About Login VSI, Inc.

Login VSI provides performance insights 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.

Whether you are using Citrix, VMware or Microsoft, the inherent complexity of your environment, compounded by constant application updates, can and will affect performance in your VDI environment. To help you to deliver a predictable performance, higher availability and a more consistent end user experience in every phase of your deployment, we would like to introduce the VDI lifecycle.

What our customers are saying

Andrew Mills - Nutanix

“Predictability is a key piece to VDI. It’s one of reasons that VDI has scared people away, but Login VSI solves that. If you’re going to do it, do it right. Login VSI really gives that rubber stamp on doing it right.”

Andrew Mills, VDI Alliances Manager at Nutanix

Shai Maskit - Kaminario

“We tested 750 seats so customers can compare Kaminario with solutions from other vendors. It really comes down to delivering the best user experience at the right price point. As soon as we show the solution and that it has been validated by Login VSI customers can rest assured that it will fit the rest of their environment.”

Shai Maskit, Director of Product & Solutions at Kaminario

Johnny Blizzard - Health Insurance Organization

"We now have indisputable empirical proof supporting our claims. With Login VSI, we can run our own applications against various hardware platforms before we move to production! Application owners can see how their code impacts their users on our systems and we can present our findings to management for funding increases. We can also advocate for the users when supporting their claims of poor performance, all because of Login VSI."
