The mobile agent is a Linux-based appliance that lets you secure the type of email content that is synchronized to users' mobile devices when they connect to the network. This includes content in email messages, calendar events, and tasks.
The mobile agent analyzes content when users synchronize their mobile devices to your organization's Exchange server. If content or data being pushed to their device breaches the organization's mobile DLP policy, it is quarantined or permitted accordingly.
Deploying the mobile agent
In your network, the appliance connects to the Data Security Management Server and to your Microsoft Exchange agent to provide this function. DLP analysis is done on the appliance or on other Data Security servers (rather than on the management server) to optimize performance and balance the load. Outside your DMZ, the mobile agent connects to any Microsoft ActiveSync-compatible mobile device over 3G and wireless networks, such as i-pads, Android mobile phones, and i-phones. (ActiveSync is a wireless communication protocol used to push resources, such as email, from applications to mobile devices.) Unlike the protector, the mobile agent appliance acts as a reverse proxy, because it retrieves resources, such as email, from the Exchange server on behalf of the mobile device. The following diagram illustrates the system architecture of a typical mobile agent deployment. Depending on your network and security requirements, you can also go through an edge device, such as a Microsoft ISA Server, that acts as a reverse proxy to the mobile agent.
