Choose the right certificate

The right SSL certificate depends on which domain names you need to protect, not the validation type. Start with your names, and we will find the cheapest match.

1

Single domain?

E.g. www.yourcompany.com + yourcompany.com

If you only have one domain (with and without www), a simple DV certificate is the cheapest and fastest solution. These automatically include both www.domain.com and domain.com.

Tip: Order the certificate for www.yourcompany.com as the primary name, then yourcompany.com is included automatically for free. If you only order yourcompany.com, it only covers that single name. The same rule applies to wildcards: *.yourcompany.com also includes the root domain.

Multiple domain names?

If you have several specific domain names, possibly including a wildcard, use a multi-domain (SAN) certificate. You can mix single names and wildcards in one certificate.

Need organisation validation (OV)?

Organisation data in the certificate, pre-validation or compliance requirements

OV certificates (Organisation Validation) display your organisation's name in the certificate details. With pre-validation, the CA approves your organisation in advance, you can then issue OV certificates instantly for up to 1 year.

OV supports single domain, wildcard and multi-domain.
