If you\u2019re here because you\u2019re wondering \u201cwhat is a multi domain SSL certificate?\u201d or \u201cwhat is a UC multi domain certificate?\u201d then you\u2019ve come to the right place. A multi domain SSL certificate is also known as a subject alternative name (SAN) or unified communication certificate (UCC). As the name suggests, it\u2019s used to secure multiple domains with a single certificate. Considering that many businesses have multiple domains, it makes sense to have a solution for business owners who have multiple websites. Would you rather manage multiple certificates for all your sites? Remember that it would involve installing each of them separately, keeping track of when to renew them, filling out individual certificate signing requests (CSR), etc. <\/p>\n\n\n\n

This can be tedious. If you have numerous websites, wouldn\u2019t it be more effective to manage and maintain all of them using one certificate? This is where multi domain UCC (SAN) SSL certificates can come in handy.<\/p>\n\n\n\n

What Is a Multi Domain SSL Certificate & How Does It Work?<\/strong><\/h2>\n\n\n\n

A multi domain SSL certificate is a single\ncertificate that covers multiple domains on a single IP. When it comes to the\nstrength of encryption, a SAN or a UCC multi domain certificate uses the same\nencryption standards as the rest of the solutions offered by any trusted\nthird-party certificate authority (CA). The difference lies in the SAN\nextension that\u2019s used to specify the additional domains. <\/p>\n\n\n\n

The base domain gets listed as the common name. It\u2019s supported on 99.9% of all web browsers and available for every level of validation \u2014 domain validation (DV), organization validation (OV), and extended validation (EV). SAN SSL certificates can secure up to 250 domains, subdomains, external IP addresses or hostnames on a single certificate. Larger certificates, with more SANs listed, might affect page load speeds by a few milliseconds.<\/p>\n\n\n\n
