In-Repository Developer Security Courses
The world's first in-repository developer security learning — secure coding, secure design, AI security, cloud, and fuzzing. Clone real projects, use your favourite tools, and learn where you actually work: in the repo.
On-Demand, Self-Paced and Hands-On
Learn by doing, not just watching. Secure code learning and every other course integrates into your workflow, so practice sticks — and so does the skill.
Clone, add, commit, push
No new tools to learn before you start. Our courses run on git, so you use the same editor, debugger, and workflow you use in your day-to-day development work.
Real-world inspired content
Real incidents, not acronym soup. Stories of how security bugs became nightmares make complex concepts easy to understand and hard to forget.
Bite-size learning
Every course is designed to be completed in under 60 minutes, so secure coding training fits into a busy sprint.
Attacks turn into unit tests
In each lab, attacker inputs become familiar unit and integration tests. Make the tests pass and you've proven the fix — and the skill.
Integrates with your workflow
Clone, debug, patch, and test real vulnerabilities with your own tools. The learning process feels as natural as building an app.
Relevant and up-to-date
Content built from in-field penetration testing experience, covering the secure coding issues that matter right now.
Build a learning path with SecDim MCP
The platform is very fun, it's a great resource for CWEs and looking at bugs from a defence point of view.
