SSL certificates protect websites of all types and sizes, but what if you have multiple domains that need protection? Can you protect them all with a single certificate? The answer is a resounding yes. All you need to do is get an SSL certificate with multiple domains. But this is where things can get a bit tricky.

Multi-domain certificates are also known as SAN or UCC certificates, and all these names can be confusing for new users. Our visitors often ask us: “ What is a UCC certificate? ” That’s why we wrote this article about UCC certificates, so that everyone understands what they are and how they work.

What is a UCC certificate?
A UCC (Unified Communications Certificate) is a digital mobile app development service certificate designed to secure multiple domain names or subdomains under a single certificate. It provides security for websites, email servers, and other online services by ensuring encrypted communication between clients and servers. UCC SSL certificates are typically used by individuals and organizations that manage multiple domains or subdomains on a single server or across multiple servers.




Why should you use a UCC SSL certificate?
A Unified Communication certificate allows you to secure multiple domain names or subdomains within a single SSL installation. As a result, you can secure multiple websites or online services without requiring separate certificates for each, saving you time and effort in managing your security system.

What's more, instead of purchasing separate certificates for each domain, which can increase costs, a standard UCC SSL certificate covers multiple domains, providing a more cost-effective solution for protecting your online assets.

Overall, UCC SSL certificates make it easier to manage your security infrastructure. With just one certificate to manage, you can simplify renewal, installation, and monitoring, reducing your administrative burden.

How does a UCC certificate work?
A UCC SSL certificate encrypts data transmitted between a user's browser and a web server.
Here's how it works:

Certification Authority (CA) : The process begins with a Certification Authority , a trusted organization that issues digital certificates. When you request a UC certificate, the CA verifies your ownership of the domains you want to secure.
Protect multiple domains : After verification, the CA issues a single UCC SSL certificate that includes all the domain names you provided during the application process. This way, you can protect multiple domains or subdomains with just one certificate.
Encryption and Communication : Once installed, a UCC SSL certificate encrypts data transmitted between the user's browser and your web server using the Transport Layer Security (TLS) protocol. Depending on the number of Subject Alternative Names (SANs) enabled, it secures multiple websites or subdomains under a single certificate, protecting information in transit from cyber thieves.
