Offensive Security&#x27;s PWK course is probably your best bet. In-depth training and a highly-regarded certification. Online mentoring via web forums and IRC and they are great folks.<p>I went through PWK and its predecessor PWB.<p>It&#x27;s pretty damned cheap and you can get from 30-90 days lab time. I recommend 90 days, though.<p>It is kinda boot camp style and pretty demanding. You will learn how to chase the EIP CPU register and write your own exploits, as well as web vulns, sqli, etc etc.<p><a href="https:&#x2F;&#x2F;www.offensive-security.com&#x2F;information-security-training&#x2F;penetration-testing-training-kali-linux&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.offensive-security.com&#x2F;information-security-trai...</a>
