Server Xg Requirements

Certificate Authority Requirements

PDF The Digi-CA™ Server Xg is completely customizable and can be installed across many servers, even if they are in different locations. A Trust Centres example would use four servers and if the correct internet connection and a VPN can be provided to the server, it is possible that much of the installation of the software can be carried out virtually. However, the Digi-CA™ Server Xg will require at least one site visit from a Digi-CAST™ Team Member to conduct certain specialist tasks.

The benefit of using the VPN connection as much as possible is that it reduces the cost of travel and accommodation. When examining each of the following three sub sections you can consult with the Digi-CAST2™ Team at any time to check configurations and access for you.

Digi-CA™ Server Xg is supplied ready for total installation on the desired number of servers. There is no requirement for any Operating System [OS] or pre-configuration, whatsoever. In fact, if the servers are not completely free of any OS or software, they must be formatted to return them to their original ‘as manufactured’ state.

            • OpenSSL
            • mod_SSL
