Facilitates improvement through feedback collection, quizzes, and event data generation
Gluu has a mobile app catering to field workers. Normal workers use the web app, a complete cloud-based solution. They log in on any device and access the system. Gluu filters and displays relevant information based on the user's role in the processes. Users can set it up to view as a viewer, worker, manager, or controller of the area. The front end offers different views but provides an easy dashboard for employees. On the dashboard, users can configure it to show tasks, related work instructions, and connected processes. It's very user-friendly, allowing end-users to understand their tasks and processes without needing in-depth knowledge.

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.

Quotes from Members

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

Pros

"Most of the features are related to banking within this particular IT industry. Security and the market are also important features."
"Gluu has a mobile app catering to field workers. Normal workers use the web app, a complete cloud-based solution. They log in on any device and access the system."
"The most beneficial feature for us is the ease of setup. With about five clicks, we can generate unique IDs and keys and set up in less than 30 minutes. We can also generate these for multiple years simultaneously, which is convenient."
"The positive impact of Microsoft Entra External ID on my organization is that it enhances ease of use for the administrative side."
"I have not encountered any stability issues with Microsoft Entra External ID."
"It's quite easy to manage and monitor."
"Microsoft Entra External ID offers numerous advantages; there's no need to maintain anything on-premises, which results in a significant IT infrastructure cost saving."
"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 experience has been rather good; there are other possibilities, but we made the choice to go with Microsoft, and we have a good experience with that."
 

Cons

"The tool integrates AI into the process modeling aspect. I believe this addition will significantly enhance usability. Additionally, it might be beneficial to have the capability to import content from other tools into this platform. Our platform follows its business process modeling notation standard, which differs from BPM. It uses a simpler notation, making it easier. The ability to import content from other tools could accommodate users accustomed to different standards."
"I would like to see features around federation, authentication, authorization, and AI APIs with a ChatGPT interface."
"The quality of Microsoft customer support varies. With an enterprise contract, good resources are usually provided, especially in regions like Saudi Arabia or UAE. However, we have faced challenges with support quality, especially in some subcontinent areas where the resources might not be as experienced."
"The problem with Microsoft products is that they often cater to enterprise-level needs, which can be too costly for medium-sized businesses."
"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."
"There is room for improvement in AI technology for Microsoft Entra External ID, particularly in providing detailed alerts."
"Single sign-on for external applications such as Oracle could be improved to be a little bit cheaper."
"As of latest, when it comes to my experience, I am not satisfied."
"The authentication methods available are very limited, and this presents a weak point."
"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."
 

Pricing and Cost Advice

"The price is reasonable."
"The tool is cheaper compared to typical German products. I rate the product’s pricing a four out of ten."
"We don't pay separately for Microsoft Entra External ID as it's part of our Microsoft Exchange subscription."
