Multi Domain SSL Certificates


A trusted SSL certificate proves the authenticity of your website through the reliable verification of your domain and additional company information. Operating systems and browsers also show that your website is secure.


With multi domain SSL certificates, up to 20 domains with or without unlimited subdomains and sub-subdomains can be flexibly protected with a single certificate.


Multi domain certificates can also be issued at EV (Extended Validation) level.

Choice of validation level

Depending on the certificate type (SSL Gold Multi-Domain (OV), SSL Gold Multi-Domain (EV)), different attributes of the certificate holder are checked.


For the identification verification of multi domain SSL certificates, a distinction is made between two main types.

Organisation Validation (OV)

The Organisation Validation (OV) certificate type checks the organisation, i.e. the company operating the site. It also checks the official entry and confirms that the specified organisation actually exists. This information is indicated in the certificate. This ensures that the organisation is also the legal user. 

Extended Validation (EV)

The Extended Validation (EV) certificate type is checked according to the strict, internationally regulated EV guidelines of the CA/Browser Forum. The checking process includes legal and operational checks and validation of the existence of the company by a state register, comparison with the official applicant information, authorisation of the certificate requester and the authentication of the owner rights for the domain.
