“A will to suffer…is required for sure in order to finish the course.”
— Wesley Neelen – dearbytes.com
"If you are already considering to take the course, don’t hesitate and just go for it – you won’t regret it."
— Michael R. Heinzl
"Having been in information security for the past 6 or 7 years and having been on various security related courses I must say that the 101 course from offensive-security is one of the best."
