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?

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!Data Connectors Storage Account and Function App
Several data connectors downloaded via Content Hub has ARM deployment templates which is default OOB experience. If we need to customize we could however I wanted to ask community how do you go about addressing some of the infrastructure issues where these connectors deploy storage accounts with insecure configurations like infrastructure key requirement, vnet intergration, cmk, front door etc... Storage and Function Apps. It appears default configuration basically provisions all required services to get streams going but posture configuration seems to be dismissing security standards around hardening these services.
Device Tables are not ingesting tables for an orgs workspace
Device Tables are not ingesting tables for an orgs workspace. I can confirm that all devices are enrolled and onboarded to MDE (Microsoft defender for endpoint) I had placed an EICAR file on one of the machine which bought an alert through to sentinel,however this did not invoke any of the device related tables . Workspace i am targeting Workspace from another org with tables enabled and ingesting data Microsoft Defender XDR connector shows as connected however the tables do not seem to be ingesting data; I run the following; DeviceEvents | where TimeGenerated > ago(15m) | top 20 by TimeGenerated DeviceProcessEvents | where TimeGenerated > ago(15m) | top 20 by TimeGenerated I receive no results; No results found from the specified time range Try selecting another time range Please assist As I cannot think where this is failing
