An SSL, or Secure Sockets Layer certificate, ensures that all data passed between the web server and browsers remains private. You'll need this when you have e-commerce on your site. For this, we recommend our Security Service Add-On. We?ll add an SSL certificate to your site. This add-on is available for the monthly fee of $9.99. If you?d rather purchase an SSL certificate directly and provide us access, that?s an option too.
