The awarding of a certificate is bound to various criteria, for example, the applicant must be able to prove that he is the owner of the corresponding domain or that he has a corresponding right of use. We distinguish between:


Domain Validation (DV)

Domain Validation is the simplest type of SSL certification. This certificate variant provides confirmation that the domain has been registered and that the certificate request has been approved by a person with administrative powers.


Validated information:

  • Domain Control


Organisation Validation (OV)

This variant fulfils more validation requirements compared to the Domain Validation certificate. The Organization Validation certificate authenticates domain ownership as well as the company information (name, city and country) contained in the certificate.


Validated information:

  • Domain Control
  • Authentication of the respective company/organisation as legitimate


Extended Validation (EV)

EV represents the highest authentication standard. The validation criteria are defined by the CA/Browser Forum and audited annually by KPMG. EV triggers the green address bar on the web browser and displays the company name and certification authority.


Validated information:

  • Domain control
  • Authentication of the respective company/organisation as legitimate
  • Request authorisation of the certificate requester
