Introduction If you have connected your Microsoft Sentinel instance to your Microsoft Defender instance (and if not, why not?), you know that the same incidents and alerts will show up in both instances. You can use either the Microsoft Sentinel REST API or the MS Graph to get the data. So, which one should it […]
Introduction In my last post, I talked about how to get a single (or a few) entries from a Microsoft Sentinel watchlist. I introduced the fact that watchlists are stored in the “Watchlist” table. We can use this to perform cross workspace queries. _GetWatchlist Again, in my last blog post, I talked about the “_GetWatchlist” […]
Introduction UPDATE: Modified the code to show Required Data Connectors information and the workbook to use this information. With Microsoft Sentinel moving everything into the Content Hub it may be hard to find the solution you need. You can currently search in the Content Hub, but it will only search the Title and description for […]

Introduction I recently had someone tell me that code I had written a while ago to allow the user to automatically update rules from rule templates didn’t get all the rule templates. After mumbling some comments under my breath that I should not mention here, I decided to take a look. First of all, I […]
Introduction I am sure a lot of you, like me, miss being able to call sub-routines in KQL. You can always create a function and call that, but it isn’t quite the same thing. This is where mv-apply comes into play. The official documentation for mv-apply (located here) states that it “Applies a subquery to […]
Introduction This post is in response to a question that was asked on LinkedIn. The person wanted to know how to get the custom hunting queries using the REST API since it didn’t seem that any of the Microsoft Sentinel APIs retrieve that information. That is correct.
