Abstract: A processing device comprises a processor coupled to a memory and implements a secure container for accessing data over a network. The secure container is configured to interact with backend infrastructure of an enterprise in order to provide secure access to enterprise data at the processing device. The secure container may be configured in accordance with an access model that implements multiple-factor authentication in combination with active directory authentication. The backend infrastructure may comprise, for example, a threat management gateway and an application control engine coupled to the threat management gateway and configured to support the multi-factor authentication, as well as additional components such as an active directory, a data loss prevention engine adapted to process communications between the backend infrastructure and the secure container, and a proxy server providing access to a content adaptation server configured to filter communications received from the processing device.
