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.

Central console enables us to see all of the activated and deactivated computers but it has poor alerts and frustrating technical support
The solution needs to allow for other company product licenses to be included if possible. The solution needs to include other Microsoft products, like Exchange, SharePoint, etc. Right now, it's only for Windows and Office. The solution needs to be made web-based. Right now, we have to install some tools and to use these tools we have to log into a specific server. If that server has an issue we cannot manage it. The solution needs to be able to be managed from any machine. Alerting capabilities should be improved. If a license expires or there is a breach, or something is non-compliant, the solution should send out alerts.
