Common questions
Can I get into security with no experience?
Yes. Showing you can find and fix real vulnerabilities is the strongest signal - more convincing than certifications alone, especially early on.
Do I need to be a developer first?
It helps a lot. Most application-security work is reading and fixing code, so the projects here are hands-on code fixes, not just theory.
Which certifications matter?
Certs can open doors, but hiring managers want proof you can secure real systems. A portfolio of fixed vulnerabilities pairs well with any cert.
