Application security is one of the most critical skills in tech. And one of the biggest knowledge gaps. AppSecHub is the learning platform and community for developers, security engineers, and tech professionals who want to understand, practice, and master AppSec together.
Every module starts from the offensive perspective.
How vulnerabilities are discovered, chained, exploited, trace the root cause, and patch them properly.
SQLi, SSRF, IDOR, XSS.
Based on patterns found in real bug bounty programs and penetration tests. Not theoretical examples.
We teach the fix and the reasoning behind it.
Patching without understanding is how the same bug comes back.
