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…
Ankit Gupta. - PeerSpot reviewer
Comprehensive identity management enhances security and access controls with advanced integration
The monitoring from Microsoft Entra ID Protection provides great visibility at a granular level. It provides all the details, including IP address, username, and permission or error logs. This information is available in both the audit log and regular log. The alert functionality supports general day-to-day monitoring and any violation or trigger for errors. Microsoft Entra ID Protection's features are suitable for all sizes of companies. It's a must-have product because traditionally Active Directory was used for identity and authentication on computers. Now, with hybrid capabilities, every company of any size needs these features and tools. I rate Microsoft Entra ID Protection ten out of ten.

Quotes from Members

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

Pros

"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."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"For me, automatization is most valuable."
"I find the most valuable feature to be conditional access. It allows for comprehensive security controls, network security, and application label security."
"I use conditional access most of the time."
"The most valuable features are the API apps, which I use to connect to my cloud Protection."
"The tool is simple and you can find a lot of tutorials, and videos on YouTube that can help you."
"The multifactor authentication feature is effective, providing an additional layer of security."
"The valuable features of Entra ID Protection include providing me visibility of my entire estate, managing access, and having a level of control."
"The reverse proxy feature provides additional security that is not available in other solutions."
 

Cons

"Further integration across different Microsoft products would be an improvement."
"With Microsoft, support is always crazy, it's not easy to get support."
"The integration is not as seamless compared to competitors like Palo Alto."
"Support or customer service with Microsoft Entra ID Protection can be challenging because you can get lost in the queue. You can open up a case, but sometimes it can be an hour or even a day between communications."
"The solution is not optimized to work with Mac devices on a granular level. They work seamlessly with Windows but have a lot to improve to work with Mac devices. It also needs to improve stability and scalability."
"I did have some trouble finding specific documentation, particularly for troubleshooting."
"Entra ID lacks a function to synchronize from the cloud to the local directory. This is a significant issue since there is no write-back feature from the cloud to local, which would allow me to use my own credentials from the cloud tenant securely."
"Azure AD could improve by enhancing the availability of specialized courses for security, such as NETSCOUT security or other relevant certifications. It would be beneficial to have specific courses for security, to provide in-depth knowledge and skills related to Azure AD. While there are micro-learning resources available for various concepts, many people in the IT industry may not have the time to go through all the courses to properly configure and utilize Azure Active Directory. Simplifying the implementation process and making it easier for individuals to join a company with Azure AD could also be considered areas for improvement."
"Microsoft has room for improvement in simplifying their integration with third-party solutions and making the licensing model more understandable."
"Integrating some notifications, not necessarily all, but at least for important events or alerts, would be beneficial as it would function as a team solution or something similar."
"I rate the quality of support at four out of ten because of inefficiencies in the ticket handling process. Tickets often bounce from person to person, requiring the sharing of information multiple times."
 

Pricing and Cost Advice

Information not available
"The price of Azure AD is not expensive."
"The product cost is on the expensive side."
"The pricing is competitive in the SMA segment and runs $5-$6 per user."
"Azure Active Directory Identity Protection is not very expensive."
"From one to ten, if one is cheap and ten is expensive, I rate the tool a seven out of ten."
