The initial setup is easy. Right now what we are using is a product that comes in as a single virtual machine where you have a central server and a login.  

It is easy to install, but when it comes to configuration, it all depends on your events per second count. Once you get to a certain rate of EPS count, then you go on to the standard format of taking the sensor out and installing these three components separately. This may seem a little complicated but there is lots of product installation support available from AlienVault and AT&T. The integration support comes with plugins for various devices. So it ends up being really easy to install and expand.  

In some cases, we have run into a few installation problems, but AT&T has helped us to rectify those. In some cases, they go directly into the system and then try to see what is wrong and then rectify it.
