Sensitive or confidential data must be encrypted in transit
Communication encryption (SSL/TLS) ensures non-accessibility of data.
Any site accessible via the internet should use the TLS protocol.
SSL certificates are commonly used to secure and authenticate communications over the internet and within corporate intranets.
When visiting a web site that is secured by a certificate, the user can see several visual clues in his Web browser confirming that encryption is enabled.
For example, the address in the browser's address bar will start with https: // for SSL/TLS-secured connections, and http: // for non-secure connections.
