Multi-domain SSL certificates are supported via SNI (Server Name Indication) on [[determining-platform-version]] platforms and newer.

## What is SNI?

[SNI](https://en.wikipedia.org/wiki/Server_Name_Indication) allows multiple domains to share a single certificate, protecting multiple websites on your account with one SSL certificate. SNI is compatible with all modern browsers.

## Requirements

To use a multi-domain certificate, purchase a multi-domain or "UCC" certificate from a trusted SSL certificate authority.
