Microsoft Defender XDR Likes & Dislikes

We can find alerts from different sources like identities, devices, emails and cloud apps into single platform. This reduces the triage and investigation time. It also seamlessly integrates with Microsoft sentinel though a connectors

That it's easy to navigate to, easy to use much like our other M365/O365 products we are currently subscribed to i.e. M365 Exchange/Entra/Intune/Teams Admin Centre etc.

The biggest strength of Microsoft Defender XDR is its ability to connect activity across multiple security domains and present it as a single, coherent attack story.

As all the alerts from other products are linked sometimes there might be confusion while gathering alert evidence. If policies are not configured or finetuned properly then number of false positives might increase which will lead to unnecessary noise.

Our current subscription is basic and is only covered with the essentials that MS Defender has to offer.

There are some challenges that come with Microsoft Defender XDR. The amount of information presented during incidents can feel overwhelming, particularly for teams that are new to extended detection and response platforms.
