Difficult content with a good teacher. Some moments were hard to parse (albeit comprehensive), although Gian's reassurance that the high-level overview mattered more than the individual steps was heartening.

Awesome. I'm a laid back slacker dude IT guy who's politically on the other side of this area WHICH IS WHY I benefited from the course. Will certainly be hardening one or two networks this year as a result.

A very comprehensive look at IT Security. I've learned everything from encryption and decryption to whitelisting, and how it pertains to real-world scenarios. Very useful to learn when it comes to IT.

Good course! A lab using some of the tools like Nessus, OpenVAS or Qualys, and a lab demonstrating

penetration testing or vulnerability scanning could help learners better visualize these processes.
