As the backbone of web security, Secure Sockets Layer (SSL) is a must for securing sensitive data passing over the internet — whether that’s e-commerce traffic, remote access to internal servers, or other secure communications.
Usually, one SSL certificate secures just one domain name or URL; however, some common situations are better handled with a type of certificate that allows multiple domains to be secured with just one certificate. You may have heard these multiple domain certificates referred to as subject alternative name (SAN) certificates or unified communications certificates (UCC). Depending upon your organization’s needs, these types of certificates can save you considerable time and money compared with buying and managing many individual certificates.
In this guide, you’ll learn more about typical situations where multiple domain certificates are the ideal solution. We’ll also explain how multiple domain certificates work and how to select the right multi-domain certificate for your needs.
