One of our corporate clients owns huge number of domains and they want to secure all of them. What options are there for a large number of Domains (say 500) to run under one SSL Certificate?


You may need Multi-Domain SSL certificate to cover large number of domains under one SSL certificate. Multi-Domain SSL is also known as SAN SSL certificate and sometime also known as Cloud SSL. The maximum 200 numbers of domains you can secure under one SAN SSL.

SAN SSL is the best solution for hosting providers who host large number of domains for customers and all they need SSL security for their website. Main advantage of multi-domain SSL is you just need a single IP address to setup SSL website hosting.

Other advantage is you can add new domain names on-the-fly. You can add new domains and replace old names in SSL reissue process. You just need to replace the SSL certificate on server and all domains will be covered in single SSL certificate.


Every domain name included in this SAN SSL requires fulfilling domain verification process. Applicant will have to prove that he is authorized to acquire SSL certificate for the applied domain. Please contact our support team to know more about SAN SSL verification and pricing.

Does Azure support multi-domain SSL certificate and setup?

Multi domain SSL works same on all platforms like ordinary IIS or apache installation. You just need to bind or configure each domain in Azure to use the same SSL certificate. No need to create multiple copies of SSL certificate or key files. You have to upload some certificates to the Azure management portal and define them in the config files. You’re good to go!
