Domain Validated (DV) Certificates
DV certificates are extremely basic and they can only secure server-browser communication. You can obtain them within a few minutes by simply verifying that you own the domain that you’re purchasing the SSL certificate for. DV Certificates are suitable for websites wherein users don’t have to login or provide any personal information.
Organization Validated (OV) Certificates
OV certificates are a step above domain validated certificates. They secure server-browser communication in addition to providing some organization/business validation. In order to get these certificates, you also have to prove that your website’s business is legitimate. Organization Validated Certificates are suitable for those who have a legitimate business, whose website collects sensitive information from their users, but those who don’t want the additional expense of an EV certificate.
Extended Validation (EV) Certificates
EV certificates are the most trustworthy of all certificates. They are also extremely expensive and it takes several days or even weeks to get them issued. In order to receive them, the Certificate Authority (CA) conducts a thorough examination of the website’s business to make sure it is legitimate and safe. They also verify that the identity of the organization matches the official records and that they have the right to use the specified domain.EV certificates are most suitable for e-commerce websites. If you require users to enter their payment details and address, you should get an EV certificate.
Standard Certificates (Single domain)
This is the most basic package. It secures a single fully qualified domain name (FQDN) with no additional subdomains. For example, it can only secure .website.com, nothing else.It is most suitable for website owners with a single website and no subdomains within that website.
Wildcard Certificates
Wildcard SSL Certificates can simultaneously secure multiple subdomains within a single FQDN. For example, if you have a domain called .website.com, it can also secure login.website.com and payment.website.com.
In order to secure the various subdomains, you have to add an asterisk (*) before the primary domain name. For example, you have to enter *.website.com when purchasing the certificate.
It is most suitable for website owners with a single primary domain but various subsets and subdomains within that.
Multi-Domain/SAN/UCC Certificates
Multi Domain Certificates are also known as Subject Alternative Name Certificates and Unified Communication Certificate.
They can simultaneously secure multiple up to 100 FQDNs along with all their subdomains. For example, it can secure .website.com, .website.org, .browser.com, .browser.org, and all of their subdomains. These are most suitable for large businesses and organizations with several websites, all with their own set of subdomains.
