XenClient is a desktop virtualization solution from Citrix that runs secure virtual desktops on endpoint devices. Desktops are run locally, without hosting applications or the operating system in a datacenter. It consists of a Type-1 Xen client hypervisor and a management server, which provides features such as centralized provisioning, patching, updating, monitoring, policy controls, and de-provisioning. It enforces security through features including AES-256 full disk encryption, VM isolation, remote kill, lockout, USB filtering, and VLAN tagging. XenClient supports use cases such as disconnected operation on laptops, limited connectivity environments (such as branch offices), and other use cases where use of local execution is desired and centralized management is required.
