Senior🎓
Top SchoolClaudio Contin is a security-focused technologist and co-founder with over a decade of hands-on experience in penetration testing, red teaming and secure development, built on a prior 20-year background in web technologies. He has led developer and security teams for startups and Silicon Valley firms, delivered secure coding and Active Directory trainings, and presented original research at conferences including Defcon and Black Hat.

Service Worker abuse and BeEF persistence modules), making him equally comfortable discovering novel attack paths and helping organisations harden systems.
