A common request from users is to access their applications outside the company, using different types of connections. The ICA protocol used by XenApp is designed to also work with low-speed, high-latency connections; system administrators can also use some advanced features to improve the user experience.

Citrix offers a family of network accelerators, CloudBridge, which can be used to optimize the connections through WAN or mobile links.

WANem, an open source tool, is helpful to simulate how applications behave with different connections. With the deployment of NetScaler Insight, network data is available in Citrix Director.
