Domain Validation (DV)
RaipdSSL and Comodo Essential
This is the cheapest form for a SSL certificate for your domain name. Perfect for situations were you want to encrypted usernames and passwords, and for general e-commerce stores to accept credit card payments.
The Certificate Authority (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 which is why these certificates are available in a short period of time as only an email address is required to prove you own the domain name.
Organisation Validation (OV)
True BusinessID and Essential Wildcard
(Also called Company Validation)
The next step up. The Certificate Authority (CA) checks the right of the applicant to use a specific domain name PLUS it conducts some vetting of the organisation, so in addition to verifying the email address, additional documentation must be provided to certify your company’s identity.
A Wildcard SSL Certificate enables SSL encryption on unlimited subdomains using a single certificate. The subdomains must have the same second level domain name (i.e. domain.com).
Extended Validation (EV)
True Business ID with EV
This is 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
This is why they’re is up to a 10 day provisioning time for EV SSL Certificates as there are quite a few requirements for obtaining an EV based SSL certificate.
