Arnau is among the top security researchers, with strong hands-on experience and deep technical expertise. His understanding of software protection and low-level programming is truly eye-opening. The course is exceptionally well structured, comprehensive, and technically rigorous.
I gained a tremendous amount of practical knowledge that I immediately applied to strengthening our codebase. The insights into numerous attack vectors were particularly valuable and broadened my perspective significantly.
Highly recommended.

The lectures by Arnau went very deep, while staying accessible for people without a formal math background. The exercise materials and projects were engaging and a natural practical extension of the theory discussed during the lectures. Arnau was also very responsive and happy to discuss ideas. Overall a superb experience and I highly recommend you attend one of his trainings!
