Add SANs to your DV, OV, or EV SSL Certificates to Secure Multiple Domains or Subdomains

Multi-Domain, also referred to commonly as SAN Certificates, utilize Subject Alternative Names (SANs) to secure up to 100 different domain names, subdomains, and public IP addresses, using only one SSL Certificate and requiring only one IP to host the certificate. GlobalSign includes OWA, Mail, and Autodiscover SANs for free with all SSL Certificates. See table below for pricing and support of different SAN types depending on certificate type - DV, OV, or EV.
