Using the BlackBerry Enterprise Server as an intranet gateway

Organizations host the BlackBerry® Enterprise Server behind their firewall to allow BlackBerry device users to access the organization's intranet. The BlackBerry® Mobile Data System component of the BlackBerry Enterprise Server includes the BlackBerry® MDS Services, which provides an HTTP and TCP/IP proxy service to let third-party Java® applications use it as a highly secure gateway for managing HTTP and TCP/IP connections to the intranet. When you use the BlackBerry Enterprise Server as an intranet gateway, all data traffic between your application and the BlackBerry Enterprise Server is encrypted automatically using AES encryption or Triple DES encryption. Because the BlackBerry Enterprise Server is located behind the organization's firewall and provides inherent data encryption, applications can communicate with application servers and web servers that reside on the organization's intranet.

If your application connects to the Internet rather than an organization's intranet, you might be able to use the BlackBerry Enterprise Server that the device is associated with as a gateway. In this case, network requests travel behind an organization's firewall to the BlackBerry Enterprise Server, which makes the network request to the Internet through the firewall. Organizations can set an IT policy to enforce the use of the BlackBerry Enterprise Server as the gateway for all wireless network traffic, including traffic destined for the Internet.
