Free Secure Code Trainer
Review real code snippets, spot the security flaw (SQL injection, XSS, command injection, weak crypto and more) and learn the secure fix. Free, from Neurobyte.
About this training
The cheapest vulnerability to fix is the one caught in code review. This free secure code trainer shows you real code snippets containing a security flaw — SQL injection, cross-site scripting, command injection, weak cryptography and more — and challenges you to find it, then explains the vulnerability and the secure fix. It's deliberate practice for the skill that prevents bugs from ever shipping.
It's ideal for developers strengthening their security skills and for teams running secure-coding upskilling. The flaws are drawn from the same categories as the OWASP Top 10, so it pairs naturally with our OWASP explorer and the Vulnerable Web App Lab for end-to-end learning.
Frequently asked questions
What vulnerabilities does the trainer cover?
Common, high-impact classes: SQL and command injection, cross-site scripting (XSS), insecure deserialization, weak or misused cryptography, and similar flaws from the OWASP Top 10 — each shown in realistic code with the secure fix.
Who is this for?
Developers at any level who want to write more secure code, and teams running secure-coding training. It builds the review instinct that catches flaws before they reach production.
How does it relate to the OWASP Top 10?
The snippets map to OWASP Top 10 categories, so you can learn the theory in our OWASP explorer and then practise spotting and fixing the same issues in real code here.
