We use it for our internal firewall, IPS, web proxy servers as well as other devices to monitor traffic within those environments without having to purchase 3rd party products that are expensive. It's easy enough so any one can manage but is not cheap at this time when they have an annual licensing fee of $35k per site plus support fees of around $200-300/month. Not all features work perfectly which means we need additional licenses for some functions like bandwidth allocation etc. This does not seem worth purchasing if their pricing structure changes drastically or there isn't much value added over what your using now such as Fortigate FWSM - where I think many providers should look into buying licences rather than creating similar functionality themselves since its easier to integrate with existing systems. I like that it allows me to monitor all of our servers from one place, so I can quickly see what's going on. It is easy enough for anyone to use, but not too easy. Sometimes it takes a few minutes to load, which is annoying. If you are looking for an easy to use solution for your network monitoring needs, this is it! We have been able to easily monitor all of our servers from one place, and we can also get alerts when something goes wrong.
