Domain Validated SSL Certificate –  This is commonly referred to as a “low assurance certificate,” and is the most standard type of certificate. A webmaster should confirm through email or configure a DNS record for the certificate to be validated.

Organization Validated Certificate – Also known as a “high assurance certificate,” an agent needs to validate the domain ownership as well as organization info such as the name, city, state and country.
