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…
Bahram Piri - PeerSpot reviewer
Security focus and seamless implementation increase platform productivity
Microsoft Entra ID can be improved in many ways, and there's a big wish list.If we're focusing on security, something that I definitely expect is improvement in the UI and UX for frontline workers. This is important, especially for non-tech savvy individuals. It is something Microsoft Entra ID could do to improve for a wider audience. It's important to focus on the frontline workers since they are non-tech savvy individuals. They are not like those back-office engineering C-level employees who are constantly dealing with computers, and we need to build a specific user experience and user interface for them to handle this stuff. That's something I expect Microsoft to focus on more for Microsoft Entra ID.

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."
"Using [Azure AD's] passwordless technology, you're not even using a password anymore. You're basically just creating a logon request without actually sending or typing or storing the password. This is awesome for any user, regardless of whether you're a factory worker or a CFO. It's secure and super-simple."
"Microsoft Entra ID is pretty user-friendly and intuitive. The graphics are particularly useful when it comes to the auditing part."
"The security features, such as attack surface rules and conditional access rules, are the most valuable aspects of Azure AD."
"It has been very instrumental towards a lot of services we run, especially on the single sign-on side. For example, we have 160 countries that all run their own IT but we still are able to provide users with a single sign-on experience towards global applications. So, they have a certain set of accounts that they get from their local IT department, then they use exactly the same account and credentials to sign into global services. For the user, it has been quite instrumental in that space. It is about efficiency, but also about users not having to remember multiple accounts and passwords since it is all single sign-on. Therefore, the single sign-on experience for us has been the most instrumental for the end user experience."
"It is very simple. The Active Directory functions are very easy for us. Its integration with anything is very easy. We can easily do third-party multifactor authentication."
"Entra has made it easy to manage identity and access by integrating with all Microsoft services."
"The benefits of using this solution were realized straightaway."
"It is a really nice tool and we have a license for the more complex model."
 

Cons

"Further integration across different Microsoft products would be an improvement."
"The integration is not as seamless compared to competitors like Palo Alto."
"With Microsoft, support is always crazy, it's not easy to get support."
"Azure Active Directory could benefit by adding the capability for identity life cycle for the on-premise solution. For example, an HR solution, which is built on-premise or, in general, better on-premise capable solutions."
"The deadlines for this feature were set for March, and that has already passed without deployment. We commented that we are still waiting for that, and they commented that they would update us when it is finished, but we haven't received any update about it."
"The downside is that we now have all our eggs in one basket with Microsoft. We have this great authentication and single sign-on, but if Microsoft has an outage in North America or globally, on Outlook or Teams, we're dead in the water... We get some type of hiccup once a quarter."
"Microsoft services and most familiar third-party applications are currently supported, but we can't find many other platforms that integrate with Office 365 or Azure Active Directory. Microsoft should develop connectors for different applications and collaborate more with other vendors to cover a broader range of applications."
"I think the solution can improve by making the consumption of that data easier for our customers."
"I would like to see Microsoft communicate how they intend to manage legacy applications. Right now, you still have to deploy a hosted domain server (which comes at an extra cost) if you have a legacy application that cannot sync properly with the enterprise applications and the modern applications."
"Reading documentation could be simplified. Technical support could also be faster."
"It doesn't function the same way as an Active Directory inside of an infrastructure, that is, a physical infrastructure. In the cloud, it is all flat. That's one of the disadvantages."
 

Pricing and Cost Advice

Information not available
"The price of Azure Active Directory and Amazon AWS, are almost the same, but most people prefer Amazon AWS because they find it's a little cheaper to some extent and an easier platform to use."
"The pricing depends on the use case and can be negotiated based on volume."
"Its price is okay. It is easy to go from P1 to P2 license. It is not exactly a bargain, but I would recommend the P2 license."
"It's relatively inexpensive in comparison with third-party solutions. It's highly available and supported by Microsoft Azure in our enterprise agreements. With the addition of their B2C tenants, it's hard to beat from a cost perspective now."
"The price is fine. It's a good value for the money compared with other solutions."
"There are add-on components and services, such as identity services, that we have to add to our Azure subscription. Only then can I actually say it's on par with the on-prem server edition. Why should I pay for a component? It should be included in my subscription."
"I give the cost a three out of ten."
"Active Directory is bundled with a package of Microsoft services, so it doesn't cost much. I don't know about the individual license of Active Directory."
