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.

"IBM Watson for Cyber Security is very stable."
"From what I have seen so far, this is an excellent product."
"Microsoft Defender XDR is scalable."
"Microsoft 365 Defender is simple to upgrade."
"Instead of an hour, it takes five or 10 minutes now; it's a lifesaver for me and keeps my clients from being threatened and attacked every day."
"The biggest return on investment when using Microsoft Defender XDR for me is saving time for the most part."
"It provides a single pane of glass within the 365 admin interface, streamlining our experience by consolidating information in one place and eliminating the need to navigate through multiple interfaces."
"The most valuable aspect is undoubtedly the exploration capability"

Cons

"In the future, I would like to see threat intelligence included."
"The dashboard could improve in IBM Watson for Cyber Security."
"In the future, I would like to see threat intelligence included."
"This is an expensive product, so making it more cost-effective would be an improvement."
"The dashboard could improve in IBM Watson for Cyber Security."
"This is an expensive product, so making it more cost-effective would be an improvement."
"They need to continue to build the AI capabilities."
"They need to continue to build the AI capabilities."
"The technical support from Microsoft Defender XDR has been disappointingly slow, to the point that I am considering not renewing my unified support contract."
"Generally, antivirus products provide a central control to manage every device in terms of who is installing it or who is trying to disable it, but Microsoft doesn't have such a control center for the antivirus product it provides."
"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."
"The initial time spent setting up and configuring Defender XDR is a bit longer than the other solutions. If everything were on one portal, the platforms for managing policies or alerts would be simpler. We must automate and manage policies on Intune rather than the same portal."
"The dashboards could be improved."
"The solution does not offer a unified response and standard data."
"One of the biggest downsides of Microsoft products, in general, is that the menus are often difficult to find, as they tend to move from place to place between versions."
"My client would like the solution to be more customizable without using code. You can only build on the default console, but we're not allowed to change it."

Pricing and Cost Advice

"The price of this solution should be lower, although I understand why IBM charges a premium price."
"IBM Watson for Cyber Security is very simple to license and is priced well."
"On average, we pay around 55 euros per user for the services and features we receive."
"All I can say again is the E5 gives you all the capabilities that it offers. It also gives Office 365 and one terabyte of storage. All in all, the E5 license model makes sense. There are some people who say it's quite costly, but rather than paying different vendors, it makes sense to go all in with Microsoft if you've got that licensing. From that perspective, it's cost-effective, but I can't comment much on that."
"The solution is too expensive."
"I believe that the pricing of the licensing is fair."
"Defender XDR is included in the E5 license, but it's a bit too expensive."
"We've managed to navigate it effectively through our enterprise agreement, and Microsoft's academic discounts have proven to be quite generous."
"Understanding the subscription model has been a bit challenging, as every feature or requirement comes with an additional cost."
"For Defender, they have Endpoint Plan 1 and Endpoint Plan 2, but I don't know on what basis they have classified Endpoint Plan 1 and Plan 2, but it has given me enough pain to pick and design Endpoint Plan 1 or Endpoint Plan 2 for my organization. In fact, we are still struggling with it. Too many SKUs are confusing. There should not be too many SKUs, and they shouldn't charge for every new feature."
