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.

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.

Pros

"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."
"Most of the features are related to banking within this particular IT industry. Security and the market are also important features."
"The single sign-on access is the most useful feature we use."
"It's quite easy to manage and monitor."
"I have not encountered any stability issues with Microsoft Entra External ID."
"The fact that it is quite integrated into the entire Microsoft environment makes it quite easy to use."

"The most valuable feature for me is the firewall capabilities."
"Primarily Microsoft Entra External ID SSO is valuable as it works with everything when it comes to integration."

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 cost is very high."
"Technical support needs improvement."
"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."
"The training generally is complicated to understand, leading us to often go through a managed service provider."
"There is room for improvement in AI technology for Microsoft Entra External ID, particularly in providing detailed alerts."
"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 problem with Microsoft products is that they often cater to enterprise-level needs, which can be too costly for medium-sized businesses."
"I generally find Microsoft solutions expensive, especially in specific offerings."
