Trainings, workshops, lectures

Below you will find a few sample video's.

I am passionate about educating people. The audience ranges from very technical to non-technical.

I have given hundreds of trainings, workshops and lectures. Some of the subjects I have talked or gave trainings about are: secure coding, supply chain security, physical security, risk management, product security, hacking, FreeBSD, IPv6, DNSSEC, Social Engineering, security compliance, OWASP, physical pentesting, IOT, RFID, and many more. I can create tailor-made sessions on a very broad range of subjects. I am known for being a passionate speaker with quality lectures, which has resulted in having been invited as a keynote speaker multiple times, and having my abstract accepted for prestigious events like t2.fi.

Some of the places I have presented are TEDx, ENISA, NIRIA, ISACA, FIRST, NLUUG, ETRI, IEEE, Nerdland, ExpertsLive and the Dutch Police.

Among the companies I have given workshops for are Rabobank, SNOW, Philips, ASML, Codean and Inventis.

I have presented at Hogeschool Breda, Hogeschool Utrecht, Hogeschool Zuyd, TIAS/NIMBAS, Universiteit Maastricht and Universiteit Utrecht.

I won a prize for the best lecture of the year ("DoVo-award") at Philips Research and best security lecture of the year at Philips Group Security.
