More about SSL validation methods
  • D
    Certificates with domain validation
    To obtain this type of certificate you only have to confirm that you own the domain or that you are its authorized representative. It can be ordered by both individuals and legal entities. You will need to specify your Verification Email for confirmation. Typically, it is an adress from WhoIS or an address at the domnain that the certificate is issued. It must be a valid address, since that's where the Certification Center will send all the instructions and the certificate's code. By default, we use, where is the domain, for which the certificate is issued. Note, that if it contains any hints that the site is a bank, forex or any other institution that runs financial transactions, you will need a certificate with both domain and organization validation.
  • D+O
    Certificates with domain and organization validation
    When registering certificates for financial institutions, CC checks not only the domain name, but also its ownership. Any visitor of the website will see the name of the organization that owns it in the address bar.
    Before you apply for the certificate, make sure that your WhoIS info is valid and you are credited as the domain owner, not the CEO or system administrator. The process of verification will be considerably simplified if your organization is listed in the public databases on the Internet. Otherwise, you will have to send copies of your documents to the CC, in order to prove the existence and validity of your organization.
  • EV
    EV (Extended Validation)
    Extended Validation means that it is a certificate of the highest trust level possible, or, as they are called by the public, "a certificate with a green address bar". To obtain this certificate, you will need to pass additional checks, and in case with corporate clients, will have to send CC a special written form with the data on your organization, certified by a signature and a seal.
    Extended Validation informs your vustomers that the traffic between your website and the visitor is secure, and both your website and organization have passed all the checks.
    Here is the "green address bar" in different browsers: Green SSL string in browsers -

    SGS (Server Gated Cryptography)
    SGC certificates provide the highest level of connection encryption irrespectively of the type and version of the client browser.

  • MOB
    Mobile certificate
    Not all SSL certificates provide a secure connection when your visitors are using browsers on mobile devices (phones and tablets). Typically, such certificates are certificates with the initial domain check.
  • SAN
