Advanced threat hunting saves significant time in tracking and responding to incidents
Microsoft Defender XDR could be improved with a lower price. My main suggestion would essentially be what Copilot is providing, which is a single pane of glass, so I don't have to go to different windows. That's just a workflow consideration for me. It would be great to have all the information centralized into one particular data app. If I need to open up extra ones, I can, however, I would appreciate a future where everything I need is right there on one single pane of glass. Beyond that, there's really nothing else I see that I would want Microsoft to improve.

A scalable and stable solution with straightforward deployment
We can generate maps from the environment. For example, suppose there is a virus that has a zero-day attack and is publicly unknown. We can block that and keep it away from the network so it is not further replicated. It also has custom white and black lists. We can add a good reputation on both lists and use the sonar technology for Symantec and the online network for advanced reports.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The best feature is threat hunting. There are a lot of other features I like, such as the alert mechanism. The chain alert mechanism has a huge impact. It combines all the alerts into one incident and automatically correlates them with AI."
"We are able to consolidate licences and make use of many Microsoft products using this solution. If we have any Microsoft customers, we encourage them to use this solution for enterprise defence."
"Defender XDR enables you to scan a system remotely and get a complete inventory of its assets. You can gather more information from the asset inventory and apply threat intelligence using Office 365 or something."
"The best feature is probably the alert generation. When I do a security reset, the other session triggers instantly from the Defender console, and I can work on it. The policies are three times, but they are also ready to install it."
"One of the most valuable features of Microsoft Defender XDR is its ability to provide preemptive reports regarding excessive privileged access."
"What I like most about the product is its all-in-one solution. With Microsoft Defender XDR, we get coverage for various aspects like endpoint security, cloud security, and image-related cases, all within a single platform. This eliminates the need for multiple products or technical controls to address incidents. The main benefit became evident immediately after deployment, especially in its ability to analyze files and phishing emails quickly. By submitting suspicious files or emails, we receive quick results on whether they are legitimate, suspicious, or malicious, saving time."
"I rate Microsoft Defender XDR 10 out of 10."
"Microsoft Defender XDR has significantly improved our operational security."
"You can advise the solution and protect your environment."
 

Cons

"The advanced threat-hunting capabilities are phenomenal, and the security copilot enhances that, but some data elements could be better or have more context inside of the advanced tables themselves. The schemas feel a little limited to what they're building into the product. It's probably just a maturity thing. I imagine we'll see the features I want in the next year."
"Microsoft Defender XDR is not a full-fledged EDR or XDR."
"There are still some components, such as vulnerability management within the vendor product, where improved integration would be beneficial."
"The management and automation of the cloud apps have room for improvement."
"There's still some more work to be done there. Additionally, the limited terminal live access an analyst has is very restricted."
"The price could be better. It'll also help if they can continuously update and upgrade the solution. Every day there's a new virus uploaded into the network, and we have to keep updating it to identify all these things."
"The abundance of sub-dashboards and sub-areas within the main dashboard can be confusing, even if it all technically makes sense."
"At times, when we have an incident email and we click on the link for that incident, it opens a pop-up, but there is nothing. It has happened a couple of times."
"The solution should have better reporting."
 

Pricing and Cost Advice

"I would like to have more security features in the lower licenses because not every customer is able to buy E5 licenses. The bundling isn't always easy for our customers to understand. Compared to other tools, it's a good price."
"The functionality is fantastic, but for medium and small-sized companies it's overpriced. It would be better if it were a little bit cheaper."
"On average, we pay around 55 euros per user for the services and features we receive."
"We've managed to navigate it effectively through our enterprise agreement, and Microsoft's academic discounts have proven to be quite generous."
"There are no issues with pricing, but sometimes, the clarity in licensing is a concern."
"The licensing fee for Microsoft 365 Defender is fair."
"Microsoft is not competitive with the pricing of the solution. The competitors are able to offer lower discounts. The price of the solution is higher."
"I believe that the pricing of the licensing is fair."
