Mobile secure gateway

Mobile secure gateway (MSG) is an industry term for the software or hardware appliance that provides secure communication between a mobile application and respective backend resources typically within a corporate network. It addresses challenges in the field of mobile security.

MSG is typically composed of two components - Client library and Gateway. The client is a library that is linked with the mobile application. It establishes secure connectivity to Gateway using cryptographic protocol typically SSL/TLS. This represents a secured channel used for communication between the mobile application and hosts. Gateway separates internal IT infrastructure from the Internet, allowing only an authorized client requests to reach a specific set of hosts inside restricted network.
