Sentinel RBAC in the Unified portal: who has activated Unified RBAC, and how did it go?
Following the RSAC 2026 announcements last month, I have been working through the full permission picture for the Unified portal and wanted to open a discussion here given how much has shifted in a short period. A quick framing of where things stand. The baseline is still that Azure RBAC carries across for Sentinel SIEM access when you onboard, no changes required. But there are now two significant additions in public preview: Unified RBAC for Sentinel SIEM itself (extending the Defender Unified RBAC model to cover Sentinel directly), and a new Defender-native GDAP model for non-CSP organisations managing delegated access across tenants. The GDAP piece in particular is worth discussing carefully, because I want to be precise about what has and has not changed. The existing limitation from Microsoft's onboarding documentation, that GDAP with Azure Lighthouse is not supported for Sentinel data in the Defender portal, has not changed. What is new is a separate, Defender-portal-native GDAP mechanism announced at RSAC, which is a different thing. These are not the same capability. If you were using Entra B2B as the interim path based on earlier guidance, that guidance was correct and that path remains the generally available option today. A few things I would genuinely like to hear from practitioners: For those who have activated Unified RBAC for a Sentinel workspace in the Defender portal: what did the migration from Azure RBAC roles look like in practice? Did the import function bring roles across cleanly, or did you find gaps particularly around custom roles? For environments using Playbook Operator, Automation Contributor, or Workbook Contributor role assignments: how are you handling the fact those three roles are not yet in Unified RBAC and still require Azure portal management? Is the dual-management posture creating operational friction? For MSSPs evaluating the new Defender-native GDAP model against their existing Entra B2B setup: what factors are driving the decision either way at your scale? Writing this up as Part 3 of the migration series and the community experience here is directly useful for making sure the practitioner angle is grounded.
How do I import Purview Unified Audit Log data related to the use of the Audit Log into Sentinel?
Dear Community, I would like to implement the following scenario on an environment with Microsoft 365 E5 licenses: Scenario: I want to import audit activities into an Azure Log Analytics workspace linked to Sentinel to generate alerts/incidents as soon as a search is performed in the Microsoft 365 Purview Unified Audit Log (primarily for IRM purposes). Challenge: Neither the "Microsoft 365" connector, nor the "Defender XDR" or "Purview" (which appear to be exclusively Azure Purview) connectors are importing the necessary data. Question: Which connector do I have to use in order to obtain Purview Unified Audit Log activities about the use of the Purview Unified Audit Log so that I can identify... ...which user conducted when an audit log search and with what kind of search query.

Update content package Metadata
Hello Sentinel community and Microsoft. Ive been working on a script where i use this command: https://learn.microsoft.com/en-us/rest/api/securityinsights/content-package/install?view=rest-securityinsights-2024-09-01&tabs=HTTP Ive managed to successfully create everything from retrieving whats installed, uninstalling, reinstalling and lastly updating (updating needed to be "list, delete, install" however :'), there was no flag for "update available"). However, now to my issue. As this work like a charm through powershell, the metadata and hyperlinking is not being deployed - at all. So i have my 40 content packages successfully installed through the REST-api, but then i have to visit the content hub in sentinel in the GUI, filter for "installed" and mark them all, then press "install". When i do this the metadata and hyperlinking is created. (Its most noticeable that the analytic rules for the content hubs are not available under analytic rules -> Rule templates after installing through the rest api). But once you press install button in the GUI, they appear. So i looked in to the request that is made when pressing the button. It uses another API version, fine, i can add that to my script. But it also uses 2 variables that are not documented and encrypted-data. they are called c and t: Im also located in EU and it makes a request to SentinelUS. im OK with that, also as mentioned, another API version (2020-06-01) while the REST APi to install content packages above has 2024-09-01. NP. But i can not simulate this last request as the variables are encrypted and not available through the install rest api. They are also not possible to simulate. it ONLY works in the GUI when pressing install. Lastly i get another API version back when it successfully ran through install in GUI, so in total its 3 api versions. Here is my code snippet i tried (it is basically a mimic of the post request in the network tab of the browser then pressing "install" on the package in content hub, after i successfully installed it through the official rest api). function Refresh-WorkspaceMetadata { param ( [Parameter(Mandatory = $true)] [string]$SubscriptionId, [Parameter(Mandatory = $true)] [string]$ResourceGroup, [Parameter(Mandatory = $true)] [string]$WorkspaceName, [Parameter(Mandatory = $true)] [string]$AccessToken ) # Use the API version from the portal sample $apiVeri = "?api-version=" $RefreshapiVersion = "2020-06-01" # Build the batch endpoint URL with the query string on the batch URI $batchUri = "https://management.azure.com/\$batch$apiVeri$RefreshapiVersion" # Construct a relative URL for the workspace resource. # Append dummy t and c parameters to mimic the portal's request. $workspaceUrl = "/subscriptions/$SubscriptionId/resourceGroups/$ResourceGroup/providers/Microsoft.OperationalInsights/workspaces/$WorkspaceName$apiVeri$RefreshapiVersion&t=123456789&c=dummy" # Create a batch payload with several GET requests $requests = @() for ($i = 0; $i -lt 5; $i++) { $requests += @{ httpMethod = "GET" name = [guid]::NewGuid().ToString() requestHeaderDetails = @{ commandName = "Microsoft_Azure_SentinelUS.ContenthubWorkspaceClient/get" } url = $workspaceUrl } } $body = @{ requests = $requests } | ConvertTo-Json -Depth 5 try { $response = Invoke-RestMethod -Uri $batchUri -Method Post -Headers @{ "Authorization" = "Bearer $AccessToken" "Content-Type" = "application/json" } -Body $body Write-Host "[+] Workspace metadata refresh triggered successfully." -ForegroundColor Green } catch { Write-Host "[!] Failed to trigger workspace metadata refresh. Error: $_" -ForegroundColor Red } } Refresh-WorkspaceMetadata -SubscriptionId $subscriptionId -ResourceGroup $resourceGroup -WorkspaceName $workspaceName -AccessToken $accessToken (note: i have variables higher up in my script for subscriptionid, resourcegroup, workspacename and token etc). Ive tried with and without mimicing the T and C variable. none works. So for me, currently, installing content hub packages for sentinel is always: Install through script to get all 40 packages Visit webpage, filter for 'Installed', mark them and press 'Install' You now have all metadata and hyperlinking available to you in your Sentinel (such as hunting rules, analytic rules, workbooks, playbooks -templates). Anyone else manage to get around this or is it "GUI" gated ? Greatly appreciated.[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.
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. ThxxIssue while deploying Sentienl Rules
I know that when deleting a Sentinel rule, you need to wait a specific amount of time before it can be redeployed. However, in this tenant, we've been waiting for almost a month and are still getting the same deployment error ('was recently deleted. You need to allow some time before re-using the same ID. Please try again later. Click here for details'). I still want to use the same ID ect. Does anyone have any idea or similar issue why it's still not possible after waiting for about a month?
