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.

I also like the ability to remotely manage update packages on your systems, and the fact that there is an open source version
Setting OpenEDR was challenging at first, but I got it done by following their documentation and online videos. You need to install the client and configure it to work with their online open platform. Next, you have to configure it on the device if it's a phone. You input a cloud link to the EDR, so you can monitor it from the cloud. There isn't any maintenance aside from updating the client. It's mostly on the cloud.

Quotes from Members

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

Pros

"Defender XDR has a feature called the timeline that lets you track all activities. It helps a lot with investigations."
"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."
"All of the security components are valuable including, antiphishing, antispam, and stage three antivirus."
"For technical support, I would definitely give a rating of nine out of ten."
"It gives a lot of flexibility in terms of configuration and customization as per the business requirements."
"The Email Explorer feature has proven invaluable, offering a broader perspective than automated alerts and incidents alone."
"My clients like Defender's file integrity monitoring. They're monitoring Windows and Linux system files."
"It has been great for us. Previously, we didn't have a solution to protect us, especially from malware, whereas now, we are getting protection up front, especially from the malware attacks coming through emails or endpoints."
"Comodo includes a firewall and antivirus in one solution. I also like the ability to remotely manage update packages on your systems. Comodo can even find a lost device and secure it remotely."
 

Cons

"The support could be more knowledgable to improve their offering."
"I personally have not seen much evidence of how Defender can enhance the story of zero trust for enterprises."
"At times, there may be delays in the execution of certain actions and their effects."
"Some of our older hardware experienced a slight bump in CPU and memory usage. Although I don't have empirical data to back that up, I would suggest possibly more streamlining in the software."
"Microsoft 365 Defender does not have a unique package with emerging endpoint security technologies, such as EDR and XDR."
"The price should be adjustable by region."
"Microsoft Defender XDR could be improved with a lower price."
"While the XDR platform offers valuable functionalities, it falls short of other solutions in its ability to deliver a cohesive identity experience."
"Comodo includes a firewall and antivirus in one solution. I also like the ability to remotely manage update packages on your systems. Comodo can even find a lost device and secure it remotely."
 

Pricing and Cost Advice

"365 Defender can get expensive because you pay per gigabyte of data ingested. On the other hand, much of the data available in the other Microsoft security solutions are made available relatively cheaply—sometimes at cost or for free. Integrating only a limited set of third-party solutions with Sentinel would be cost-effective. It's much more affordable if companies only have Microsoft stuff."
"I find the pricing to be quite competitive, especially considering its inclusion in our E5 subscription, which provides a comprehensive set of functionalities."
"Its licensing and pricing are handled by someone else. My role is limited to incidents or issues with the portal, but you get what you pay for. It is worth the cost."
"While Microsoft Defender XDR carries a higher cost, its ease of use compared to Defender may justify the investment."
"The licensing fee for Microsoft 365 Defender is fair."
"Microsoft purposely makes its license combinations complex and includes combinations like Microsoft 365 E3 and Microsoft 365 E5, Office 365 E3, Office 365 E5, and Office 365 E1, so you get confused. Microsoft tries to sell you a bundle of a lot of things together."
"We've managed to navigate it effectively through our enterprise agreement, and Microsoft's academic discounts have proven to be quite generous."
"It has consistently offered highly appealing academic pricing, with distinct rates for higher education and general educational purposes."
