Is Ghostwall better than Windows firewall ? Being so user dependant, I'd say it has the potential to be much better in the hands of an expert user. But it's not going to give any feedback and isn't going to advise you if something tries to call in or out. It gives you the opportunity to set your own rules and comes with a default set that's probably OK for many users. But I think to get the best from it you need a fairly good grounding in what the communication ports do and how you want them to behave. Not for casual users IMHO.
