The Basic EV SSL Certificate offers great long-term scalability by allowing you to add up to 250 standard domains now or later – all under one single certificate. This will simplify certificate management immensely! (This certificate is more customizable than a multi-domain SSL certificate, because you can secure 1 or 2 domains now instead of the traditional 3 domain starting point.)
In addition, this is an extended validation (EV) SSL certificate – the highest level of validation you can receive. This will be a major boost to your website as users can verify your organizational information right in your certificate details. When you couple this with the complementary DigiCert Dynamic Site Seal, you are sure to build more trust with your users.
