Frederic Hautecoeur - PeerSpot reviewer
Senior System Integrations Architect at bs-team
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.
