To prevent any type of external malicious attacks, access to the Ms Sql server is limited only to the machines that are connected to our network.  
Therefore, the connection is guaranteed by the web space on, by a dedicated server and by a Virtual Server, and connection from the outside is not possible as blocked: hence tools like for example Enterprise Manager and Query Analyzer cannot be used nor connections to the host through dynamic functions of certain editors, where the connection will need to be indicated in relation to the localhost and changed when uploading on the server (e.g., Dreamweaver®). 

N.B. We also specify that it is not possible to connect the website in hosting with us to mssql databases which are external to our network.
