Multi-Domain SSL Certificates Benefits

Multi-domain SSL certificates offer various security and marketing features to take your websites to the next level.

Effortless SSL Management

Managing the web security of multiple websites can be daunting. Multi-domain certificates simplify this task to almost automation. A single multi-domain product will smoothly encrypt up to 250 domains and sometimes unlimited subdomains.

Incredible Value for Money

A cheap multi-domain SSL certificate offers the same level of encryption as the premium ones. Security wise, you get the latest algorithms in the industry, impossible to crack by even the brightest hackers.

Industry-Standard Encryption

All multi-domain SSL certificates adhere to strict security protocols and regulations. The advanced SHA-2 algorithm and the unbreakable key and certificate encryptions offer the ultimate protection for sensitive data.

Extra Features for Customer Trust

All multi-domain SSL certificates come with static or dynamic site seals. You can display them anywhere on your sites to improve customer trust. SSL site seals are a strong indicator of your safety standards and credibility.

Frequently Asked Questions

What is a Multi-Domain (SAN) SSL Certificate?

Multi-Domain SSL Certificates are the most versatile SSL solution on the market. With a single Multi-Domain certificate, you can secure up to 250 different domains. Certain Multi-Domain products also protect unlimited subdomains, solving the most complex web security challenges.

Their flexibility saves users valuable time and tons of money. Instead of spending a fortune on separate certificates for each of your domain names, you can buy a Multi-Domain SSL certificate and quickly encrypt the entire network of your sites.

What is SAN SSL and UCC SSL?

When you buy a Multi-Domain SSL certificate, please note that it has two alternative names: SAN SSL and UCC SSL. SAN SSL stands for Subject Alternative Name Certificate, and UCC SSL is an acronym for Unified Communication Certificate. You will find all these names across our wide range of Multi-Domain products.

How Does Multi-Domain SSL Work?

Multi-Domain SSL certificates work the same way as Single-Domain certificates, except for the number of domains they can secure. A multi-domain cert protects both your internal and external domains/subdomains under a single SSL installation and a one-time renewal period. Depending on the SSL brand you choose, the certificate will include a few additional domains by default (called SANs), as well as the option to secure multiple subdomains. If you need more domains, you can add up to 250 SANs. But that’s not all. Even if your multi-domain certificate is up and running, you can always purchase extra domains and then simply reissue your certificate.

For instance, with a Multi-Domain SSL cert that includes 3 domains by default you can secure:

Three different domains:


Three different subdomains:


Three different domains and subdomains:


Configuring your Multi-Domain certificate is easy. During the CSR (Certificate Signing Request) generation, please include your first domain. For example, Right under the CSR text area, in the additional domains’ fields (SANs), specify the rest of domains or subdomains you want to encrypt. After you pass the SSL validation, you can safely install the certificate on your server.

How many domains can be protected by a SAN certificate?

A SAN certificate can encrypt 1 to 3 domains by default, depending on the certificate brand, and up to 250 additional SANs for an extra fee. You can request more SANs during your SSL certificate order at the checkout.

Copy Link

What is the Subject Alternative Name field?

The Subject Alternative Name field is where you include additional hostnames (sites, subdomains, common names, etc.) to be encrypted by a single Multi-Domain SAN SSL certificate.

What is the difference between a SAN certificate and a Wildcard certificate?

A SAN certificate secures multiple domain names under a single SSL installation, while a Wildcard certificate protects unlimited subdomains and the domain name. SAN certificates can also encrypt subdomains, but a Wildcard certificate cannot secure multiple websites.

Excellent customer service when I ordered the wrong cert! The support team then helped me get the correct cert and refunded me on the incorrect cert I bought! Very fast and a happy customer.

June 23, 2020

One of the most reliable SSL brands. If you need to secure subdomains and can afford it, don’t think twice. Get it.

June 12, 2020

The price seems fair for an EV certificate, especially the two-year deal. Unlike my previous provider, which I won’t advertise here, at SSL Dragon, the buying steps are easier and better explained.

May 31, 2020

Always a pleasure doing business with SSL Dragon. Thawte certificates consistently deliver the highest encryption and customer trust.

May 16, 2020

Was assigned to secure several NGO sites. Picked this certificate because of a higher warranty and reasonable price. It’s always a pleasure to work with SSL Dragon.

December 17, 2019

Simply the best. Easy to buy and configure. Plenty of features. Can display the site seal in different languages as well.

A top-class product from a reputable company. Credits to SSL Dragon as well, for a smooth buying experience and excellent price.

May 3, 2019

This is the third SSL Certificate I buy from SSL Dragon, and the first one from GeoTrust. All I can say is the certs work as described in the specs, and the support is very friendly.

March 24, 2019

The SSL wizard recommended this certificate for our e-stores. We’re already on the third renewal, and during all these years, didn’t have a single issue with it.
