- Domain Validation (DV) - For a DV SSL, the only thing that's checked is that the person requesting the SSL certificate has control over the domain that the SSL is being issued to. This validation is done by sending a confirmation email to a specific address, or by checking for the presence of a specific file on the website. The entire process is almost always fully automated.
- Organization Validated (OV) - For OV SSL, an actual human almost always checks your business records with those from a reliable source, like state or other government records. During the order process, you will be asked for things like your business tax ID number or other official documents so that they can be verified.
- Extended Validation (EV) - EV SSL are the most stringently checked SSL certificates that we have currently. Not only are your government records checked, but other aspects of your business are also verified. This kind of certificate usually produces a green color in your browser's address bar - helping your visitors know that your site is secure.
