SSL Certificates protect user data and defend against identity theft. If you are asking for personal information or accepting payments, have shopping carts or custom forms with sensitive data you need to have SSL enabled on those pages. Many customers will not conduct business without the HTTPS/SSL lock on pages asking for customer data.
Our SSL certificates are backed by Comodo and offer SHA-2/2048 bit encryption. The certificates we issue are supported by all popular web browsers and are supported by most popular applications with no trouble. You might also notice higher web rankings in search engines on HTTPS encrypted websites as Google is now favoring secure sites and gives them a higher priority!
