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…

The solution's graphing is highly specific and useful
Implementing policies in the solution isn't easy, and it takes time. For example, you need to use some secrets in Windows or Mac to execute your policies, and you can assign these policies with Microsoft Intune. However, when you execute a policy, you still need to wait up to two days to see alerts. Some of our customers aren't happy because they didn't expect it to take so long. They're satisfied once it starts working because they see the alerts and graphs. The user interface also isn't user-friendly. When we introduce Insider Risk Management to our clients, they often find it difficult to understand. There is too much information, and the UI is not scalable. Also, entry-level IT technicians are not always interested in learning something new. It should be clearer and easier to understand. Microsoft is still working on machine learning and AI components. They're constantly updating the product. However, from my experience, most of my customers are not ready or able to use the AI solution. They are creating some project plans and specific policies. They don't want to see dozens of alerts when they use Microsoft's recommendations or the AI-based solution.

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."
"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 Purview Insider Risk Management was helpful in performing investigations after alerts were received."
"Insider Risk Management's graphing is highly specific and useful. You can see the last six months of data for the Microsoft tenant. You can easily find what you need. For example, you can filter for alerts about devices, emails, etc."
"The best thing about Purview is that it's easy to integrate with our day-to-day environment. We have Active Directory, and Word and Excel. Using a third-party vendor and trying to integrate with our existing environment would be much more challenging."
 

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."
"The reporting capabilities sometimes leave a little to be desired. It could be improved in terms of producing reports to provide information to the C-suite or others."
"For certain things, you need to install an agent. I understand it's for integrity, but if there could be a clientless solution for certain aspects, it would make life easier."
"The user interface also isn't user-friendly. When we introduce Insider Risk Management to our clients, they often find it difficult to understand. There is too much information, and the UI is not scalable. Also, entry-level IT technicians are not always interested in learning something new. It should be clearer and easier to understand."
