Biography
Fredrick "Flee" Lee is Reddit's Chief Information Security Officer, hired in 2023 to lead the company's privacy and security teams, reporting to chief technology officer Christopher Slowe. He succeeded Allison Miller in the role. Lee brought more than two decades of information-security experience drawn from financial-services firms and technology companies. Immediately before Reddit he was Chief Security Officer and head of IT at the payroll and benefits company Gusto, a role he held from 2019, and earlier served as head of information security at Square, the payments company now part of Block. His appointment came in a period during which Reddit had disclosed a series of security incidents, including a 2023 breach in which an employee was phished and internal data was exfiltrated, placing the platform's defences under scrutiny. As CISO he is the named executive responsible for Reddit's data-security posture.
