It does exactly what it says - it will protect against day-zero attacks (well, depending on the attack of course) and support responded quickly to my questions.

Easy to install, it auto-generates a list of installed software and assumes that they can be on the whitelist - much easier that some alternatives where you must manually itemise all that you want on the whitelist. It also asks you to allow or reject anything new. Can run on a stand alone machine (you don't have to be in a server domain).

Using the console requires great patience! It is quite slow (i.e. uses a lot of compute) when it is setting itself up (scanning all executables on your machine) and making any changes on its console is also slow.
