What is Multi Domain SSL Certificate?
Multi domain SSL certificate is type of SSL certificates that allow to secure you multiple domains and sub domain with single certificate. You can add, edit, and delete the domain in the current certificate.

- www.myexample2.nz (SAN#3)
- autodiscover.domain1.myexample.net (SAN#4)
- domain. domain2.myexample.co.in (SAN#5)
SAN field allows additional fields where a user can input extra domains and subdomains in this certificate. The multi domain comes with domain, organization, and extended validation types. Except for domain validation, the rest validation types require thorough verification of business entities along with third-party resources. The certificate is also known as UCC (Unified Communication certificate) which is idyllic for Microsoft exchange and communication servers.

The multi domain also has an option of wildcard SSL that is called multi domain wildcard SSL certificate. This type of certificate is a combination of wildcard + SAN domains. Check the below example for a better understanding.
- www.example.com (common name)
- *. example.co.in (SAN)
- *.your.example.com (SAN)
- *.domain1.example.com (SAN)
The above different levels of wildcard domains and their respective subdomains can be secured with a multi domain wildcard SSL certificate. Many SSL providers offer to secure up to 250 extra SANs (depending upon the provider) in the same certificate. It is to note that multi domain wildcard can be of domain and organization validation type as wildcards cannot be combined with extended validation types.

Benefits of Multi Domain SSL Certificate
Different features of multi domain certificates make it worthy for e-commerce, the finance industry, large corporations, and other companies that carry different domains/subdomains.
Multi domain certificate saves the cost to be spent on individual domain certificates by covering all domains and subdomains in a single certificate. Moreover, you just need to reissue the current certificate to add a new domain to the certificate. Purchasing a separate SSL certificate for a domain or subdomain is a tiresome task. Instead, you can go with multi domain to secure all hostnames.
You can do reissues in case of adding domains. Reissues are free and can be done several times. Reissue of a certificate is helpful when you wish to operate a domain from a different server than a current one. If you have lost a private key, you need to reissue the current certificate. The reissue is a simple process where a new CSR generation and domain validation can do the main job.
SHA-2 and 2048-bit RSA encryption make the data transfer more secure between the client machine and the intended server. Cybercriminals will have a hard time breaking such strong encryption which makes it next to impossible task for them. The certificate uses the latest encryption standard prescribed by the NIST and the CAB Forum.
These certificates come with a site seal that can help motivate customers to deal with the website. The site seals are static and dynamic. A dynamic site seal shows the company’s verified information whereas a static seal is an image that shows the site is secured.
