ICT Diensthoofd - Head of ICT at Azwest
Consolidating user access boosts productivity by simplifying navigation
The most helpful features of Citrix XenServer are that you can consolidate everything onto one web page. For our use case, this is probably the easiest solution because there are many different software applications running in our environment. The benefits from using Citrix include increased productivity, as users don't have to search for what they need to open. They can see everything in one place instead of having numerous links in Chrome or on their home page. They simply go to our Citrix page and see everything they need. We can also specify access permissions per user, so they only get the software they require. If users have lists or reports they need to create, we can add the icons on Citrix, and they can open them directly. Everything is in the same place, so they don't have to search for anything anymore. This is the biggest productivity increase.
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.
