Head of Sales and Business Development at Axalon GmbH
Flexible with high performance and good reliability
The solution scales well. As an example, there has been an American telecom service provider that had 20 million users, and the data of those user profiles had been stored on Dirx Directory, and they don't have any issues in retrieving the data and using it for any kind of services. Regarding our clients, the amount of users depends on if you have end users that don't really use this Directory or not. They are stored in this Directory and make use of the services that are administered via this Directory. There we are talking about millions. Then, you have administrators who configure the Directory and there we're talking about, let's say, hundreds of users.

Integrated web hosting has simplified secure services and has supported long-term growth
To be honest, I do not see any major areas for improvement. Perhaps something simple and minor. It should not go more complex than it is at the moment. The only disadvantage I see is that the documentation is a bit difficult to find. There is a lot of configuration that is very hard to get information about.
