XenApp allows IT to deliver secure applications as a service, providing on-demand access to users while affording IT the flexibility to leverage future application architectures. It provides several benefits that make it a strategic system for application delivery. 

End-to-end Windows application delivery
Deliver 100 percent of your Windows-based applications without leaving the data center by using the state-of-the-art application virtualization technologies of Citrix XenApp. Eliminate the need to install or manage applications on individual user devices, making application testing, provisioning, management and support easier and less costly. Let the underlying intelligence automatically select the best delivery method for the user, the application and the location, and watch application performance improve dramatically. 

Strongest security for applications and intellectual property
Control, protect and retain intellectual property centrally to dramatically reduce the chance for data loss and theft. XenApp helps you prevent data from leaving the data center without your explicit permission, supporting regulatory compliance and security objectives. Built-in endpoint scans and policy controls take into account each user?s role, device characteristics and network conditions to determine which applications and data they are authorized to access. These dynamic attributes also define where users may store and print sensitive information. Such strong data and application security measures decrease the potential for inadvertent exposure, and enhance your ability to back up and restore information from one place for greater fault tolerance and disaster recovery. Integrated single sign-on and a secure SSL VPN gateway for remote access enable a ?one password, one path approach to application and data access.

Outstanding application performance over any network
Improve application responsiveness and increase user productivity with patented application virtualization techniques perfected over 15 years. Many applications frustrate users as they wait for data to be pushed across the network. Over high-latency or bandwidth-constrained WANs, these problems are even worse. XenApp greatly reduces network bandwidth requirements and mitigates latency issues, because with virtualized applications, only mouse movements, keystrokes and screen updates traverse the network. Even data-laden and graphics-heavy applications perform better, keeping users active and productive.

Fastest application delivery to all users - anywhere
Accelerate the time-to-value of your applications so you can  respond quickly to changing business needs. Manage the delivery of all your Windows-based applications from one centralized location ? no need to go from desktop to desktop, travel from office to office, or wait for laptops to return to headquarters. With XenApp, you deliver applications and updates instantly, anywhere, any time to offshore employees, outsourcers, new branch offices, new mergers & acquisitions, or mobile workforces.

Continuous availability and reliable, fast application performance
Provide high application availability for an always-on user experience with application load management, automated server recovery and failover. Troubleshoot issues quickly by using detailed and actionable reports that monitor the end-user experience and identify root-causes anywhere in the system: the application, server, network or desktop. XenApp gives you end-to-end visibility into application usage and performance, key to satisfying and verifying application service level agreements (SLAs) and increasing user satisfaction and productivity.
