Guidepoint Security - CTF
This CTF (Capture The Flag) is organized annually by the company Guidepoint Security and took place between October 12th to October 18th.

You could join this CTF either with a team or solo. I chose to join the ctf with around 5 other friends. In the end our team finished 18th place.
Challenges
The difficulty of the challenges was definitely doable. I managed to solve one 100 point challenge.
Sadly, due to time constraints I didn't manage to solve any more challenges. However, the experience was still valuable and we learned a lot from participating in the CTF.
