When connecting Microsoft Sentinel to Defender XDR, there are a couple of changes happening in tables which you should be aware of. Even though they are documented in the Microsoft Learn, I it is not always clear what the exact impact is. Let's go over it together.

Microsoft announced on the 1st of July 2025 that the Microsoft Sentinel Azure Portal UI will be deprecated at the 1st of July 2026, and all requests will be redirected to the Security Portal instead. This means that all Microsoft Sentinel customers have 1 year time to transition to the Unified experience between Microsoft Sentinel and Defender XDR.
