What are different types of SSL?
Extended Validation (EV) SSL Certificates:
where the Certificate Authority (CA) checks the right of the applicant to use a specific domain name PLUS it conducts a THOROUGH vetting of the organisation. The issuance process of EV SSL Certificates
is strictly defined in the EV Guidelines, as formally ratified by the CA/Browser forum in 2007, that specify all the steps required for a CA before issuing a certificate, and includes:
- Verifying the legal, physical and operational existence of the entity
- Verifying that the identity of the entity matches official records
- Verifying that the entity has exclusive right to use the domain specified in the EV SSL Certificate
- Verifying that the entity has properly authorised the issuance of the EV SSL Certificate
EV SSL Certificates are available for all types of businesses, including government entities and both incorporated and unincorporated businesses. A second set of guidelines, the EV Audit Guidelines, specify the criteria under which a CA needs to be successfully audited before issuing EV SSL Certificates. The audits are repeated yearly to ensure the integrity of the issuance process.
Organisation Validation (OV) SSL Certificates:
where the CA checks the right of the applicant to use a specific domain name PLUS it conducts some vetting of the organisation. Additional vetted company information is displayed to customers when clicking on the Secure Site Seal, giving enhanced visibility in who is behind the site and associated enhanced trust.
Domain Validation (DV) SSL Certificates:
where the CA checks the right of the applicant to use a specific domain name. No company identity information is vetted and no information is displayed other than encryption information within the Secure Site Seal.
