Multi Domain SSL Saves your Time and Money

The acquisition and management of multiple SSL certificates can be a cumbersome and expensive exercise. Wouldn't life be simpler if you could put all your domains on a single certificate that expired at the same time? A multi domain SSL certificate saves you time and money by allowing you to secure up to 100 fully-qualified domains on one, easy to manage, certificate.

For example, one multi domain SSL certificate can be used to secure:

  • *
