Although Apple offers a lot of options for protecting other kinds of Web traffic, none of them is perfect. Lets check this alternative

Use a VPN
VPNs wrap all data entering and leaving an operating system over a network its including e-mail, Web data, and widget communicationsin strong encryption.Apple supports two popular forms of VPN client software: PPTP (Point-to-Point Tunneling Protocol) and L2TP, often known as IPsec (IP Security) over L2TP (Level 2 Tunneling Protocol). Unfortunately, if your company requires the use of an RSA SecurID token, a key fob or card key to generate a special password for access, you’re out of luck. Users of VPN systems that use digital certificates or Kerberos, as well as a few other options, can’t make connections either. However, the L2TP/IPsec client will support tokens from CryptoCard, as long as the “shared secret” method is used.

Set Up Secure Web Proxies
One option is to use a secure Web proxy service, such as Dogoso or Secure Tunnel . The secure proxy creates an SSL connection between your browser and Secure-Tunnel’s servers, rendering your sessions inaccessible to local Wi-Fi network snoopers. To set up a secure proxy for Web
access, go to Settings: Network: Wi-Fi. Unfortunately, the setting works on a per connectionbasis. You’ll have to reenter the same proxy data tediously every time you connect to a different network, making it a rather impractical solution for most users
