The training helped me expand my knowledge and understanding of Burp Suite. I also realized that what I had learned through self-study was still quite limited. This training was very helpful to me as a QA because Burp Suite is a valuable tool for performing security testing and improving the overall quality of application testing. I will continue exploring this tool and learning more about its features and capabilities.

I really enjoyed learning about AI attacks and the tools out there to begin practicing and actively using for security testing. I took a lot of knowledge away which I didn't have at the beginning and the course met what I hoped it would be. My favorite part shown from the training was Comet Browser and was amazed at what it could do. Definitely something will be looking into more. Overall it was a great course and enjoyed learning all OWASP GenAI Top 10.
