Free AppSec Training

Secure Coding Developer Training

At Global Learning Systems, we want every software engineer to have free access to developer security training. These free training exercises – including OWASP Top 10 for Web and API, AWS Top 10 and Front-end Top 10 – are the first steps in that direction. Inspired by real-world vulnerabilities and case studies, we have created a series of interactive application security training modules to help developers understand, identify and mitigate security vulnerabilities in their applications. Have fun and take the free training now!
