If your domain stores sensitive data, such as customer profiles, Ensim recommends that you secure your domain. To secure a domain, you need a Secure Sockets Layer (SSL) certificate
SSL is a protocol that transmits private documents through the Internet. It creates a secure connection between a client and a server over which any amount of data can be sent securely. SSL works by using a private key to encrypt data transferred over the SSL connection.
SSL certificates are available from a Certificate Authority (CA), such as Verisign.
This topic explains how to obtain an SSL certificate and load it onto your Web site.
