Protect on-premises and hybrid environments with advanced threat detection and seamless integration
Our Active Directory implementation is a hybrid one. 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. It identifies lateral movements, privilege escalations, and alerts on potential attacks. The tool is also used for security posture assessment. The seamless integration with other Microsoft solutions within our Microsoft-centric environment is also a major advantage.

Facilitates compliance and records management but needs user-friendly enhancements
The features I appreciate the most in Microsoft Purview Communication Compliance include the ability to build cases, give them dates, and find them based on the notes that I left behind. The importance of Microsoft Purview Communication Compliance building taking into account critical regulations from around the world is very significant. It helps us stay up to date. While I don't need the functionality, Purview delivers data protection across multi-cloud and security platform environments, including AWS and GCP. It takes into account critical regulations from around the world. It helps us stay up to date with what's going on. We can show compliance in real-time. It's very easy to pull records. The time it saves is very useful.

Quotes from Members

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

Pros

"I recommend Microsoft Defender for Identity because it is easy to implement."
"The solution’s alerting is fairly efficient."
"The most valuable features of Microsoft Defender for Identity include real-time information for threat detection, its inclusion of behavioral analytics, and vulnerability management."
"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."
"Microsoft Defender for Identity provides excellent visibility into threats by leveraging real-time analytics and data intelligence."
"It is easy to set up. Based on the number of devices you would like to set up, you can use scripts, Group Policy, etc. It takes five minutes to set up."
"In the security portfolio that we manage, Microsoft Defender for Identity is very important because it is the professional service that we sell the most."
"The solution offers excellent visibility into threats."
"Customer support is excellent."
"The features I appreciate the most in Microsoft Purview Communication Compliance include the ability to build cases, give them dates, and find them based on the notes that I left behind."
"The time it saves is very useful."
"Microsoft Purview Communication Compliance helps with extra collaboration and ensures communication is within the framework."
 

Cons

"The solution should provide more detailed data regarding anomaly detections."
"The areas of Microsoft Defender for Identity that can be improved include its cost, which is quite expensive when integrated into Sentinel. Additionally, there is room for improvement in its integration with non-Microsoft applications and systems."
"One potential area for improvement could be exploring flexibility in the installation of Microsoft Defender for Identity agents."
"I can't say that I've seen a return on investment since we have Microsoft Defender for Identity because we also have another security solution in place."
"We observe a lot of false positives. Sometimes, when we go for a coffee break, we lock our screens. Locking the screen has a separate Windows event ID and sometimes I see it is detected as a failed login."
"The solution could improve how it handles on-premises Android-related attacks."
"Fixing the solution isn't very seamless."
"They should improve the automation for impossible travel detection. When connected to Wi-Fi and then to VPN, the system sometimes interprets the IP address change as impossible travel."
"The product should incorporate more automation with the help of AI."
"Microsoft Purview Communication Compliance can be improved by having more tutorials available for those who aren't used to using this platform."
"Microsoft Purview Communication Compliance can be improved by having more tutorials available for those who aren't used to using this platform."
"Monitoring and compliance for web applications could be improved."
 

Pricing and Cost Advice

"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."
"It is very affordable considering that other SIEM solutions are much more expensive and have many more licensing restrictions and fees."
"Defender for Identity is a little more expensive than other Microsoft products. Identity and Microsoft Defender for Cloud are both a bit costly."
"Microsoft Defender for Identity comes as part of the Microsoft E5 licensing stack."
"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."
