Microsoft Defender XDR has improved our overall security visibility and helped reduce the time required to detect and respond to threats across endpoints, identities, email, and cloud workloads.

Based on what I've seen with Microsoft Defender XDR and the large amount of threat data Microsoft has access to, I'm confident I would trust Microsoft Security to handle the majority of all our threats from any threat actor who's essentially putting our company at risk.

As a reseller and partner, the advantages of Microsoft Defender XDR are numerous; I have stopped many threats for many organizations using Defender alone, and I have saved significant IT management time by avoiding manual updates and manual work.

What I appreciate most about Microsoft Defender XDR is the ability to drill down to the process level, the visibility of processes, and the file-level details of what processes are accessing, including the IP addresses for outbound connections.

The proactive remediation aspects and the surfacing of suspicious activity for investigation and escalation are the key aspects we appreciate most.

The feature I like the most in Microsoft Defender XDR is XDR because it has taken us a while, but we are a global company with people in a few countries, and now we can have centralized alerts that we send out to Teams messages and clean up infected computers or help people in a very short amount of time.

What I appreciate most about Microsoft Defender XDR is the visibility it provides through a breakdown of incidents that come through.

Microsoft Defender XDR is very comprehensive, covering a lot of the services, tools, and applications that we use, so it's very efficient, and it works out of the box.

The feature of Microsoft Defender XDR that I preferred the most traditionally was its focus on endpoint protection, but now identity is right up there with endpoint security. Identity is important because different compromises start at the identity level. This allows us to understand what actions are being taken, who is doing them, and whether it is actually them.

The automation response being slow is the main concern; when an incident occurs or if I run a remediation, it takes significant time to complete the remediation.

From my perspective, Microsoft Defender XDR can be improved with better visibility in certain areas where I can trigger host isolation on one machine.

Every now and then, Microsoft Defender XDR seems to go through and aggregates almost a week's worth of incidents and wraps them up, indicating a huge problem.

I haven't really come across the incident Q assistant helping improve the efficiency of my SOC workflow.

Microsoft Defender XDR can be improved as a solution because it's still quite costly; it's part of E5, E5 security, so the cost is still quite high, especially considering SME and C customers, or SMB customers.

The customer support aspect can be better because it's the biggest complaint I hear about Microsoft. They can improve the ease of support and licensing processes.
