Here's What People Are Saying About Cybersec Trainings

Emanuel Paun

Mohammad was an amazing professor. I do not have a strong networking background and Mohammad was very patient in teaching me the basics in topics like wireless. The way he taught (hands on/labs) really helped solidify everything we learned through the 5 days of classes. I have nothing but positive feedback for the way he taught these course and his personality was amazing. 10/10 professor.

Alberto Feoli

Mohammed did it very well and way he explains concepts very good! Thanks for all your time and effort to help us understand.

Agnes Audige

Mohammed was able to present the class with real-world examples and kept me constantly engaged.
