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

Less hype

More value

If we were to describe what we are trying to do in simple words, it would be 'solving defenders problems' one problem at a time, providing straightforward yet reliable solutions.

Community powered

The best projects are community-driven ones. Our users are our partners. They drive, shape, and lead vision execution.

Security professionals from leading organizations use CyberDefenders

About CyberDefenders

The idea of CyberDefenders came through when both co-founders were working on a joint project to train a team of security analysts. They noticed the absence of a "user-friendly" training platform for BlueTeams. There are many valuable resources online, but they are scattered and come in various formats (i.e., SIEM, log analysis, PCAP analysis, reversing, forensics...etc.). Most importantly, it takes a lot of time to build and run.

Each defensive skill follows a different approach when it comes to setting up the practice environment and finding the proper validation mechanism, unlike the offensive side, where getting root or system access is what it takes to prove and validate a specific skill.

Our goal is to help the community practice with quality resources, use their time efficiently, and connect with fellow professionals. Another thing we hope to achieve is to help defenders market for their skills by sharing their content publicly. Aside from being an effective way to contribute and share knowledge, creating content in itself is a great learning experience and a proven method to build your brand.

We don't like to brag, but we don't mind letting our users do it for us. Here are a few nice things folks have said about what we do.


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.


What services do you offer?

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


What is BlueYard?

BlueYard is is a community initiative to collect archived BlueTeam challenges in one place to make it easier for security professionals to practice with quality resources and make these challenges live forever.


How to add a challenge to BlueYard?

When a live CTF ends on BlueRing, the CTF challenges are moved to BlueYard to make them accessible for the community and enrich the CyberDefense content.


What are challenges?

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.


Can I add or refer challenges?

Sure, we encourage fellow defenders to create 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.

Are new courses added regularly??

Absolutely! We will always be adding new content in the relevant areas that will help fellow defenders develop competency.
