[1] The principal difference between Xs, Xp and Xg in each case relates to the degree of integration and customization required. For example, Digi-CA Server™ Xs can be pre-configured and delivered to the customer for installation without any assistance from Digi-Sign whilst Digi-CA Server™ Xg projects can run for weeks and even months or years.
Important Note: If you have technical personnel that can correctly configure a network environment, install the necessary operating systems and provide secure access to the server(s), the Digi-CAST2™ installations Team may be able to conduct a large part of the installation process prior to visiting your site. In some cases, the complete installation can occur without the need for Digi-CAST2™ to visit your site at all.
