Relay Server enables secure, load-balanced communication between mobile devices and the Unwired Server cluster. Across-the-firewall deployment occurs without opening any internal firewall ports for enterprise mobilization and ensures that data is secure while in transit.
Unwired Platform uses a relay server as a component of the enterprise demilitarized zone (DMZ), to securely integrate mobile devices into your system landscape. You need not install any Unwired Platform components on the carrier network or outside your firewall; they can all be installed and controlled within your corporate networks.
Unwired Platform synchronization uses Relay Server end-to-end encryption and HTTPS to secure communication. Devices synchronize with Unwired Platform securely on the device client side.
