Frequently asked questions

What is CyberDefenders?

CyberDefenders is a training platform focused on the defensive side of cybersecurity, aiming to provide a place for blue teams to practice, validate their skills, and acquire the ones they need.

We provide three primary services: a live CTF hosting platform (BlueRing), a professional training platform (BlueDemy), and a hands-on practice area (BlueYard).

BlueYard is is a community initiative to collect quality Blue Team challenges in one place to make it easier for defenders to practice with quality resources and make these challenges live forever.

If you have a blue team/threat hunting/digital forensics/incident response/threat intel/malware analysis challenge, reach out via our Discord server #submit-challenge channel.

Challenges are blue team exercises meant to provide a way to practice CyberDefense skills. They come in different formats such as attack investigation (SIEM style), PCAP analysis, memory analysis....etc. Each challenge has its scenario and list of questions. Answering questions correctly requires going through an investigation scenario, analyzing data, and extracting the right piece of information.

Sure, we encourage fellow defenders to create blue team challenges, and we will publish them under their names. If you master a specific defensive skill, 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. If you have something in mind but do not where or how to start, please get in touch to discuss it further.

BlueYard is entirely free to play. BlueRing is free for educational institutions and non-profit organizations. Bluedemy training's fees depend on the course topic and delivery method.
