Founder of this site and lead instructor is drs. Marcel Feenstra, FRSA MALD MBA, an accredited CompTIA-, EXIN-, and ISACA-trainer. He has worked in IT for more than thirty years, is a CompTIA Certified Technical Trainer (CTT+), holds a large number of IT certifications (including CISSP, CISA, CRISC, and CISM), and has been a Professor at several Universities of Applied Sciences in the Netherlands. A Fellow of the RSA, he has a strong interest in making quality education available to everyone, regardless of income.


I found drs. Marcel's teaching excellent. I undertook an intensive 5 day CISM course and it was immediately apparent drs. Marcel was very experienced as he was able to break down complicated areas into manageable "chunks" using real-world scenario's. Questions were encouraged so that I (and my colleagues) could fully understand the areas under discussion which resulted in me having sufficient confidence to take and pass the final exam. I would highly recommend drs. Marcel as a teacher. — Andrew Richardson


I am pleased to recommend Marcel for his exceptional training and advice that enabled me to attain my CISA credentials. Marcel's extensive knowledge and expertise, coupled with his excellent communication skills, good humor, and approachable nature, made the learning experience a very enjoyable one.

Throughout the extensive course he was always enthusiastic and available to clarify or help answer any questions. This helped enormously in preparation for the CISA exam. I wholeheartedly recommend Marcel to anyone seeking professional training and consulting services. — Gerard Doeswijk


I had the privilege of being a student of drs. Marcel Feenstra for the CISA exam, and I can say that he is an exceptional teacher. Marcel has the remarkable ability to make challenging topics understandable through effective use of examples. His thorough explanations and willingness to address questions create a supportive learning environment. Marcel's passion for the topics he explains are evident, and I wished there were more teachers like him. — Timo Farla
