Reddit announced that Fredrick Lee has joined the company as Chief Information Security Officer, reporting to Chief Technology Officer Chris Slowe. Lee previously served as Chief Security Officer and Head of IT at Gusto, and earlier as Chief Security Officer at Square. He will oversee Reddit's privacy and security teams.

The company says the privacy and security teams Lee will oversee are responsible for identifying and mitigating risks and challenges around compliance, privacy and information security.

The company says Lee has more than 20 years of experience leading information security and privacy efforts globally at technology startups and major financial services companies. Cybersecurity Dive reports that Lee had served at Gusto since 2019, holding the chief security officer and head of IT roles, and earlier was head of information security at Square. According to the company, Lee holds a computer engineering bachelor's degree from the University of Oklahoma.

Cybersecurity Dive describes the company whose privacy and security teams Lee will lead as a social media company. In its proxy statement, the company describes itself as a Delaware corporation. The company says it has spent the past several years bolstering its safety and security efforts, expanding teams in those areas and reinforcing measures that protect the platform. The company says it launched a new Transparency Center and regularly shares its findings, updates and practices with its community.

According to Cybersecurity Dive, an outside hacker stole an employee's credentials in a phishing campaign in early February and accessed some company documents, advertiser information, a limited number of contacts and a limited amount of source code. Cybersecurity Dive reports that Allison Miller, the former CISO and VP of Trust, was originally announced in February 2021 and left the role in January.
