Certain pages on our site that carry sensitive information are encrypted (the data send between your computer and our server is encoded so that anyone that intercepts the data will not be able to understand it). Web page address that start with https:// are encrypted (normal pages start with http:// - see this one).
The security certificate that encrypt these pages can be self signed (created by ourselves) or they can be signed by an Certificate Authority (which costs money). We have used a self signed security certificate, which means you may receive a warning from your browser telling you that this certificate may not be from who you think it is - Don't worry. The page is still encrypted, it is just that we want to spend our money on things that genuinly help our customers. If you are concerned please give us a call.
