Comparison Buyer's Guide

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 saves time and costs despite lacking monetary gains compared to competitors like Okta.
Sentiment score
7.4
Microsoft Purview enhances compliance, security, and efficiency by automating document protection, centralizing assets, and reducing tool redundancy.
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
5.3
Microsoft Entra External ID service shows varying performance, affected by staff, documentation, and contract size, especially for smaller enterprises.
Sentiment score
4.4
Microsoft Purview Information Protection's customer service receives mixed reviews, with criticisms on responsiveness and praise for recent improvements.
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
7.7
Microsoft Entra External ID is highly rated for scalability and performance, with strong security and flexibility features for large organizations.
Sentiment score
7.4
Microsoft Purview Information Protection offers reliable scalability, efficiently handling large data volumes, though improvements in data processing speed are needed.
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
7.3
Microsoft Entra External ID is highly rated for stability and strong performance, with untested adaptive authentication features.
Sentiment score
7.4
Microsoft Purview Information Protection is stable, reliable, with minimal issues, though processing large documents can be slow occasionally.
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.
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 better support, cost clarity, security, integration, and improved single sign-on pricing for medium enterprises.
Microsoft Purview Information Protection requires better third-party visibility, reporting, AI integration, PDF support, and accurate policy enforcement.
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's pricing is complex and can be costly without Azure knowledge, requiring clearer understanding.
Microsoft Purview Information Protection is competitively priced, appealing for its comprehensive suite and flexible licensing options despite complexity.
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 simplifies integration with features like single sign-on and centralized management, enhancing security and operational efficiency.
Microsoft Purview offers comprehensive data protection with automatic classification, sensitivity labels, and seamless integration across platforms for robust compliance.
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.
Heidi Hasting - PeerSpot reviewer
Provides an essential audit trail that helps prevent accidental exposure of sensitive data, but the changing product names are confusing
One of the key features of Microsoft Purview Information Protection is the auto-classification functionalities, although I have found them to be less effective in complex scenarios. The policy toggle, demanding justification for downgrading labels, provides an essential audit trail that helps prevent accidental exposure of sensitive data. The security tools integrate well. I like that you can scan several data or informational assets, such as your SharePoint list, Teams, etc., and bring them into Purview as a central repository. Partnering with other products, like Sentinel, for logging capability and inventory provides a service across the board. It's essential that Purview automatically prevents highly sensitive corporate secrets and data from being ingested into generative AI models, but the reality is that AI is a tool. It's problematic if consumers rely on a tool to protect them because they must be educated first. 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.
