There are several types of SSL certificates, First,certificates are divided into three groups according to the type of how the site will be checked:

A Domain Validated SSL Certificate (DV) validates the domain and encrypts and protects data in transit using the https protocol. Both individuals and organizations can install it on their website. It is produced, as a rule, very quickly – definitely no longer than three hours. After the certificate is issued and installed, a lock icon appears on the site and the page becomes secure.

The second type is OV SSL Certificates. Its main difference is that in addition to protecting information on the site, it confirms the ownership of the domain of a particular company. The certificate is issued only to companies with a confirmed phone number and legal address, On a site with such a certificate, the user can find information about the organization that owns the site by opening the certificate data. This type of SSL is usually issued within three days.

An Extended Validation SSL Certificate(EV) is essentially the same as an OV certificate. The main difference is that when you click on the lock, the name of the company appears. The fact is that the organization checks in detail both the tax and commercial activities of the company. EV SSL is issued usually within 5 days.

Secondly, they can differ in the number of domains and subdomains that will be protected. SSL certificates differ in the type of protection. There are three types of certificates in this category:

For one domain – the certificate will protect the main domain or any subdomain. This SSL is suitable if customers enter personal data on one page of the site. For example, such a certificate is suitable for a personal website, blog or promo page.

For several domains of the same company. The certificate is suitable for companies with mirror sites in other domain zones. Or, for example, for sites with contests and promotions that are hosted on a separate domain.
For subdomains. This SSL will simultaneously protect the main domain and all subdomains to which it is issued, for example, release the * webdev101.xyz or * .sub.webdev101.xyz domains. This type is suitable for a site that has sections on subdomains, for example, sites on which you can create personal accounts – online stores or banks.
All of these types of certificates encrypt traffic between the site and the browser. In addition, they have additional options that we mentioned above:

WildCardWildCard Protects the connection to the domain and all its subdomains.
SAN – Protects domains according to the list specified when obtaining an SSL certificate.
