Microsoft Application Protection Incidents
Hi, Seeing a small number of incidents within Sentinel with the Alert product name of 'Microsoft Application Protection'. Can view them in Sentinel but when clicking on the hyper link to be taken to the defender portal I can't access them? Two things, which Defender suite are these alerts coming from? Which roles/permissions are required to view them within the Defender/Unified portal?
[DevOps] dps.sentinel.azure.com no longer responds
Hello, Ive been using Repository connections in sentinel to a central DevOps for almost two years now. Today i got my first automated email on error for a webhook related to my last commit from the central repo to my Sentinel intances. Its a webhook that is automticly created in connections that are made the last year (the once from 2 years ago dont have this webhook automaticly created). The hook is found in devops -> service hooks -> webhooks "run state change" for each connected sentinel However, after todays run (which was successfull, all content deployed) this hook generates alerts. It says it cant reach: (EU in my case) eu.prod.dps.sentinel.azure.com full url: https://eu.prod.dps.sentinel.azure.com/webhooks/ado/workspaces/[REDACTED]/sourceControls/[REDACTED] So, what happened to this domain? why is it no longer responding and when was it going offline? I THINK this is the hook that sets the status under Sentinel -> Repositories in the GUI. this success status in screenshoot is from 2025/02/06, no new success has been registered in the receiving Sentinel instance. For the Sentinel that is 2 year old and dont have a hook in my DevOps that last deployment status says "Unknown" - so im fairly sure thats what the webhook is doing. So a second question would be, how can i set up a new webhook ? (it want ID and password of the "Azure Sentinel Content Deployment App" - i will never know that password....) so i cant manually add ieather (if the URL ever comes back online or if a new one exists?). please let me know.
Ingest IOC from Google Threat Intelligence into Sentinel

When I run the Logic APP, I received an HTTP error 403 "code": "ForbiddenError", "message": "You are not authorized to perform the requested operation" What's the problem ?? Regards, HA
Issue when ingesting Defender XDR table in Sentinel
Hello, We are migrating our on-premises SIEM solution to Microsoft Sentinel since we have E5 licences for all our users. The integration between Defender XDR and Sentinel convinced us to make the move. We have a limited budget for Sentinel, and we found out that the Auxiliary/Data Lake feature is sufficient for verbose log sources such as network logs. We would like to retain Defender XDR data for more than 30 days (the default retention period). We implemented the solution described in this blog post: https://jeffreyappel.nl/how-to-store-defender-xdr-data-for-years-in-sentinel-data-lake-without-expensive-ingestion-cost/ However, we are facing an issue with 2 tables: DeviceImageLoadEvents and DeviceFileCertificateInfo. The table forwarded by Defender to Sentinel are empty like this row: We created a support ticket but so far, we haven't received any solution. If anyone has experienced this issue, we would appreciate your feedback. LucasModernize security operations to secure agentic AI—Microsoft Sentinel at Ignite 2025

Sentinel Data Connector: Google Workspace (G Suite) (using Azure Functions)
I'm encountering a problem when attempting to run the GWorkspace_Report workbook in Azure Sentinel. The query is throwing this error related to the union operator: 'union' operator: Failed to resolve table expression named 'GWorkspace_ReportsAPI_gcp_CL' I've double-checked, and the GoogleWorkspaceReports connector is installed and updated to version 3.0.2. Has anyone seen this or know what might be causing the table GWorkspace_ReportsAPI_gcp_CL to be unresolved? Thanks!
Trend Micro Vision One Connector Not working
Hi All, Before I get nuked in the comments to raise an issue on the Sentinel Repo. Here me out 😇 Around a month ago, the logs stopped ingesting. A quick snoop around revealed the reason. But I'm not sure if I should raise an issue, or try to fix the issue, risking voiding any future support I can get, since the connector and the app that comes with it are market solutions. Function app was not running due to a dependency issue. Spotted this on the diagnostic logs, under the "exceptions" table. "module named _cffi_backend not found" a python package google tells me, thats used to interact with C code. So logically, I need to find the requirement.txt and make sure the dependency is there. Also make sure the python version on the runtime and Azure matches, The logs were initially flowing as usual . I had completed integrating Trend Micro using Azure Functions based connector around 7 months ago. Worked like a toyota helix until now. So once again, would like to know the community's thoughts on it. Thxx
how to connect varonis as a connector in sentinel
Hi, I would like to know the process of how can we connect Varonis as a data connector in sentinel. I understand that by reading this article Azure Sentinel: The connectors grand (CEF, Syslog, Direct, Agent, Custom and more) - Microsoft Tech Community , we can connect Varonis through CEF connector. And I have read the instructions mentioned in the article(https://info.varonis.com/hubfs/docs/splunk-app/Varonis-App-for-Splunk-User-Guide.pdf), This is what I understood, can anyone correct me if any? in Datalert configuration(in varonis), connect Syslog msg fwding by giving the Syslog server IP and port number. create an alert template with Syslog msg alert method. ***by this, varonis alerts/data will be sent to Syslog server**** 3.now, we can connect easily from the Syslog server to sentinel easily by executing a few commands which I'm aware of.
