Frequently Asked Questions on Multi-Domain SSL Certificates

Can an SSL certificate be used on multiple domains?

Yes, it can be used on multiple domains. It is very easy to use an SSL certificate on multiple domains because the process is just a simple extension of your current hosting plan. You can have up to two domain names with an SSL certificate which you will be able to activate for free for each domain name separately.

Do I need multiple SSL certificates?

Yes, because it will safeguard multiple sites using the same IP address. Multiple sites mean multiple domains. You must generate multiple SSL certificates to protect multiple domains on the same IP address, especially if they are on the same server. If you want to protect your website from hackers, you should have at least two SSL certificates.

What is a multi-domain SSL certificate?

It is an SSL certificate that can be used for more than one domain name. This is an ideal solution for web admins looking to secure multiple domain names on one server. You can browse multiple domains with a single IP address, which is more efficient. On the other hand, you will be able to secure your website with a trustworthy SSL certificate.

What is a positive SSL multi-domain?

A positive SSL multi-domain is a domain name that has been purchased from another domain owner and was not created by the original owner. It is a great way to add authority to your website. The advantage of having a positive SSL multi-domain is that it allows you to have multiple domains, with each one pointing to a different site or page on your website.

Are SSL certificates tied to IP addresses?

Yes, an SSL certificate is tied to an IP address. A domain name that ends with "com" or "net" is considered to be associated with the Internet Protocol (IP) address of the server from which it originates. In this way, any website's visitors can verify whether or not they are communicating with a trusted site by verifying its domain name and IP address pair.

How can I use a multi-domain SSL certificate on my website?

You should use a multi-domain SSL certificate on every page of your site, including your home page and all subpages. A multi-domain SSL certificate can be used on one domain name or across multiple domains. If you are using a CMS, a server, or any other web application, it comes with two separate certificates when you purchase the certificate. The first one will allow an individual domain to use, and the second one unlocks your ability to run the same application on another subdomain within your organization or company. It is advisable to have at least one uniform naming standard for all domains in the certificate for easier management and installation instead of managing each separately.

Does a multi-domain certificate work with other HTTPS protocol sites?

The purpose of multi-domain certificates is to cover multiple domain names on one SSL certificate. A multi-domain certificate will work with other HTTPS sites as long as it's being used to secure the encryption with SSL in the same manner. So it can be bound to any number of domains on the same server to cover all HTTPS sites under one security blanket. By default, the HTTPS protocol protects HTTP traffic in case of a man-in-the-middle attack and not for website authentication. This is because a proper domain certificate doesn't guarantee the identity of the website. Instead, it only ensures that it has access to specific cryptographic keys to sign its encrypted traffic with so that the certificate will be trusted as genuine by your browser.

Are there any security risks of using SSL for multiple domains?

SSL Certificates are designed to work with multiple domains and do not create any security problems. Because SSL is still a certificate, if one of the domains is being used and suddenly gets hacked, that domain might be taken over for a low price by malicious third parties who would then own a certificate that was supposed to give enhanced security.

How does domain validation work for multi-domain SSL certificate order verification?

Domain validation is the process by which a certification authority provides reasonable assurance that a person, device, or organization controls one or more domain names. A Domain Validation (DV) certificate can be issued when the Regional Internet Registry (RIR) verifies contact details about the user, including address or phone number. Certificate validation can occur locally on the browser or on a third-party server that is said to be trusted by the server. This trusted server is the certification authority to verify with the organization that issued the certificate's cryptographic key before issuing it. Certification authority does not serve its customers directly and will delegate domain validation and other tasks verification through an accredited RIR operator.
