Sentiment score
7.7
Microsoft Purview eDiscovery boosts ROI by improving data efficiency, compliance, risk management, and reducing legal and IT workloads.
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.
We have seen a 100% return on investment.
The ease of accessing necessary information promptly is the biggest return on investment.
It's hard to quantify the ROI in a dollar amount, but we realize value by doing more tasks in less time than we did before.
 

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
7.6
Microsoft Purview eDiscovery is praised for responsive support, despite some mixed experiences with wait times and outcomes.
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.
I would rate Microsoft Purview eDiscovery's customer service and technical support a ten.
 

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
7.9
Microsoft Purview eDiscovery is scalable and efficient, seamlessly integrating with cloud infrastructures but lacks some search functions.
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 scales with us seamlessly.
With the E3 licensing, I would rate the scalability of Microsoft Purview eDiscovery as a six because it lacks certain critical search functionalities.
 

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
8.6
Microsoft Purview eDiscovery is generally stable, with minor slowdowns, but users seek more transparency on performance issues.
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.
For us, it has been one hundred percent reliable.
Microsoft Purview eDiscovery is highly reliable.
 

Room For Improvement

Microsoft Entra External ID needs improved synchronization, cost transparency, support, software integration, alerting, security, and customization features.
Microsoft Purview eDiscovery needs faster, more efficient features, better integration, NLP for queries, and affordable pricing for users.
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.
Adding more features, as Microsoft continues to expand their cloud offerings, would be beneficial.
Defining what constitutes a credit card because that is where I get the most false positives.
We find that many critical functions are available only to E5 license holders.
 

Setup Cost

Microsoft Entra External ID's costs escalate with growth, complexity in licensing, and heavy dependency on Azure pricing structure.
Microsoft Purview eDiscovery pricing is complex, with E5 costly yet beneficial, while E3 is cheaper but limited.
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.
With CSP or MCE-style agreements with Microsoft, the process is streamlined since we have reps from both Microsoft and CDW working together.
As an M3, I find the Purview pricing of 1250 per user worthwhile.
The pricing and licensing with Microsoft can be complex, and licensing is known to be a challenge because it changes frequently.
 

Valuable Features

Microsoft Entra External ID streamlines management with easy setup, integration, and robust security, enhancing efficiency for diverse application needs.
Microsoft Purview eDiscovery ensures efficient data retrieval with multi-platform integration, automation, compliance visibility, and adherence to global data privacy laws.
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.
The most valuable feature of Microsoft Purview eDiscovery is its ability to search across various platforms, including Exchange, SharePoint, Teams, and OneDrive.
Purview can connect to iOS, Mac, Android, and SaaS apps, which is critical for capturing SMS and MMS text message data.
Purview's inclusion of global regulations is critical because we're heavily regulated by FERC, Sarbanes-Oxley, and the SEC.

Featured Reviews

Corrado Vigano - PeerSpot reviewer
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.
Frank Radeck - PeerSpot reviewer
Tasks that took an entire day before we implemented the solution now take just 30 minutes.
The most valuable feature of Microsoft Purview eDiscovery is its ability to search across various platforms, including Exchange, SharePoint, Teams, and OneDrive. It enables a streamlined, unified process for searching across these platforms. It is critical for Purview to be able to connect to iOS, Mac, and Android devices and data in other SaaS apps. From a support perspective, I can do things while I'm eating lunch or something else. It's more dynamic and responsive. I think everybody appreciates it. We're not tied to one device. Purview's multi-cloud capabilities are also essential for the same reasons. Keeping everything under one umbrella further increases the time savings. Purview accounts for critical regulations from around the world. This is crucial because we hold ourselves accountable to standards and need to align with them. Working at a law firm, we have clients who dictate to us what standards they expect. The visibility is excellent. As we move more things into the cloud, more opportunities exist to put everything under one umbrella.
