The Multiple Domain Wildcard SSL Certificate secures an infinite number of sub-domains under multiple domains, is one of the most special certificates in the SSL industry. To businesses with many domain names on the same server, the Multidomain Wildcard SSL certificate allows you to encrypt any domain name or common name and all its sub domains with only one certificate. This is an excellent choice. As a cost-effective option, a Multi-Domain Wildcard SSL helps simplify security management through the aggregation of sub-domains on a single certification.

A Multiple Domain Wildcard SSL is available with two types of validation: organization validation and domain validation. The installation is very cost effective and easy. Generally, the validation can be done in just a few minutes.

The process for creating a Multi-Domain Wildcard Certificate is simple. Depending on the vendor purchased from (I would recommend to check out https://thesslonline.com to know pricing), one Multi-Domain Wildcard Certificate will protect up to 250 domains. No matter which provider, a rule must be followed to obtain a certificate: the CSR must have a non-wildcard domain for the multi-domain wildcard to act as the common name. You may add additional domains or SANs.
