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.

Cons

"I would like to see features around federation, authentication, authorization, and AI APIs with a ChatGPT interface."
"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 faster synchronization."
"Microsoft's pricing is complex and difficult to fathom due to a range of different licensing options."
"I generally find Microsoft solutions expensive, especially in specific offerings."
"The only problem that you might face with Microsoft now is their complex licensing model."
"The authentication methods available are very limited, and this presents a weak point."
"Technical support needs improvement."
"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 tool is cheaper compared to typical German products. I rate the product’s pricing a four out of ten."
