We encourage fellow defenders to create challenge and join our respected list of challenge authors . If you are good at something, why not let others know about it, be it SIEM, log analysis, packet analysis, reversing, forensics, or engineering. Trust us; the community is hungry for quality resources.
Aside from being an effective way to share knowledge, creating challenges in itself is a great learning experience and a proven method to build your own brand.
You can also refer challenges you came across somewhere else. If you have something in mind but do not know where or how to start, please feel free to get in touch, and we will be more than happy to help.
