Pulling directly from the site:
The Portspoof program primary goal is to enhance your systems security through a set of new camouflage techniques. As a result of applying them your attackers’ port scan result will become entirely mangled and to very significant extent meaningless.
From what I can gather it makes it “harder” to determine which ports are actively open on a server.
So my question is that really effective in the real world?
I also so that it has what it calls “Exploitation Framework Frontend” but im not sure what to make of that.
