Secure hundreds of domains, subdomains, or IP addresses using Subject Alternative Names with one flexible SSL certificate

Multi-Domain Certificates, also called SAN certificates, offer complete control over the Subject Alternative Name field. These certificates are ideal for securing multiple names across different domains and subdomains (e.g., Exchange/OCS environments). You also have the option to add, change, and delete any of the SANs on the fly to reflect the evolving needs of your network. Run multiple services on one IP address and use a multi-domain (SAN) certificate to secure:

  • OWA
  • SMTP
  • Autodiscovery
  • ActiveSync
  • Outlook Anywhere
