Besides being a speaker on open source and infosec conferences, I help the NLUUG, a UNIX user community in The Netherlands. Besides being a board member (secretary), I’m also part of the program committee. Together we find new speakers, with my personal focus on increasing the quality of the conference. Supporting tasks include doing promotion on social media and ensure that speakers are treated in the best way possible.


Information sharing is something I love to do. Definitely taking a lot of time to do, but worth the effort, seeing the many positive comments. I’ve now contributed over 180 articles for the Linux Audit blog.


To help younger people in the field of information security, I’m a mentor to a few people per year. I help them to make the right choices. This includes suggestions for certification and achieving actions to further progress in our field. No one was born as an expert, but we definitely need more of them.
