Featured Reviews

Tanvir Siddique - PeerSpot reviewer
Technical Officer at ADN Telecom
Easily accesses open solutions with seamless compatibility for testing and development
The most valuable feature is the seamlessness. When I install a Linux operating system, I can use Windows applications through Oracle VM VirtualBox seamlessly. There are many applications that work only on Windows. For desktop testing purposes, I used Oracle VM VirtualBox, and it works fine. The guest OS compatibility was tremendous because I used Oracle VM VirtualBox on Linux and ran Windows applications on top of that, working seamlessly.
Bruna Müller - PeerSpot reviewer
License manager at a financial services firm with 10,001+ employees
Centralized asset data has transformed how we manage licenses and make cost-saving decisions
One problem that we faced using Spot by Flexera is that in certain servers, the data was not being updated correctly, and we had a certain delay. For example, someone was using a computer, and then this user received a new one. In Spot by Flexera, we could see both computers, the old and the new one, but the system was not recognizing that the old one was no longer being used. We had a couple of IT assets that were not being used, and we had this information in our internal servers, but Spot by Flexera was not able to update on time. We had to fix this information manually.
