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…

Cloud Security Engineer at a computer software company with 51-200 employees
Has helped with regional threat monitoring but needs better documentation and real-time capabilities
The documentation from Microsoft needs significant improvement. The documents are disorganized, with one document linking to another, making the steps unclear and difficult to follow. Regarding updates, it is not truly real-time as it takes between eight to twelve hours for updates to occur. It would be beneficial if updates could happen more quickly, perhaps within 10 minutes to half an hour. Support for integration and documentation needs to be more straightforward. The pricing is expensive, even though it is part of the E5 package.

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."
"The product's stability is very high...The scalability of the product is amazing."
"The most valuable aspect is the kind of assessment results I get, and the recommendations provided in Microsoft products really help in taking care of the resources."
"The main advantage of Microsoft Defender Vulnerability Management is that it can locate and prevent most threats even when the endpoints are not connected to the corporate network, as long as the internet is available."
"The recommendations, scores, and steps to remediate actions are highly useful."
"The solution is up-to-date and helps prevent zero-day attacks."
"Microsoft Defender Vulnerability Management has streamlined our threat management processes and provided region-specific customization for our healthcare operations."
"Microsoft Defender Vulnerability Management provides several valuable features that I utilize, as I use it to control security configuration, for example, the apps that I use or the many connections from my router, and with this configuration, I can filter content and malware."
"The solution helps identify threats and vulnerabilities."
 

Cons

"The integration is not as seamless compared to competitors like Palo Alto."
"Further integration across different Microsoft products would be an improvement."
"With Microsoft, support is always crazy, it's not easy to get support."
"Integration can be improved."
"The worst aspect is the refresh rate of the dashboard. A vulnerability I patch within 15 minutes takes 24 additional hours for an update."
"We have experienced some logging issues, including a few hours of downtime initially. Despite this, I would rate the overall stability as an eight."
"There is a good solution from Microsoft, however, there is a gap between Windows and Linux management."
"It is expensive."
"The product is not stable; it is very resource-intensive, consuming a lot of memory and CPU, which makes it slow."
"There should be risk scoring added to Microsoft Defender Vulnerability Management; specifically, they call it quantification of the risk."
"Regarding Microsoft's technical support, I would rate it a three out of ten; they could be more responsive and knowledgeable."
