What is Multi-Domain UCC/SAN SSL Certificate?
A UCC/SAN SSL Certificate (Unified Communications Certificate / Subject Alternative Name) allows you to protect multiple domains under one certificate. With this flexibility, you can secure different FQDNs and (in supported cases) even Wildcard entries without the need for separate SSLs.
Who is it for?
👨💻 Businesses managing multiple domain names
👨💻 Companies using corporate email or communication systems (e.g., Microsoft Exchange, Office 365)
👨💻 Organizations running multiple brand or product websites
👨💻 Enterprises seeking simplified domain portfolio management
Business Impact
UCC/SAN SSL helps organizations achieve time and cost savings by simplifying management across multiple domains. With one certificate, you can secure dozens of sites, reduce administrative complexity, and scale with ease. This makes it the ideal solution for enterprises that prioritize both security and operational efficiency.
➡️ One certificate, multiple domains – Secure sites like www.site1.com, www.site2.com, and mail.site3.com under a single UCC/SAN SSL.
➡️ Operational flexibility – Unlimited server installations, free reissues, and rekeys for effortless management.
➡️ Cost efficiency – Save money by consolidating several domains into one SSL certificate instead of purchasing multiple.
➡️ Professional credibility – Demonstrates a trustworthy image for companies operating across multiple domains.
