Signed up for Offensive Security
i signed up for the offensive security course today. i learned about BT3 from someone at work; i am an IT security consultant looking to further my knowledge, and I know this course is going to be great.
That is a decision you will not regret.
You will love it.
There will be pain along the way, but the knowledge and hands on experience you will gain along the way will make it all worth it. (not to mention all muts' little tips and tricks)
Money well spent.
