While studying ICT back in the day, Annelies discovered early on that ICT is not accessible for many (if not most) people. Even though after that she didn't go into hardcore IT, she always kept connecting to the tech industry in various ways, for example by having a blog about consumer tech. Since 2018, she has been diving into accessibility and what this means for businesses and the people who make the digital world. She has been spreading awareness and sharing insights and tools in several podcasts, webinars, (international) events and more for a few years now. Annelies is an accessibility expert at Accessibility Desk/Digitaal Toegankelijk in Utrecht, The Netherlands.

I’ve always admired those that said “You will not have to work for the rest of your life if you make money from your hobby”. Especially if it meant a true “impact that matters” for people and networks, so my goal was to become one of the best incident responders out there. While it was fun to study and play with my friends in “Aggressive Cake” (a fitting name for a CTF team) in an effort to break into the cybersecurity industry, it soon became apparent that reality is far from the innocent dream of doing what you love.

4 years forward, and really started wondering, if it would be better to become a fisherman. After all, the sea tides are less harsh than the life of a responder. Working overtimes to get the thrill of catching the bad guys was not worthy. Sometimes I pray that AI takes this job (and auditing) away. Thankfully my remaining soul shards and weekends were saved by switching to purple teaming. I now craft detections and research cloud security within FalconForce. I like petting stray dogs and watching sunsets.
