I have heard some companies use mac ports with a mac has anyone done this ? if so how easy is it to update tools ?

Many thanks

I have not taken the HackingDojo course but I know the OSCP course teaches you most of the steps in a pentest.  The thing I was most impressed with, was the Pentest report.  That teaches you to organize your thoughts and hacks, then present them in a very detailed and comprehensible report. 

I was able to achieve and recreate each hack just by going thru my notes and practicing.  That really helps when you think of the number of machines that you are attacking.  If I had to pick, I would still go with the OSCP.  I think a beginner can get thru the course.  It just may require more time than someone with more experience. 

somehow i think providing VM's is a better solution. I know i haven't touched quite a few of the systems that are in the OSCP labs, which is a shame cause good practise is hard to get. i know its probably wishful thinking but if OSCP would provide all the systems as VM's i would have learned even more then i already did! then again they would have to rethink the whole 30/60/90 day access concept...

I guess it all depends on your experience if you are pretty new to security then Hackingdojo. If you can write bash script and know networking,bit programming,basic metasploit,nmap ect then OSCP

However Hackingdojo is really good course it teaches you what you doing rather than how to use tools so you have a much better understanding of things.

I have not done the OSCP yet but from what I heard its not easy and I would say it was more aimed at someone who has maybe a years pen testing experience.

Hacking Dojo provides you with vulnerable ISO's to work with.  It requires you to either have an spare machine to use, or just use a virtual environment (VMWare Player/Workstation, VirtualBox, etc).  I think most of us students have gone the virtual environment route.
