Capture the Flag (CTF) – Netherlands National Tournament

Solve Problems, Compete, Practice, Learn and Have Fun

SANS is excited to present the Netherlands National CTF Tournament for 2021.

Last year’s edition was such a hit and we received a lot of great feedback from all players. We’re back this year with the second edition of this National Tournament. It will host hundreds of players from all across the Netherlands and is taking place end of October. This CTF is free to enter and will provide an opportunity for participants to compete on one of SANS’ latest CTF exercises and to win prizes.

What you will also find is that since our first run last year, our CTF Development team has put in a lot of hard work to build a vast amount of new challenges ranging from “easy” to “extreme”, ensuring we’ve got something for players at all levels.

Do you think you’ve got what it takes and are you ready to take on your fellow Dutch cybersecurity community members? Sign up below and we’ll see you on the 28th of October!

Dates: October 28th - 29th 2021

The challenges in this free CTF are perfect for all cybersecurity professionals and use real-world scenarios, testing their skills across a wide spectrum of cybersecurity disciplines in a fun and competitive environment.

I really enjoyed the challenges and the “real-life” aspect of the CTF. I am very much looking forward to the next SANS CTF tournament!” – CTF player from UBS Switzerland
