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.

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.

Quotes from Members

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

Pros

"The single sign-on access is the most useful feature we use."

"It's quite easy to manage and monitor."

"The fact that it is quite integrated into the entire Microsoft environment makes it quite easy to use."

"It's similar to using a Microsoft account to create accounts on other websites. We are also using Microsoft Entra to monitor which applications our guests are using. This allows us to filter, block, or adjust permissions for these applications as needed for our collaborators."

"The most valuable feature for me is the firewall capabilities."

"Microsoft Entra External ID is more secure, offering a secure environment."

"The most valuable feature for me is the firewall capabilities."

"The fact that it is quite integrated into the entire Microsoft environment makes it quite easy to use."

More Microsoft Entra External ID pros

"The tool has been beneficial. Some of our previous users left the organization without sharing the information they had at a personal level. This information was related to the organization, and they didn't disclose it. Thanks to the product, it's easy for me to search and find out what communication a specific user has done, whether it's from SharePoint or any other platform. With Microsoft Purview eDiscovery, we can easily retrieve and restore this data."

"Purview eDiscovery has made it significantly easier to handle rare litigation requests."

"The speed of it is valuable. I am able to search even 10,000 mailboxes for specific content. It helps search and accommodate the often limited information provided by users regarding what they need."

"The return on investment is saving the equivalent of one or two full-time IT department employees and a few hours per week for legal staff."

"Microsoft Purview eDiscovery has saved me personally a lot of time because I can query it, and it touches everything we have as a full Microsoft shop."

"Our legal team benefits from using Microsoft Purview eDiscovery."

"Tasks that took an entire day before we implemented Purview now take just 30 minutes."

"I think eDiscovery Premium has made dealing with data from Teams much more accessible than any other platform."

Cons

"Microsoft's pricing is complex and difficult to fathom due to a range of different licensing options."

"The cost is very high."

"There is room for improvement in AI technology for Microsoft Entra External ID, particularly in providing detailed alerts."

"I generally find Microsoft solutions expensive, especially in specific offerings."

"Technical support needs improvement."

"The problem with Microsoft products is that they often cater to enterprise-level needs, which can be too costly for medium-sized businesses."

"Single sign-on for external applications such as Oracle could be improved to be a little bit cheaper."

"A common concern among the customers I visit is the unpredictability of Microsoft's costs at every renewal. This is really bothersome for the customer, and I would say it is the worst element I have seen in these years."

More Microsoft Entra External ID cons

"It has been one of the most solid tools I have worked with. However, Purview Data Loss Protection for remediating policy violations needs refinement, for example, in defining what constitutes a credit card because that is where I get the most false positives."

"I see two significant challenges with many of my clients. One is that there are some functionality gaps compared to specialized tools in the legal industry, like a legal hold tool or a document review tool. They have features that Purview eDiscovery lacks. Those gaps create a situation where I almost have to do things twice. I need to collect all my data in eDiscovery and ship it to another platform to complete the review."

"Purview eDiscovery works, but it's not entirely perfect. There were times when search results would get hung up or error codes would be presented and we'd have to contact Microsoft to get that sorted out."

"I would suggest adding more platforms."

"The query language can be time-consuming to figure out if you don't know it initially. While there are options with dropdowns to select criteria, having a natural language feature would be beneficial. Copilot is expected to add such functionality in the future."

"We find that many critical functions are available only to E5 license holders. It would be beneficial to have more options available for E3 customers. Enhanced Teams functionalities and better capture of text message data, both SMS and MMS, would also be improvements."

"The query language can be time-consuming to figure out if you don't know it initially."

"Microsoft Purview eDiscovery should be cheaper."

Pricing and Cost Advice

"We don't pay separately for Microsoft Entra External ID as it's part of our Microsoft Exchange subscription."

"With the full bundle, pricing is not a significant concern. As an M3, I find the Purview pricing of 1250 per user worthwhile."

"In the positions that I've had through contracting over the years, I've heard talk of it being overpriced and underperforming compared to its competitors."

"The costs associated with E5 licensing are currently expensive for us, so we use the E3 license, which comes with fewer features and functionalities."

"Microsoft Purview eDiscovery comes as part of Microsoft 365 licenses."

"The pricing and licensing with Microsoft can be complex, and licensing is known to be a challenge because it changes frequently. While the licensing for Purview is not as tricky as other Microsoft products, navigating licenses since the shift to E3 and E5 plans has been a task, as individual licenses must now be purchased separately."

Overview

Microsoft Entra External ID, part of Microsoft Entra, provides highly secure digital experiences for partners, customers, citizens, patients, or any users outside your organization with customization controls. Combine external identities and user directories in one portal to seamlessly manage access across the organization.

Microsoft Entra External ID refers to all the ways you can securely interact with users outside of your organization. If you want to collaborate with partners, distributors, suppliers, or vendors, you can share your resources and define how your internal users can access external organizations. If you're a developer creating consumer-facing apps, you can manage your customers' identity experiences.

With External ID, external users can "bring their own identities." Whether they have a corporate or government-issued digital identity, or an unmanaged social identity like Google or Facebook, they can use their own credentials to sign in. The external user’s identity provider manages their identity, and you manage access to your apps with Entra ID or Entra External ID to keep your resources protected.

The following capabilities make up External ID:

B2B collaboration - Collaborate with external users by letting them use their preferred identity to sign in to your Microsoft applications or other enterprise applications (SaaS apps, custom-developed apps, etc.). B2B collaboration users are represented in your directory, typically as guest users.
B2B direct connect - Establish a mutual, two-way trust with another Azure AD organization for seamless collaboration. B2B direct connect currently supports Teams shared channels, enabling external users to access your resources from within their home instances of Teams. B2B direct connect users aren't represented in your directory, but they're visible from within the Teams shared channel and can be monitored in Teams admin center reports.
Azure AD B2C - Publish modern SaaS apps or custom-developed apps (excluding Microsoft apps) to consumers and customers, while using Azure AD B2C for identity and access management.
