I have thought about this actually. It sounds really interesting but at $1500 for 90 days of access I'll need to make sure to find a time when I don't have much on my plate for 90 days. How much time per week do you feel you need to dedicate to it? Are you enjoying the process?
They’ve changed this recently actually, its $799 for 12 months of lab access and some entry level certs. I signed up for this and will pay the extra for the OSCP once I’m ready!
