  • DevSecLab hits the sweet spot in information security training for busy developers. Lessons are easily approachable on your own at your own pace, and exercises are complicated enough to keep things interesting. Good alternative or addition to traditional workshop-based training.

  • The public web is a hostile environment. Our whole team went through the DevSecLab, which kept us talking about security for months. The training gave us actionable insights on minimizing the attack surface of our software.
