About CyUnified

CyUnified is a free, practical cybersecurity learning platform. We write lessons the way we wish security was taught to us — concrete, example-driven, and grounded in how real vulnerabilities actually work, rather than definitions alone.

Why we built this

Good security education is often locked behind expensive certifications or scattered across blog posts of wildly varying quality. We wanted one place with a coherent, numbered curriculum — from authentication and authorization fundamentals through to the vulnerability classes covered in the OWASP Top 10 and beyond — that anyone could work through in order, for free.

What you'll find here

Structured lessons covering web application security, from the fundamentals (authentication, session management, access control) through specific vulnerability classes (IDOR, CSRF, SQL injection, SSRF, and more), each with concrete request/response examples, testing methodology, and prevention guidance — written for learners preparing for security roles or interviews, not just for passing a quiz.

Who's behind it

CyUnified is maintained as an independent project, with contributed articles from other security practitioners. Every contributed article is reviewed before it's published, so what you read here has had a second set of eyes on it.

A note on how to use this content

Everything here is written for education and for testing systems you own or have explicit authorization to test. See our Disclaimer for the full detail.
