Dedicated cluster for Sentinels in different tenants
Hello I see that there is a possibility to use a dedicated cluster for a workspace in the same Azure region. What about workspaces that reside in different tenants but are in the same Azure region? Is that possible? We are utilizing multiple tenants, and we want to keep this operational model. However, there is a central SOC, and we wonder if there is a possibility to utilize a dedicated cluster for cost optimization.Issue connecting Azure Sentinel GitHub app to Sentinel Instance when IP allow list is enabled
Hi everyone, I’m running into an issue connecting the Azure Sentinel GitHub app to my Sentinel workspace in order to create our CI/CD pipelines for our detection rules, and I’m hoping someone can point me in the right direction. Symptoms: When configuring the GitHub connection in Sentinel, the repository dropdown does not populate. There are no explicit errors, but the connection clearly isn’t completing. If I disable my organization’s IP allow list, everything works as expected and the repos appear immediately. I’ve seen that some GitHub Apps automatically add the IP ranges they require to an organization’s allow list. However, from what I can tell, the Azure Sentinel GitHub app does not seem to have this capability, and requires manual allow listing instead. What I’ve tried / researched: Reviewed Microsoft documentation for Sentinel ↔ GitHub integrations Looked through Azure IP range and Service Tag documentation I’ve seen recommendations to allow list the IP ranges published at //api.github.com/meta, as many GitHub apps rely on these ranges I’ve already tried allow listing multiple ranges from the GitHub meta endpoint, but the issue persists My questions: Does anyone know which IP ranges are used by the Azure Sentinel GitHub app specifically? Is there an official or recommended approach for using this integration in environments with strict IP allow lists? Has anyone successfully configured this integration without fully disabling IP restrictions? Any insight, references, or firsthand experience would be greatly appreciated. Thanks in advance!Webinar Rescheduled: AI-Powered Entity Analysis in Sentinel's MCP Server

Register for Microsoft Ignite >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.
Single Rule for No logs receiving (Global + Per-device Thresholds)
Hi everyone, I currently maintain one Analytics rule per table to detect when logs stop coming in. Some tables receive data from multiple sources, each with a different expected interval (for example, some sources send every 10 minutes, others every 30 minutes). In other SIEM platforms there’s usually: A global threshold (e.g., 60 minutes) for all sources. Optional per-device/per-table thresholds that override the global value. Is there a recommended way to implement one global rule that uses a default threshold but allows per-source overrides when a particular device or log table has a different expected frequency? Also, if there are other approaches you use to manage “logs not received” detection, I’d love to hear your suggestions as well. This is a sample of my current rule let threshold = 1h; AzureActivity | summarize LastHeartBeat = max(TimeGenerated) | where LastHeartBeat < ago(threshold)
