Actually, it checks to make sure your ports are closed so nothing sneaks in the back way..lol
and it also shows you what kind of info your browser gives to the pages you visit..and it shows about cookies..and just a whole lot of security things you can  control yourself if you just do them...By the time you are done your computer will not be able to be seen by hackers...etc.   You will be running in total stealth mode.  lol
