Over the past 3 years, the number of SAN certificates has doubl. SAN is an option that allows you to save on SSL and protect several domains and subdomains at once. We tell you what its advantages are and in what cases it is worth connecting.
What is an SSL certificate with SAN option
An SSL (Secure Sockets Layer) certificate is a special code that allows a browser to establish a secure HTTPS connection protocol. Sites with this certificate receive a lock as a sign that they protect the transfer of data (including confidential data) from theft – by clicking on the icon, you can see who issu the SSL and to whom. We talk in more detail about how digital protocols work in the article ” All about SSL in simple terms “.
How to find out who issu the SSL certificate to a website
A regular SSL works on the principle: “1 certificate = 1 site”. But large companies most often register several domains for different purposes. In this case, the SAN option is suitable – with it, you can order 1 certificate for all available domains. This solution saves budget and time – it is easier to manage one certificate.
SSL with the SAN (Subject Alternative Names) option is a certificate that can be connect to several domains and subdomains. It is also call multi-domain. Let’s say a company owns the names:
USA phone number data is a list of all contact usa phone number data names and addresses in the USA as well as consumer or professional phone numbers. USA phone number data is used to inform customers about their products or services. Hundreds of business applications are made possible with USA phone number data.
mysite.ru,
mail.mysite.ru,
my-company.site,
my-company.ru.
Without a SAN, you would have to buy a certificate every year for each name, but with the multi-domain option, one is enough.

As a result, digital signatures with SAN have become twice as popular in the last few years. According to a study by Reg.ru and the GlobalSign certification center, more than 1 million SSLs were us in the .ru zone in 2020, of which only 80 thousand were with SAN. Today, according to StatOnline.ru , the number of multi-domain certificates, which account for 2 to 500 domain names, has reach 154 thousand. At the same time, the “1 certificate for 1 domain” format remains the most popular – more than 1.6 million such signatures have been issu in the .ru zone.

Types of SAN certificates
There are 3 types of multi-domain certificates:
SAN Subdomain — protects only one domain and its subdomains of any level that were specifi when ordering. For example, mysite.ru and mia.mysite.ru, blog.mia.mysite.ru;
SAN FQDN — protects the main and additional domains. For example, you can connect mysite.ru, mysite.com, мойсайт.рф to it;
SAN FQDN + Wildcard – protects primary, additional domains and their direct subdomains.
When is a SAN certificate ne?
Multi-domain digital signature is beneficial for large companies and those who use more than 1 domain for different purposes.
Different domain names for one site. For example, if for some reason the site decid to change the domain – a more concise name became available or the company did a rebranding. So that users can still find the resource using the old link, the secondary domain is left and a rirect to the main one is set up. This is what the Montreal molecular micine laboratory did – two names are register to it: biomarker.bio and benoitcoulombe.ca (the main one).

In Reg.ru the SAN option works for 3 types of certificates:
DomainSSL is an entry-level certificate with DV domain validation. This means that the digital code confirms the ownership of the domain. DomainSSL provides encryption of transmitt data, but does not confirm the existence of the organization. With the SAN option, the certificate can be connect for the main domain and alternative subdomains of any level.
