About TLS

The browser is designed to use TLS or SSL to encrypt data that your BlackBerry smartphone sends or receives over the Internet through the BlackBerry Enterprise Server. Communication between your smartphone and the BlackBerry Enterprise Server is encrypted using Triple DES. Communication between the BlackBerry Enterprise Server and content servers is encrypted using SSL or TLS. To increase security, you can set up TLS for HTTP connections between your smartphone and the BlackBerry Enterprise Server and use Triple DES encryption for all other communication between your smartphone and the BlackBerry Enterprise Server.

Browser security options

If your email account uses a BlackBerry Enterprise Server, you might not be able to change your browser security options.

If you change a browser security option, other applications on your BlackBerry smartphone that access a server might be affected.
