Frequently Asked Questions

What is an SSL Certificate?

An SSL Certificate is a digital certificate issued for a domain by a central authority called the Certificate Authority. To be issued an SSL Certificate, you must purchase one and then go through a verification process conducted by the Certificate Authority.

An SSL Certificate encrypts information sent from your user’s browser to your website and authenticates your website’s identity. This protects your customers and increases their trust in your online business — especially important if your site requires login credentials or handles credit card details.
SSL Certificates are compatible with all major browsers.

We don’t currently support upgrades or downgrades. If required you can purchase a new certificate and install it on the same web server as the old certificate.

While it isn’t difficult to install an SSL Certificate, it does involve following a series of steps. You can find more information in our KnowledgeBase.
