Live Web Security Code Review and Secure Coding Trainings
PentesterLab regularly hosts in-person and online code review and secure coding trainings, deep technical sessions designed to elevate your team’s understanding of vulnerabilities and code-level security. Find out when we’re next available!
> VIEW UPCOMING SESSIONSAt PentesterLab, we don’t just teach you how to hack, we ensure you deeply understand vulnerabilities at the code level, building the expert knowledge you need to confidently tackle complex, real-world challenges.
🔍 Mastery Through Manual Exploitation
Hands-on beats theory. Our labs require you to manually exploit each vulnerability, so you understand exactly how it works—not just that it works. When you've done it yourself, you remember it.
🛠️ Build Your Own Tools
Off-the-shelf tools only find what they're built to find. Learn to write your own scripts and tools—you'll gain deeper insight into how attacks work and complete control over your testing approach.
📖 Go beyond Tools and Checklists
Learn to read source code, review fixes, and spot subtle implementation bugs that scanners, checklists, and cheat sheets often miss.
📼 Guided Learning with Expert Videos
Our labs are paired with detailed video walkthroughs. No hunting for tutorials or second-guessing sources. Just expert-led instruction you can trust.
📈 Clear Progression from Beginner to Advanced
Start from the basics or jump to advanced topics. Our curriculum is structured so each exercise builds on the last, giving you a clear path from beginner to expert.
🤝 Trusted by Top Security Teams
Trusted by world-class pentest, red, and AppSec teams. Learn the same skills these professionals use daily to secure critical applications against advanced threats.
🧑💻 In-Depth Code Review Training
Spotting vulnerabilities in source code takes practice. Our code review content shows you how to find issues across languages and frameworks, with videos that break down real examples.
🧪 Understand Why Payloads Fail
Running a payload is easy. Understanding why it failed, how to debug it, and what to try next is where the real learning happens.
