Domain Validation (DV) Multi-Domain SSL Certificates secure multiple domains and subdomains. With just a one-time installation and renewal period, Multi-Domain DV certificates are the most cost-efficient SSL products on the market. They simplify the SSL management of your entire network of sites, requiring your involvement only twice: during the first setup and at the certificate renewal. You can spend the rest of the time improving your online projects, all while the Multi-Domain Certificate seamlessly protects them from cyber-thieves.
What is Domain Validation?
Unlike BV and EV multi-domain certificates, DV multi-domain products don’t require any paperwork whatsoever. Both individuals and companies can get a DV multi-domain cert within minutes. That’s Domain Validation in a nutshell: straightforward application, and instant approval.
All you have to do is prove domain ownership and submit a valid email (e.g., [email protected]) to your Certificate Authority. If your CSR (Certificate Signing Request) doesn’t have typos or spelling mistakes, expect to receive your certificate in just 5 minutes.
DV Multi-Domain certificates don’t offer the highest level of customer trust, but they excel in other areas. Besides being incredibly cheap, these flexible SSL products deliver the same advanced encryption as any other certificate, be it BV or EV.
Whether you need to protect a couple of your blogs or dozens of heavy websites, a DV Multi-Domain certificate has got you covered. It helps solo entrepreneurs, small businesses, startups, and NGOs streamline the SSL management across a large number of sites.
How DV Multi-Domain SSL Certificates work?
DV Multi-Domain SSL Certificates secure both your internal and external domains/subdomains under a single SSL installation and a one-time renewal period. To get a Domain Validation cert, you need to prove to the CA that you are the owner of the website you want to encrypt. With no documents and company information needed, filling in your CSR request is easy.
Depending on the SSL brand or product you pick, your DV Multi-Domain SSL certificate will include up to 4 additional domains by default (called SANs). If you need more domains, you can always buy additional SANs on the checkout page. For instance, with a Sectigo PositiveSSL Multi-Domain SSL Certificate, you can secure four domains by default and a maximum of 250 SANs on request.
Let’s say that you want to protect just four domains; here’s what you can secure:
Four different domains:
Four different subdomains:
Four different domains and subdomains:
To configure your DV Multi-Domain certificate, you must submit the following info about your domain in the CSR.
- The FQDN (Fully Qualified Domain Name). For example, yoursite.com
- A valid email address
During the CSR (Certificate Signing Request) generation, please type your first domain to which you want to assign the Multi-Domain cert. For instance, yoursite.com. Right under the CSR text area, in the additional domains’ fields (SANs), add the rest of domains or subdomains you want to secure. After your CA signs and sends the SSL certificate files to your inbox, you can continue with the installation.
Important! Sectigo also offers a one of a kind DV Multi-Domain Certificate that can secure unlimited subdomains along with multiple domains. If you buy the Sectigo PositiveSSL Multi-Domain (UCC/SAN) Wildcard SSL certificate, here’s what you need to remember:
When you add a SAN item such as *.yoursite.com, you secure its unlimited subdomains, but not the domain itself. To protect all your domains and subdomains, you’ll have to configure the Multi-Domain Wildcard SSL cert as follows:
- yoursite.com (specified in your CSR)
- *.yoursite.com (for all subdomains)
- *.yoursecondsite.com (for all subdomains)
A Multi-Domain Wildcard cert allows you to protect second-level subdomains as well. For instance:
- yoursite.com (specified in your CSR)
Multi-Domain Wildcard SSL certificates allow you to add as many subdomains as you want, whenever you need, without reissuing your Wildcard cert each time you assign a new subdomain.
