Multiple Subscriptions in Sentinel

Hello all,   Can I set up a central Azure Sentinel to monitor multiple subscriptions?   Or is one Azure Sentinel recommended per subscription? Best Christian

Azure Sentinel is using Log Analytics within one tenant with one to multiple subscriptions. If you have multiple subscriptions they can interact with each other with RBAC permissions of data when pulling into a sentinel workspace. If you're wanting to know how to do “cross-tenant” data monitoring you’re required to use the MSSP solution “Azure Lighthouse” with Azure Sentinel.

Is there a specific question to subscriptions that’s not clear in our documentation that we can improve upon?

Chris BoehmIs there an aggregation capability to provide a "single pane of glass" for all CSP tenants? From the documentation, it appears that the CSP can gain delegated access to each individual tenant for Log Analytics and ASC.  This https://docs.microsoft.com/en-us/azure/lighthouse/concepts/cross-tenant-management-experience mentions "cross-tenant visibility" for ASC, but does not show what the user experience is like. It would be nice to see a screen-shot showing multiple subscriptions from multiple Azure AD tenants in a centralized view in Sentinel and ASC.

    We recently announced a central incident management screen which is in private preview. You can read more about working with multiple workspaces, optionally across tenants, in our archtecture webinar (MP4, YouTube) and the (updated) presentation. You may also want to register for the MSSP and distributed organization webinar on April 20th here.

      @Ofer, I know this thread is almost a year old but I have a similar situation with multiple subscriptions but would like to use a single workspace for Sentinel. I know lighthouse is required for multi tenant but my situation is just a single tenant with multiple subscriptions and would like to use one workspace. How do I go about having this work?

        tijan2018 did you get the answer how to have multiple workspaces under single tenant added in sentinel. I couldn’t find a way to get it done, any pointers that would help?

        thanks
