SAN Certificate - SSL certificate for your website
A SAN certificate is the same thing as Multi-Domain, just named after the Subject Alternative Name extension, where the list of names goes. At Leneex, you buy one certificate and list all the domains you need in it, and individual subdomains too if necessary. You can install it on your website, mail server, and control panel, and support will tell you how to configure each service. Instead of several purchases and renewals, you make one.

Four steps to your SAN Certificate for website
Write down all the domains and subdomains that should run over HTTPS. Check the limit on the product page.
Choose a plan and enter the names. It isn't always possible to add a VPS's IP address, so it's best to check this with support beforehand.
Each name goes through domain control validation. The certificate is issued once the whole list is confirmed.
Installing a SAN SSL certificate means connecting one file on the web server, the mail server, and the control panel. A new name is added later through a reissue in your account dashboard.

Technically, it's one type: a certificate with the Subject Alternative Name extension that lists several names.
The number of names is limited by the plan you choose, and extra ones can be purchased. Exact limits are listed on the product page.
Yes, the list can include both main domains and individual subdomains, for example example.com, shop.example.com.
Public certificate authorities don't issue certificates for public IP addresses in every case. Check the terms of the product you choose or ask Leneex support.
Through a reissue in your account dashboard: you add the name, validate it, and install the new certificate file on your server.
Our engineers will show you how to use one certificate for your site, mail, and control panel. Each service has to be configured separately.
Renewal is handled in your dashboard with the current set of names. Before that, check that you still need all of them.
Question 01
How does a SAN SSL certificate from Leneex differ from Multi-Domain?
Technically, it's one type: a certificate with the Subject Alternative Name extension that lists several names.
A regular certificate is tied to one domain. Want to protect example.com? You buy a separate certificate just for it. That sounds logical while you have one or two domains. But five? Ten? That's where a SAN certificate for a website comes in.
Why Do You Need a SAN SSL Certificate?
SAN stands for Subject Alternative Name. It's a field in the body of the certificate where the list of all the names it protects is entered; modern browsers check the SAN, not the Common Name. Technically, it's an extension of the X.509 standard, which all modern certificates are built on, not some exotic technology on the side.
How Does It Work?
In practice, it works like this: you get one certificate file and one private key, and inside that file is a list of several domain names, each of which the browser will treat as secure.
A user goes to example.com, and the certificate matches. They go to totally-different-domain.net, which is also on the list, and it matches too. The magic is that the domains don't have to be related to each other by name in any way.
What you can include in a SAN certificate's list of names:
Name type | Example | Notes |
|---|---|---|
Main domain | example.com | Listed as a separate name |
Subdomain | shop.example.com | Listed as a separate entry |
Domain in a different TLD | example.eu | Validated separately |
Independent domain | totally-different-domain.net | The name doesn't have to match the others in any way |
Wildcard name | *.example.com | Depends on the plan terms; check the product page |
IP address | 203.0.113.10 | Availability depends on the issuance terms; better to check with support |
SAN or Wildcard: What's the Difference
But users often mix up a SAN certificate with a wildcard certificate, and it's an understandable confusion, because both solve a similar problem (“I have a lot of things to protect”) in different ways.
Wildcard covers all first-level subdomains of one domain: *.example.com covers shop.example.com and blog.example.com, but not example.net. SAN works differently: names are listed explicitly, so one list can contain example.com, example.net, and shop.example.org. One domain with many subdomains is a case for Wildcard; several different domains, for SAN.
Available Validation Levels
SAN certificates come with domain validation (DV), organization validation (OV), and extended validation (EV). The basic SAN in the Leneex catalog is at the DV level: the authority only needs to confirm that you control all the names on the list. If the certificate details must show a company, choose OV Multi-Domain or EV Multi-Domain. Encryption is the same across all levels.
How to Build Your List of Names
Before you buy a SAN SSL certificate, write down all the addresses that should work over HTTPS. If your site is available both with and without www, check on the product page whether the second version is included automatically. Don't add names “just in case”: each one has to be validated, and any change to the list means a reissue. The base package includes three names, and additional ones can be purchased.
What to Consider When Installing
The certificate, private key, and intermediate certificate chain are installed the same way as for a single domain. If your services run on different servers, you'll have to copy the same key: transfer it only over a secure channel and restrict access to it. If it leaks, the certificate is reissued and the old one is revoked.
Also note: the names in a certificate end up in public Certificate Transparency logs. It's better not to put addresses you don't want outsiders to know about on the list.
Validity Period
The maximum validity period of public certificates is capped by industry rules and is gradually getting shorter: it's currently 200 days, and from March 2027 it will be 100. So keep track of your renewal dates well in advance.
Choose SAN when you need to bring several independent domains under one protection. For one domain with subdomains, Wildcard is a better fit, and for a single site with no subdomains, a standard certificate. The current price of a SAN SSL certificate is listed on the product page.
