The type of domain or domains you’re trying to secure will determine if you need an EV, OV, or DV certificate.
Domain Validation SSL Certificates
DVs provide the fastest and cheapest way to secure a website. The validation process includes only one step, which is showing proof of domain name ownership. The simple process means this type of SSL certificate can be issued in minutes. This type works best for domains that don’t need to establish site visitor trust. DV certificates work well for internal sites, test servers, and test domains.
Organization Validation SSL Certificates
This type of certificate provides the same level of protection as a DV certificate but shows that the individual or organization has been validated by a CA. To obtain an OV certificate, proof of domain ownership must be provided and a CA must confirm the legitimacy of the business or organization associated with the domain. Company name, address, and other details must be confirmed before issuance is completed. An OV SSL works for public-facing websites but is not recommended for those requesting sensitive information.
Extended Validation SSL Certificates
EV certificates provide the highest level of trust due to the strict validation process that must be completed before issuance. Once company details are confirmed, a human specialist will perform the last steps in the vetting process. This is the preferred SSL type for websites that request personal information and is the industry standard for eCommerce websites.
