These encryption-only certificates are popular because of how fast and simple they are to get. All you have to do is prove you own the domain you wish to secure in order to get a DV certificate issued. This process usually takes just a few minutes to complete. You’ll get industry-standard encryption and trust indicators like HTTPS and the padlock icon. Internal testing domains, blogs, and basic template sites are good candidates for DV certificates since they offer full encryption but just basic trust indicators.
