Helps detect threats faster and prioritize critical security tasks with increased visibility
The feature I value most about Microsoft Defender for Identity is the ability to see where people are attempting to log in from. Microsoft Defender for Identity helps me automate routine tasks and find alerts that I set up to receive, so it helps me get where I'm trying to go easier and faster. I can see where everything is at. Microsoft Defender for Identity helps me prioritize important tasks. If I get an alert for a user who downloaded an application that is not sanctioned, I normally go straight to that user's computer device to find the device name and the user. Now I can get to them much faster. Microsoft Defender for Identity saves me time overall. I can quantify the time saved by Microsoft Defender for Identity as maybe 25 minutes, or if expressed as a percentage, maybe 20 to 25%. Some of the learning curve and actually learning what these products do takes time to figure out. Microsoft Defender for Identity definitely helps decrease the time of detection and response.

Automated security monitoring increases efficiency, but market visibility needs improvement
I am currently evaluating Stellar Cyber Open XDR in terms of their support. I do not see any major areas for improvement as of now. Their support is good, and the team is small, enabling them to cater to everyone effectively. While I have not encountered significant drawbacks so far, market penetration is challenging due to the product's newness, despite its flexibility and customization features. I find their user interface to be quite good.

Quotes from Members

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

Pros

"It automates routine testing and helps automate the finding of high-value alerts."
"The advanced threat protection is one of the strengths of Microsoft Defender for Identity, as it utilizes user and entity analytics and can detect indicative attacks."
"Auto-remediation is a valuable feature applied to Microsoft Defender for Identity, reducing the burden of investigating false positives."
"We do not see any issues with the stability of Microsoft Defender for Identity. I can say it is 100% stable."
"This solution has advanced a lot over the last few years."
"The most valuable aspect is its connection to Microsoft Sentinel and Defender for Endpoint, and giving exact timelines for incidents and when certain events occured during an incident."
"I would rate Microsoft Defender for Identity at nine out of ten."
"It gives you a holistic view of everything happening in your organization, and you can use it to do a lot of monitoring."
"It can integrate with almost any cybersecurity tool available in the market."
"Stellar Cyber Open XDR offers these functionalities at a more affordable price, making it easier for me to position it with price-sensitive customers."
 

Cons

"I would like to be able to do remediation from the platform because it is just a scanner right now. If you onboard a device, it shows you what is happening, but you can't use it to fix things. You need to go into the system to fix it instead."
"Microsoft should look at what competing vendors like CrowdStrike and Broadcom are doing and incorporate those features into Sentinel and Defender. At the same time, I think the intelligence inside the product is improving fast. They should incorporate more zero-trust and hybrid trust approaches. They need to build up threat intelligence based on threats and methods used in attacks on other companies."
"The technical support needs significant improvement. Documentation for more minor issues in the form of guides or walkthroughs could help to resolve this issue. The number of tickets raised would decrease, removing some pressure from the support team and making it easier to clear the remaining tickets."
"One area that needs improvement is the number of alerts generated, leading to alert fatigue."
"Defender for Identity gives us visibility, but we often get false positives from Azure that take us down the garden path. We go through 30 incidents each day and most of those are false positives or benign positive alerts. Occasionally, we get true positive alerts."
"Fixing the solution isn't very seamless."
"One improvement I would recommend is the integration of an admin application within Teams, allowing easy access to attack information on a mobile platform to promptly alert affected users and their friends."
"The impact of the sensors on the domain controllers can be quite high depending on your loads. I don't know if there's any room for improvement there, but that's one of the things that might be improved."
"I would rate the stability at about five to six. The platform requires some fine-tuning, especially when integrating data sources and creating connectors."
"Support is an issue because they have a limited number of resources."
 

Pricing and Cost Advice

"Defender for Identity is a little more expensive than other Microsoft products. Identity and Microsoft Defender for Cloud are both a bit costly."
"The product is costly, and we had multiple discussions with accounting to receive a discounted rate. However, on the open market, the tool is expensive."
"You won't be able to change your tenants from where you deploy them. For example, if you select Canada, they will charge you based on Canadian pricing. If you are also in London, when you deploy in Canada, the pound is higher than Canadian dollars, but your platform resources are billable in Canadian dollars. Using your pounds to pay for any of these things will be cheaper. Or, if you deploy in London, they will charge you based on your local currency."
"Microsoft Defender for Identity comes as part of the Microsoft E5 licensing stack."
"It is very affordable considering that other SIEM solutions are much more expensive and have many more licensing restrictions and fees."
"It’s a single license platform."
