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.
Major search engines also started giving sites that are SSL secured higher ranking in search results. Modern web browsers will also alert customers/visitors if your site is not using SSL. 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.
