Citrix Worx is a line of certified mobile applications for the enterprise. Security, policy and provisioning for Worx apps are controlled by Citrix XenMobile.
XenMobile allows administrators to make Worx apps available to employees through an enterprise app store. End users access this store through the Worx Home app on their devices. IT administrators can apply and enforce specific management and security policies to Citrix Worx Mobile Apps. They can, for example, limit the sharing of data from one app to another, or require an application-level virtual private network connection for certain apps to work.
Citrix Systems offers Worx versions of its proprietary apps, such as GoToMeeting and ShareFile, as well as a secure, managed email client and Web browser. The company also provides a software development kit (SDK) so independent software vendors (ISVs) and corporate developers can create and certify their mobile apps with Citrix XenMobile.
