David has been a network engineer, consultant, security designer and architect, author, and technical instructor since the early 1980s and has specialized in IT security and compliance work in the recent years. He has been an instructor with SANS since 2012. David is the lead instructor for the CISSP certification course, and his students consistently rate David's lectures as excellent. A recent survey showed that approximately 93% of the students attending his CISSP classes passed the very challenging 6-hour certification exam on their first attempt.
David does a great job presenting the material and relating it to real world situations. Class pace is perfect.
This course was great. David knew his stuff and had meaningful input on every relevant CISSP question that was asked of him. I feel like this course helped to solidify skills that I have with relevant information and helped me think about cyber security in a much more holistic way.
David is obviously very knowledgeable and I think he's a very good instructor. You can tell he really cares about his job. He has also made himself very accessible during and after class.
Here are upcoming opportunities to train with this expert instructor.
