Login VSI provides proactive performance management solutions for virtualized desktop and server environments.

Enterprise IT departments use Login VSI products in all phases of their virtual desktop deployment—from planning to deployment to change management—for more predictable performance, higher availability and a more consistent end user experience.

The world's leading virtualization vendors use the flagship product, Login VSI, to benchmark performance. With minimal configuration, Login VSI products works in VMware Horizon View, Citrix XenDesktop and XenApp, Microsoft Remote Desktop Services (Terminal Services) and any other Windows-based virtual desktop solution.

The engine that powers Login VSI products is unique in the industry in that it simulates real user activities using synthetic users and includes pre-configured workloads. By using virtual users instead of real users, Login VSI can deliver more predictable testing results and monitoring insights that ultimately benefit the end user experience.
