What do you think about this tool, useful or not? It would not install on my virtual machine btw, but perhaps you all won´t have any problems.

Looks like interesting,it's a packet filter firewall but added signature-based
technology,it's useful for enterprise environment.

 

Yes on second thought I think this tech should rather be integrated in home firewalls perhaps, could be useful. If anyone has checked it out, let us know.
