Tired of Offensive CTF challenges?

Try our Defensive CTF where you're presented with a number of challenges each with a vulnerable service. Your task is to patch the service whilst keeping it accessible. Based on how fast you do it, you get points - and whoever gets the most points wins the CTF.

Sounds easy? It's not! So join us. Please note that a conference ticket is required for onsite CTF participation.

The CTF will run approximately from 5-10PM on Oct 7 and you can sign up directly in the CTF platform on the day. Watch this page for details.
