Offers strong identity unification but needs better customization

Microsoft Entra External ID can be improved with additional features, specifically customizable flexibility and a customizable user interface for the login dialog. Currently, the login dialog has very limited customization options, which only include font styles, colors, text messages, or brand icons. Last month, Entra ID introduced some customizable features in their login dialog, but this does not apply to Microsoft Entra External ID, indicating a significant gap between the two. In theory, Entra External ID can support many external identity providers where custom login dialogs could be integrated, potentially via SSO feature coordination, although I have not yet confirmed this. Hence, 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.

Offers single sign-on capabilities to users

Suppose you are totally dependent and have requirements where you have a cloud application or several applications for integration with the cloud. In that case, I will suggest the use of Oracle Identity Cloud Service. Oracle Identity Cloud Service has much scope for customization. If you have a high customization level, then I would suggest IAM. The tool's multifactor authentication capabilities are easy to implement. If a client has a banking system, they need a strong authentication service, and only a password is not required; the user has to authenticate via fingerprint, face recognition, or go for or any RSA token. Double authentication is required where the banking department has access to very critical applications, or else they cannot go ahead and give the password. It is very difficult to hack once you have MFA in place. You have to either give the print fingerprint or any RSA token, making it not so easy to hack the system. We suggest MFA to clients who have the most critical application with them. I recommend the tool for every client we have, but it depends on how they want to have it because some customers don't want to go for the cloud application, and they might be thinking about changing the cloud vendors. Suppose a company has some costs in mind, and if they have a large number of employees, like 50,000 or 1,00,000 users, then it will be costlier for them than having an on-prem tool, like IAM. If a customer has 5,000, 10,000, or 20,00 employees, Oracle Identity Cloud Service can be a cheaper tool than the IAM product. I will suggest Oracle Identity Cloud Service only for smaller organizations. The tool does not have any AI capabilities. I would recommend the tool to everyone. I rate the tool an eight out of ten.

Quotes from Members

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

Pros

"When it comes to Microsoft Entra External ID, Microsoft itself is the best distributor."

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

"The best features of Microsoft Entra External ID include its unification of B2C functionality and B2E features."

"The times that I have gone into it, I found it easy to use and I haven't had any issues with it."

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

"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."

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

More Microsoft Entra External ID pros

"The APIs are well documented, which has allowed us to access the IDCS security applications in our custom APIs."

"Federation and Identity let us create users and send federation tools, giving the authentication and authorization to users. With the on-premise solution, I can do the installation, configuration, and integration of Identity Access Management. This gives us direct access. The integration with the single solution E-business suite is also very valuable."

"The most valuable features are the high stability and good performance."

"Onboarding of new employees, consultants, and partners has rapidly increased. We reduced the time to onboard them and the ease of onboarding has been improved. Therefore, we recognize there has been efficiency which has been brought into our organization."

"The most valuable feature is the reduced maintenance burden for the client."

"Identity Cloud has simplified our migrations. Since we're primarily working with native Oracle solutions, we can adopt many features of Oracle Identity Cloud Management."

"The most valuable feature is identity management."

"The tool's most valuable feature is its single sign-on capabilities."

Cons

"The only problem that you might face with Microsoft now is their complex licensing model."

"There have been a couple of times when it was unavailable because of Microsoft issues, but other than that, I don't remember any problems."

"The training generally is complicated to understand, leading us to often go through a managed service provider."

"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."

"The authentication methods available are very limited, and this presents a weak point."

"I would like to see faster synchronization."

"The support engineers are not as skilled as our engineers. When they say something would not work, or there is no solution, we usually hear that Microsoft would not support this."

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

More Microsoft Entra External ID cons

"We still see a lot of bugs in any of the versions that Oracle comes out with. So, there are a lot of bugs that need to be fixed."

"The protocol could be easier to use."

"Self Service features are still limited in IDCS, and there is a need for more customization of the self-service screens."

"Oracle needs to improve the GUI and many other aspects of the cloud console. It isn't as slick as Azure, Google, or IWS cloud. The documentation could be better, too."

"The initial setup was a little complex. At that time, the method of integration was a bit complicated due to the scripts that we were required to write for the integration."

"The tool doesn't have many out-of-the-box connectors for the target integration."

"The IDs that are not used for a particular number of days should be disabled automatically."

"The cost of this solution should be reduced."

Pricing and Cost Advice

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

"The foundation tier that is offered with other cloud services subscriptions is fairly extensive and supports the use of identities, groups, and privileges in those cloud services."

"Our licensing costs are on a yearly basis."

"The tool's implementation costs totally depend on the number of users. The cost depends on how many users are going to use it, so a per-user cost model is needed for the tool."

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.
