Executive Summary

Review summaries and opinions

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

ROI

Sentiment score
4.3
Users faced challenges with Microsoft Entra External ID but saved costs and time compared to traditional, on-premises solutions.
Sentiment score
7.4
Microsoft Purview enhances protection, automates compliance, reduces response time, and supports growth, though exact savings are hard to quantify.
It has led to cost savings as well as time savings because I can use a single solution for all applications.
Companies can leverage it for setting up external identities without needing to develop their own solutions.
In terms of return on investment, prior to using this product, our company managed our own mail server with all internal authentication happening on premises, resulting in a ROI in the thousands every year.
Purview can do a quick scan, and it doesn't use human resources, so it gets time to do things that we need humans to focus on.
The E5 license comes with different solutions like data discovery classification, CASB, DLP solutions, and Defender for Cloud.
The cost of data loss and your data going to a competitor is potentially massive.
 

Customer Service

Sentiment score
4.3
Microsoft Entra External ID support varies; response times, documentation, and regional differences affect user satisfaction and solution accessibility.
Sentiment score
4.4
Users experience inconsistent Microsoft Purview support, citing slow responses and unresolved issues, despite some improvements in visibility and engagement.
Companies without a Microsoft license for Entra ID or Azure portal cannot add Azure AD B2C, creating logistical issues for some of my clients who are unable to evaluate the platform.
The support for business applications, infrastructure support, and Entra has been mostly positive with highly skilled technicians.
The documentation is very thorough, reducing the need for support.
Sometimes, I get a fast and knowledgeable response, while other times, I've experienced delays and received no resolution.
It's hard to be an ambassador for a product when you know it will be hard to get support.
After our issues are reported, it takes a long time to find a resolution.
 

Scalability Issues

Sentiment score
7.0
Microsoft Entra External ID offers scalable security for large enterprises, with distinct policies and strong performance despite some latency issues.
Sentiment score
7.4
Microsoft Purview Information Protection is praised for scalability despite some concerns with data analytics speed and policy update intervals.
This is one of EID's weak points compared to Azure AD B2C, which offers customizable authentication options, including attribute and password combinations.
End-user workloads experience increased latency in a cloud environment compared to on-premises resources.
Microsoft Entra External ID is quite scalable, and I would rate its scalability between eight and nine out of ten.
It can be scaled across different departments organization-wide very quickly and easily.
It can handle large collections of data without issues.
Scalability can be improved by reducing these intervals.
 

Stability Issues

Sentiment score
5.7
Microsoft Entra External ID is highly stable, reliable, and smooth, with minor rare issues, and positive user feedback.
Sentiment score
7.4
Microsoft Purview is stable and reliable, with minor delays and occasional drawbacks, fostering user trust and wide deployment.
I'd rate the stability of the Microsoft Entra External ID as a 10.
The stability of this solution is very good.
I have not encountered any stability issues with Microsoft Entra External ID.
Once implemented, I haven't had issues with its consistency.
The product is stable, and whatever it does, it does better than any other thing.
The solution is stable overall.
 

Room For Improvement

Microsoft Entra External ID needs improved support, integration, pricing, security, UI, and customization for medium-sized businesses.
Microsoft Purview requires better integration, pricing, navigation, and feature enhancements to address user concerns about functionality and support.
This is particularly challenging during enterprise agreement renewals, as it's difficult for customers to review costs leading to lengthy negotiations.
Enhanced customizable login options and the ability to use attribute password logins are critical features that are required for Microsoft Entra External ID to gain dominance in the authentication market.
I would like to see a more detailed alert system that provides a summary of why alerts are generated, who is generating them, and the reasons behind it.
Effectiveness in Microsoft Purview Information Protection means enforcing the policy and making sure it works consistently across non-Microsoft products as well.
Having a roadmap or updates about new releases would be helpful for demonstrating to clients.
Clarifying product features and use cases would help avoid such confusion.
 

Setup Cost

Microsoft Entra External ID pricing is complex, potentially costly, but scalable, benefiting from Azure expertise and existing subscriptions.
Microsoft Purview offers competitive pricing, flexible enterprise licenses, and cost-effective bundled solutions, despite some complexity in licensing options.
Regarding pricing, the cost seems high for single sign-on, especially for external applications like Oracle.
Microsoft's pricing is complex and difficult to fathom due to a range of different licensing options.
The cost can be a factor for Microsoft Entra External ID, but in general, it offers a scalable and efficient solution compared to deploying individual solutions.
I talked to people who had compared it to other products on the market, and they're spending five figures to get started.
The E5 license covers most of the solutions for different technologies, so that way, it is good and more affordable compared to any other solution.
Our focus is on helping customers maximize their software investment.
 

Valuable Features

Microsoft Entra External ID enhances security, management, and user experience through integration, single sign-on, and adaptive authentication features.
Microsoft Purview enhances data protection with encryption, automated labeling, and compliance, excelling in Microsoft ecosystem integration and management.
It is crucial for hybrid environments, especially for integrating existing on-site infrastructures with cloud-based Active Directory, such as in Office 365 implementations.
EID unifies workforce users with external business partners, which is a very strong feature.
Microsoft's reliability in providing a clear roadmap for the solution is very important, especially at a time when cybersecurity is a risk in every company.
Microsoft Copilot is an advantage because it's enterprise-grade AI.
It's paramount to have a single solution for information protection.
Regardless of the education, the employee might share the information anyway, so the AI shouldn't be the first point of failure. It should be a human making good decisions.

Solution integrates well with existing systems while being easy to use
The fact that it is quite integrated into the entire Microsoft environment makes it quite easy to use. Furthermore, Microsoft's reliability in providing a clear roadmap for the solution is very important, especially at a time when cybersecurity is a risk in every company. The solution is easy to reuse and not difficult to find expertise for in the market because it is widespread. It is gaining attention even from partners and from the market on the offering side. This serves as a good starting point for customers who can develop internal competence on the solution. Additionally, the presence of reliable partners who know the solution and can provide internal knowledge is the best aspect for them.
Abhi T - PeerSpot reviewer
Achieve comprehensive data protection with reliable performance and room for enhanced discovery accuracy
The product is still in a growing phase. I could see that many use cases in their product are not capable enough in terms of detecting or protecting. Compared to other products, they are in the middle of bringing their solution up to the mark, so it is not a full-grown solution. They have to get more accurate results in terms of data discovery and classification. The second thing is their support; support from Microsoft takes a lot of time to get a response from their support team. The third thing is their OCR capability is not that great in terms of identifying the documents. We would love to see response times of less than 24 hours. Additionally, there is no way to check the policy's current status in terms of whether it got synced or not. You have to wait and test the use cases after 24 hours or after 48 hours, and once it starts working, then it appears the policy got implemented.
