A domain validation SSL certificate is available for all individuals, businesses, sole traders and private customers. There is no paperwork involved; you just have to provide validation by email.
We recommend to use domain validation SSL certificates for small websites and systems, when end-user’s trust is not a high priority task for you.

Domain validation (DV).This is the lowest level of authentication used to issue SSL certificates. The CA will issue a domain-validated certificate to anyone who is listed as the domain admin contact in the WHOIS record (the public record associated with each domain name) simply by sending an email to the contact email address. As a result, domain-validated certificates are issued very quickly, but no company information is checked or displayed on the certificate, making it easier for internet criminals to gain this type of certificate from irresponsible CAs.

Domain Validation SSL Certificates – Domain-validated certificates, work well for situations where trust and credibility are less important because the site is not customer facing, like an internal server, mail server or test and development servers. DV can also work in instances where there is no ambiguity about who owns the domain because your business is known by its domain name, like google.com.
