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.

What our customers are saying

Eduardo Molina - RoundTower Technologies

"Login VSI support is fantastic. I had one issue, things were not working. I sent an email, got a call the next morning and the guy knew exactly what I was talking about and we just solved the issue in less than an hour. And that was one thing that was really, really great, the support that we get from Login VSI is fantastic."

Eduardo Molina, Virtualization and Cloud Architect at RoundTower Technologies

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."

Johnny Blizzard, Sr. IT Systems Engineer at a Health Insurance Organization

Maarten Bruijnesteijn - PPG

"We are using Login VSI for hardware scaling. By testing the number of users that can run on our environment, we know the amount of hardware that we will need upfront. We also use Login VSI in our production acceptance process to test changes to the system to evaluate changes to the environment."
