Enhanced visibility and exposes vulnerabilities but needs more integration
I am currently in the pilot stage of implementing Microsoft External Attack Surface Management (EASM). My organization is transitioning to a comprehensive track of Microsoft solutions, and we will move to full-scale production in another year, maybe Microsoft External Attack Surface Management…
ROBERT-CHRISTIAN - PeerSpot reviewer
Integration within the ecosystem enhances collaboration and automates functionalities
The integration into the Microsoft Defender ecosystem is the most valuable feature of Microsoft Defender for Identity. It fits very nicely with all the other Defender tools, allowing for excellent collaboration among them. It also fits seamlessly into Microsoft Sentinel SIEM. Furthermore, Microsoft security solutions can save time as they allow the automation of numerous functionalities, and the reporting inside the Microsoft ecosystem is commendable.

Quotes from Members

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

Pros

"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"It seems to be better at protecting from cyberattacks."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"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."
"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."
"Auto-remediation is a valuable feature applied to Microsoft Defender for Identity, reducing the burden of investigating false positives."
"The solution’s alerting is fairly efficient."
"All the integration it has with different Microsoft packages, like Teams and Office, is good."
"Microsoft Defender for Identity provides excellent visibility into threats by leveraging real-time analytics and data intelligence."
"The feature I like the most about Defender for Identity is the entity tags. They give you the ability to identify sensitive accounts, devices, and groups. You also have honeytoken entities, which are devices that are identified as "bait" for fraudulent actors."
"I recommend Microsoft Defender for Identity because it is easy to implement."
 

Cons

"With Microsoft, support is always crazy, it's not easy to get support."
"Further integration across different Microsoft products would be an improvement."
"The integration is not as seamless compared to competitors like Palo Alto."
"When the data leaves the cloud, there are security issues."
"Feedback on sync issues with the Microsoft portal highlighted its slow nature, with syncs sometimes taking eight hours."
"One potential area for improvement could be exploring flexibility in the installation of Microsoft Defender for Identity agents."
"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 solution could be better at using group-managed access and they could replace it with broad-based access controls."
"The documentation provided by Microsoft is often seen as a waste of time."
"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."
"The tracking instance needs to be configured appropriately."
 

Pricing and Cost Advice

Information not available
"It is very affordable considering that other SIEM solutions are much more expensive and have many more licensing restrictions and fees."
"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."
"Defender for Identity is a little more expensive than other Microsoft products. Identity and Microsoft Defender for Cloud are both a bit costly."
