NICO Waisman's career in cybersecurity began in Argentina where he self-taught hacking skills during a rebellious youth. He joined Immunity in 2003 as a security researcher, progressing to VP of Latin America, and learned leadership through forming teams of friendly hackers. In 2019, he transitioned to Semmle, which was later acquired by GitHub, focusing on securing open-source software. In 2020, he became the head of security at Lyft and, within two years, its CISO.
