What cybersecurity professionals are saying
Lane Baker
Of all the tutorial/education videos I've watched in the short time I've been in this field, this material is by far the best I've come across. I don't comment on videos very often, if ever, but you definitely should know that this is practically the gold standard!

I just wanted to say thank you for your videos. I have followed your recent video on creating a home lab and while you went through it in just under 2 hours it took me 3 1/2 or 4 to follow along and install/configure mine at the same time. I was amazed that absolutely every single thing you taught worked on my end, I have followed along with others where small differences have led to hours/days of trouble shooting on my end. Any way I just finished the tcpdump & wireshark video and wanted to say THANK YOU for your clear and patient teaching style. I will watch other videos and then sign up for your paid lab course soon as well!

I needed a good cram session. I found your lesson last night 11/29/2024 the night before my exam. I passed the exam today 11/30/2024 after watching your video. I needed this. Great Work. Thank You.
