What is WICCA?

WICCA is a circle of women in cybersecurity based out in The Netherlands with a vision to spread the infosec word to everyone.

Our goal is to bring infosec ladies and female security enthusiasts together to learn about exploits, hacking, incident response, forensics, the low-level stuff, and especially make bad crypto jokes! We want to build a community of badass women in the Netherlands and hopefully inspire future generations to join keyboards and get the hacking started!

We meet monthly in Amsterdam, The Hague, Utrecht, Rotterdam, and more, sometimes even abroad! Are you a woman working or interested in computer security? Then by all means, do sign up!

WICCA is an entirely volunteer-driven community and all our meetups are free.


Meetups are usually women-only, but as we want to spread knowledge everywhere, we have many mixed events to share knowledge as well. The main idea is for it to be a community where women are prioritised and everyone is at ease and feels more welcome. We want to create a strong circle of women but we’re not an exclusive circle. WICCA is basically a group of badass hacker ladies, but everyone is welcome to learn from and with us! 😉

Our philosophy

In our group, we look at the positive results of the many initiatives to increase diversity in the infosec community and in the tech world in general. We focus on good work, good research, and strong efforts that makes our community thrive. We do not let negative thoughts and endless debates take too much time away from us. We goof together, we laugh together, and we hack together!
