How do you improve Open Source Security?

Recently we started CTF365 which is a “Security Training Platform for IT industry” with a focus on Security Professionals, System Administrators and Web Developers that implements CTF (Capture The Flag) concepts and leverages gamification mechanics to improve retention rate and speed up the learning/training curve.

We did created an internet alike environment (domains registration included) to make it look like the real Internet where users can build their own servers and attack others while defend their own.

It is build such way that anyone can get or experiment with Brute Force, SQLi, Deface, Take Over, CSFR, RCE, Private Enumeration and so on without any restriction.

Among being used as a security training platform for IT Industry, we discovered that can be used by Open Source community to help them improve their apps security.

My questions is:

Would CTF365 be a great opportunity for Open Source community to improve your product security?

As a Open Source project manager or developer leader, would you use it for your product to learn how hackers would attack your setup/app?
