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."
"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."
"What I like is that I can go anywhere, at any time, and to any client premise, and I can simply log in to the admin panel and can serve any of my clients."
"The ability to speed up ability is an asset."
"The most valuable feature for us is the B2C functionality of Microsoft Entra ID, which is essential due to our need for external and internal users to log into our system."
"The most valuable feature for me is enterprise applications. This functionality allows the building of applications that are tied into APIs that we can grant specific permissions and limit the scope of access."
"I would say that Azure AD's pricing is very reasonable because of the structure and in terms of the solution."
"We use BitLocker for policy enforcement. And now, because of the Microsoft 365 Business Premium package, we get Intune as a part of it. That's very useful for us for setting policies and managing the systems. The biggest strength of Azure AD is Intune."
"The best feature of Microsoft Entra ID is that it provides more granular control over user identities."
"The most valuable features of this solution are security, the conditional access feature, and multifactor authentication."
 

Cons

"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."
"Further integration across different Microsoft products would be an improvement."
"Private access and internet access should be available in a less expensive licensing model."
"There is a concept of cross-tenant trust relationships, which I believe Microsoft is actively pursuing. That is something which in the coming days and years to come by will be very key to the success of Azure Active Directory, because many organizations are going into mergers and acquisitions or spinning off new companies. They will still have to access the old tenant information because of multiple legal reasons, compliance reasons, and all those things. So, there should be some level of tenant-level trust functionality, where you can bring people from other tenants to access some part of your tenant application. So, that is an area which is growing. I believe Microsoft is actively pursuing this, and it will be an interesting piece."
"The quality of support is regular. If you contact Microsoft support directly for Microsoft Entra ID, it's faster, but when you do it through a partner, it takes more time."
"The licensing cost is a bit prohibitive."
"Microsoft Entra ID can be improved by having more resources for learning how to best use the tool and understanding best use case scenarios. The learning curve is challenging, so I would appreciate seeing a training portal that is easier to use."
"Entra ID has limited integration with non-Microsoft solutions like iOS or Ubuntu. If it worked across different software and all kinds of devices could be managed under it, that would be great."
"Whatever business requirements we needed in the past three years, users were created, with the name of the user and they were not connected with the Active Directory. We were trying to in house in three years and with directory, but we were not able to achieve it."
"The Azure AD Application Proxy, which helps you publish applications in a secure way, has room for improvement. We are moving from another solution into the Application Proxy and it's quite detailed. Depending on the role you're signing in as, you can end up at different websites, which wasn't an issue with our old solution."
 

Pricing and Cost Advice

Information not available
"If you have a different IDP today, I would take a close look at what your licensing looks like, then reevaluate the licensing that you have with Microsoft 365, and see if you're covered for some of this other stuff. Folks sometimes don't realize that, "Oh, I'm licensed for that service in Azure." This becomes one of those situations where you have the "aha" moment, "Oh, I didn't know we can do that. Alright, let's go down this road." Then, they start to have conversations with Microsoft to see what they can gain. I would recommend that they work closely with their TAM, just to make sure that they are getting the right level of service. They may just not be aware of what is available to them."
"The pricing is good; it's not cheap but very reasonable."
"It can be a bit expensive for organizations, but they do have different pricing models. Their free tier can be used on a personal level, but for an organization, the licenses might be a bit expensive. In general, the licenses can become cheaper, which will make it accessible for more people."
"Microsoft Entra ID service can be quite costly due to its hidden expenses linked to usage."
"It's really affordable."
"Entra ID is not too bad, but Microsoft licensing generally is insane. Most customers normally buy a bundle license with Microsoft 365, E3, or E5. Out of our 2,000 customers, for 99.9% of our customers, the Entra ID license that they are getting through the part of that would be sufficient. There are some more advanced ones that give you a bit more functionality, but we probably have not had a customer for that. We do not even internally use that ourselves. When you buy the Entra ID license on its own, it is probably three or four pounds. You just get it included in the license."
"The licensing model makes it difficult to understand the real cost of the solution, especially because it changes all the time."
"The product's price is in the midrange."
