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
5.3
Microsoft Entra External ID simplifies identity management despite integration challenges and higher costs, offering time benefits and potential savings.
Sentiment score
6.7
Microsoft Purview DLP offers cost savings, security enhancements, and reduced onboarding time, though ROI varies among users.
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.
 

Customer Service

Sentiment score
5.3
Microsoft Entra External ID support receives mixed feedback, with response times, expertise, and accessibility varying across user experiences.
Sentiment score
5.1
Microsoft Purview DLP support is inconsistent, with quick responses and clear resources but also delays and monopolistic concerns.
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.
Once we got to the Microsoft engineers, the experience was great.
 

Scalability Issues

Sentiment score
7.7
Microsoft Entra External ID is scalable and useful for large companies, but lacks customizable authentication and faces cloud latency.
Sentiment score
7.6
Microsoft Purview Data Loss Prevention offers scalable, flexible cloud solutions, but needs improvements in user-friendliness and device-level scalability.
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.
The policy working and detection technology need enhancements.
 

Stability Issues

Sentiment score
7.3
Microsoft Entra External ID is highly stable and reliable, with users praising its performance and SaaS-only simplicity.
Sentiment score
7.8
Microsoft Purview Data Loss Prevention is highly stable, reliable, and responsive, though minor real-time issues and internal connection challenges exist.
The stability of this solution is very good.
I have not encountered any stability issues with Microsoft Entra External ID.
Unless such major incidents occur, it is stable and reliable.
Sometimes the solution is not stable when the internal connection is not reliable, so this aspect needs improvement.
 

Room For Improvement

Microsoft Entra External ID needs improved synchronization, cost transparency, support, software integration, alerting, security, and customization features.
Microsoft Purview DLP needs better integration, improved UI, enhanced AI features, cost-effective licensing, and better language 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.
Implementing a degree of severity ranking is essential.
Endpoint Data Loss Prevention needs to be improved as it is not up to expectations.
 

Setup Cost

Microsoft Entra External ID's costs escalate with growth, complexity in licensing, and heavy dependency on Azure pricing structure.
Microsoft Purview DLP in E5 licenses offers competitive pricing and flexible payment, valued for security features and added services.
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.
 

Valuable Features

Microsoft Entra External ID streamlines management with easy setup, integration, and robust security, enhancing efficiency for diverse application needs.
Microsoft Purview DLP enhances data security with auto-labeling, multi-cloud support, cross-platform protection, and strong compliance features.
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 Purview Data Loss Prevention usually performs well, except for endpoint Data Loss Prevention, which may need improvements.
The feature I find most valuable that I'm currently using is the quickness of the emails that the Microsoft Purview Data Loss Prevention solution sends to us, where we get notifications that say a user has potentially breached our data guideline rules, and we get those alerts continuously, allowing us to enforce them manually.

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.
Roby Skariah - PeerSpot reviewer
Automation has given us consistent analytics and improved quality of insights into user activity
One of the valuable features of Purview is the ability to create a legal hold on a user's account within the compliance portal. That's pretty useful when it comes to any litigation or if you want to redeem the content within a mailbox, OneDrive, or a generic public SharePoint site. If you want to retain the user's data until the case is resolved, you can use the legal hold feature. Also, it's important that Purview can connect to iOS, Mac, and Android devices. With smartphone involvement, so many applications can now be accessed through them and it is important to apply Purview across operating systems and platforms. Purview's natively integrated compliance across Azure Dynamics and Office 365 is also significant because within Microsoft 365 there are multiple applications. Irrespective of whether it's Dynamics or Azure, it's very important that it has native support. The data connectivity should be efficient enough to support and secure their own platform's data. In addition, with varying regulations in different industries and matters, Purview lets you create rules and conditions based on industry standards around the world. That is important. Our company is in pharmaceuticals and the rules and conditions are different from other industries. It is important to be able to keep track of all these regulations and have a tool that is flexible enough to create the regulatory rules and conditions we need. And when it comes to data loss protection, Purview has features that can recognize patterns and detect any sort of data loss, where the data is being transferred from its platform to a different one. The default settings that come with it are pretty nice for identifying data transfer or data loss across the platform. It also comes with a lot of training materials, with use cases and examples, to help educate users and make them familiar with the tool.
