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.
Difference between Sentinel and Defender
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).

November 14, 2024Defender for Business vs SentinelOne
It also depends which sentinelone license you are using. Downside of defender for business that you can’t use the advanced search, which sentinelone complete has. I would switch , first of all because you already pay for it, second it already has great integration with defender for Office365 etc. additional you can use the ASR rules with defender which are great, overall the additional invest for sentinelone is not worth it but you will need someone who sets up the defender for business environment properly More on reddit.com

Transition from Microsoft Sentinel to Defender XDR - Practical challenges | Hybrid Brothers
July 4, 2025 - So the first thing I did was searching for an incident that has been merged in Microsoft Sentinel (because that is the only UI where you can see a redirected incident, for the coming year at least 😉). But to request an incident via the Graph API I need the Defender XDR Incident ID (yes the Incident ID in Microsoft Sentinel is not the same ID as the Incident ID in Defender XDR), so I had to search for the Defender XDR ID using KQL.

How Does Azure Sentinel and Microsoft Defender XDR Increase Performance of Security Operations
April 13, 2021 - Now we understand XDR and Sentinel, let us replay the earlier example but this time, under the Microsoft security architecture. Due to the integrations and context sharing between the XDR products, each product enhances the fidelity of any previous alert and enriches the security incident that is generated within Azure Sentinel so that you have sight of the entire attack chain from a single view. Touching again on SOAR, using the capabilities inherent in Azure Sentinel that integrates with Defender XDR you can automate the response which is triggered in seconds and not minutes or hours.
