are a bit different now:
  
  M365 Defender incident API:
  
  - IncidentLinktoMTP = incidentUri (M365 Defender incident API)
  - RemediationAction and RemediationIsSucess changed to:
  
  detectionStatus, remediationStatus, remediationStatusDetails
  
  Thanks,

    Jake_Mowrer Thank you for the clarification. I can confirm that from incident API we can see the link.
    We are surprised that link to the alert was removed from SIEM API. It's an important information to have for a security analyst.
    We opened a support case to investigate this
