Can anyone explain why the Office Activity table does show up in Microsoft Defender advanced hunting yet you can see it in Sentinel. I'm circling back to this after a couple of years out of the game and could have sworn you used to get that table in Defender.... I'm getting old so maybe it's that....

Without going to deep on this : Sentinel is a siem/soar solution and far more than ‘just’ the defender platform. Giving you the possibility to create custom usecases, automated response etc. Over far more datasources. Defender (xdr) is the collection of (endpoint) protection solutions created by microsoft in order to protect their modern workplace solution (windows, m365, cloud apps and certain azure resources).

OfficeActivity is the name of the Sentinel table that contains a subset of the SPO/EXO/Teams logs. Its not 1:1 with the UAL for some stupid reason..

r/DefenderATP on Reddit: Is Sentinel necessary for Defender XDR
November 14, 2024 -
We have an audit running at the moment, and the technician is telling me that Sentinel is necessary for Defender XDR.
My opinion is, that XDR is a SIEMless system, hence no need for a SIEM but similar performance. But Sentinel is a SIEM, so that would defeat the idea of XDR.
Does anyone know if Sentinel is actually necessary for the XDR Detections or if it is just to have "better" automation?

Sentinel is more than just a SIEM aka place to store logs. It is a SOAR as well. Going back to your question, no it's not needed and you can go with just Microsoft XDR but you are missing lots of functionality Threat Intelligence Custom analytic rules Playbooks aka logic apps Etc I would never recommend XDR without Sentinel though, unless you have a very tight budget of course.

SIEM in no way ”defeats the idea of XDR”. Most large orgs run both. Do you need to do custom data sources / integrations? Response automation? If so you need Sentinel OR some other SIEM/SOAR.

November 16, 2020 - Therefore, if you configure some of the Defender products such as Microsoft Cloud App Security, Defender for Endpoint and so on, then you can surface that information in your multi-tenant portal, in Azure Lighthouse/Sentinel. So that is the reason that you will most likely want to consider both very carefully, if you are building a Managed Security Practice (they are certainly better taken together). That having been said, if you are brand new to all of these products, I would recommend that you “dig in” starting with the Defender XDR stuff, and moving over to Azure Sentinel after that:

October 13, 2020 - In my opinion that makes it crystal clear that on the one side, Microsoft is merging and aligning the tools in Microsoft 365 Defender (formally known as "Microsoft Threat Protection").

Nadella's statement - on the other side, was important for customers to see that Microsoft is investing in both areas, SIEM & XDR, and sees both products, Azure Sentinel & Microsoft 365 Defender, side-by-side.
