SSL (Secure Socket Layer) Certificate – Set-up by RWD. Having a https: URL creates an encrypted connection between your web server and your visitors’ web browser allowing for private information to be transmitted. This shows a potential customer that their e-commerce processing will be secure and protected. Each business purchases a certificate through Thawte, VeriSign, GoDaddy, SSL.com , etc. There are a variety of SSL certificates, but most start at $50/year.
