Career
Joep became known among security professionals after an article of his writing appeared on the technology-related news website slashdot on January 23, 2006, stating that "current approaches to Information Security are fundamentally wrong". With this, and other ideas, he gives talks at conferences, universities and communities throughout Europe. From January 2000 to January 2003 he was a programmer and consultant for iKloak, a Dutch vendor of security products.
In October 2004 he left the company as technical director of Research and Development.
After working for the Dutch security company Kahuna in 2005, he worked for Motiv Information Technology Masters as a consultant. In 2007 he started the NCECC, which stands for Northern Continental Europe Cyberspace Command, that aims to "provide state-of-the-art intelligence, defensive and offensive services to better understand, protect against and fight sources of cybercrime and cyberterrorism".
From 2007, he served at iSIGHT Partners - eventually as the Senior Director of Global Intelligence. In 2014, he founded the Information Technology Security software EclecticIQ (initially Intelworks).
