DV
Abbreviation for Domain Validated
In short and in plain language
DV means that a certificate comes with a check of the domain.
The issuer only checks that the person who asks for it controls the domain.
So the certificate holds no checked facts about the firm behind it. In most cases, such ones can be renewed on their own.
Definition
DV refers to checking the domain for SSL and TLS certificates: the certificate authority only verifies that the applicant controls the domain. Such certificates carry no verified details about the business behind them. They can usually be renewed automatically.
