I have seen the offensive security penetration testing labs; they are amazing but costly. Is there any other online virtual penetration testing lab I can SAFELY conduct penetration testing and exploitation against? I do not mean machines I can download, I mean online labs or sites.

  • As you say online labs, are you talking web apps / web servers rather than OS, or are you looking for online virtualised windows/linux labs? if you are looking for web, then first take a look at hack yourself first (from Troy Hunt) and Hack This Site (that's a name, not an instruction ;- ) )

  • @iain I meant both, but operating systems are better
