What Is a Single Domain SSL Certificate?

Single Domain SSL certificate

Single Domain SSL certificates or One Domain SSL certificates secure one fully qualified domain name (FQDN) or a subdomain under a single SSL installation; for example, with a Single-Domain cert, you can protect all the pages of

Some single-domain SSL certificates cover both the naked version ( and the “www” version of the domain name ( However, certain one-domain SSL certificates cover only the version that you provide in the Certificate Signing Request (CSR). For this reason, before purchasing a one-domain SSL certificate, read its specifications carefully so that it matches your website’s needs.

Single Domain certificates bring the latest encryption technologies to your site. The SHA 2 algorithm, coupled with an unbreakable certificate and key encryption (up to 256-bit and 2048-bit, respectively), offers the ultimate protection against cyber thieves. They are compatible with 99.3% of browsers, major server platforms, and email clients.

Available as Domain Validation (DV), Business Validation (BV), and Extended Validation (EV) certificates, Single Domain SSL products encrypt websites of any category and size. They are perfect for individuals and businesses with just one website.

Great selection of certificates with a clear definition of properties for each certificate makes it easy to choose the right one.

Easier and cheaper than going directly and ordering via the vendor, thank you for the information and the simple shopping experience.

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.

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.

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

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.

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.

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.

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.
