To save the cost of purchasing SSL Certificates one by one, you can just put all domains on a Comodo Multi-Domain SSL Certificate, which secures maximum 100 domains on a single SSL Certificate. Also, you can simplify certificate management as you only need to remember a unified expiry date for multiple domains.

The basic certificate covers 3 domains (1 Primary Common Name [CN] + 2 Subject Alternative Names [SANs]). For more SANs, you can pay additional charge to add them on same SSL Certificate.

For example, a Comodo Multi-Domain SSL Certificate can be used to secure:

www.domain.com, mydomain.net, mail.domain.org ......

Comodo Multi-Domain SSL Certificate can be issued in 1-2 business days.

Important Notes:

- To ensure the issuance of SSL Certificate faster, you need to make sure your domain's whois contact information is correct.

- A dedicated IP can be ordered from your web hosting service provider if you want to improve compatibility with older versions of Internet Explorer on Windows XP.

- A CSR (Certificate Signing Request) generated on your web server for your domain. You can contact your web hosting service provider for the assistance of CSR generation and SSL installation
