Kaseya VSA

Best feature... remote access to end-points! This allowed our small helpdesk team us to monitor and manage hundreds of end points (mostly desktops) all over different sites. No need to physically go to the office to install a patch or troubleshoot.

Also, it was very useful for our hardware and software inventory. The reports are easy to generate and use especially for budget decisions.

We get to monitor also unauthorised software, and sometimes, with the consent of the respective pc users, we get to monitor their pc activity in real-time.

Plus! It supports all our devices (mac to pc and even linux, iOS and android).

Functionality wise, I have no complaints. However, in terms of UX, it looks a little dated. Perhaps the interface navigation can be improved.

This software is very full-featured and allows quite a bit of granular control and automation. It continues to improve and has a nice amount of features that are included.

Features that would be nice to have in the base version must be purchased as additional plug-ins so that one feels somewhat "nickeled and dimed" every time you want to expand your feature-set.
The cost is on the higher end for a remote management product which could be justifiable if the support were better. I have found that it is a mixed bag of tricks in terms of how quickly you get a response and every time my ticket is addressed it is outsourced to someone for whom English is a 2nd or 3rd tongue. I don't have a problem with the outsourcing aspect but I often find there is more than a bit of a communication gap and it can be frustrating spending a solid chunk of time trying to get my point across due a language barrier. If this were a very low-cost product this would be more understandable but it is not.
There is also a very solid learning curve in terms of understanding all of the features. They offer a Kaseya University option to address that (which I am currently involved with) but it requires a subscription that keeps having to be renewed or you lose access. As the content is static, it would be much better to have a pay once and access forever -certainly for the same version.
