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.

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..

Post Integrating Microsoft Defender XDR with Microsoft Sentinel, does advance hunting tables reflects on log analytics tables used by Microsot Sentinel??
Top answer 1 of 2

Yeah, it will show the logs that you have enable data connectors on sentinel. So keep that in mind too when making analytics rules. For example if you have a table that is typically only on XDR advance hunting such as DeviceEvents, and you do not have the logs on Sentinel, then while you can query that table on advance hunting, it won't work as an analytic rule until you send the logs to sentinel.

Just curious - why won’t you query the XDR tables via XDR hunting? That won’t incur extra ingestion costs.
