Frequently Asked Questions
Common questions about CyUnified, our content, and how to get involved.
Is CyUnified free?
Yes. All lessons are free to read, with no account required and no paywalled content.
Who is this content for?
Developers who want to write more secure code, and anyone learning application security fundamentals or preparing for security roles and interviews. Lessons assume basic familiarity with how web applications work (HTTP requests, cookies, databases) but not prior security experience.
Can I contribute an article?
Yes — we welcome contributors. Email us at cyunified@gmail.com with what you'd like to write about. Every contributed article goes through review before it's published.
Is it legal to practice the techniques described in these lessons?
Only against systems you own or have explicit, written authorization to test. See our Disclaimer for the full detail — testing a system without authorization is illegal in most jurisdictions regardless of intent.
How often is content updated?
We add and revise lessons regularly. If you spot something outdated or incorrect, please let us know — see the next question.
I found an error in a lesson. How do I report it?
Email cyunified@gmail.com with the lesson name and what looks wrong — we appreciate the correction.
I found a security vulnerability on this website itself — where do I report it?
Please see our Report a Vulnerability page rather than the general contact form — it explains what to include and what to expect.
Do you offer certificates or certifications?
Not currently. CyUnified is focused on teaching the material itself, not issuing credentials.
