DV

What is DV?

DV stands for Domain Validated. It is a type of SSL certificate that verifies the domain owner's identity through email or DNS checks. This validation process ensures that the certificate is issued to a legitimate domain owner, providing basic encryption for website traffic.

How DV Works

DV certificates are issued by Certificate Authorities (CAs) like DigiCert. The validation process involves checking the domain's ownership through email verification or DNS records. Once validated, the CA issues the certificate, which encrypts data between the user's browser and the server. This process is quick and automated, making DV certificates a popular choice for websites that need basic security.

Example

For instance, a website with the domain example.com can obtain a DV certificate by verifying ownership via an email sent to [email protected] or by adding a DNS record to the domain's DNS settings. Once verified, the certificate is issued, and the website can use HTTPS to secure data transmission.

When You Use It / When You Don't

Use DV certificates for websites that require basic security, such as blogs or small business sites. Avoid DV certificates for e-commerce sites or any platform handling sensitive information, as they do not verify the organization's identity, which could affect user trust.
