As companies embrace mobile IT, the mobile app is becoming ubiquitous. It is important that the data these enterprise mobile apps use are securely transmitted. MobileIron AppTunnel provides secure tunneling and access control to protect app data-in-motion. Fine-grained app-by-app session security protects the connection of each app container to the corporate network. It builds upon the proven MobileIron Sentry technology, which is installed at thousands of customers. MobileIron does support 3rd party VPN, but AppTunnel is particularly useful in BYOD settings where organizations may not want to open up VPN access to all apps on the device, but would instead rather offer more granular access to specific applications and related data. By not having to require a VPN connection, the native user experience for mobile access to applications and content is also preserved. An app that is protected by AppTunnel opens like any other app on the mobile device. The extensive security is totally invisible to the end user.
