About me

Hi! I’m Cas, an offensive security enthusiast and Red Teamer based in the Netherlands. I like to play around with anything that is related to hacking, security, programming languages, or tech in general. I love to learn, but I love sharing the things that I have learned even more - that’s what this blog is for. If you would like to get in touch you can do so via Twitter or email. I’m always up for a chat about (offensive) security and the latest new programming languages!
These days most of my time goes into Offensys, the company I co-founded. We build a Continuous Purple Teaming platform that runs realistic, behavior-based attack simulations, so security teams can see which of their existing tools actually fire.
