Andy Yen, the CEO of Proton, had a message for an employee in the company’s security Slack channel who urged the company to at least take a few days to pentest newly written code before pushing it live. “That’s bullshit and loser thinking. Of course it’s possible to be fast and secure,” Yen wrote in the channel at the end of August. “Stop thinking always of how to be slower, and focus more on how to be faster.”

404 Media spoke to eight current and one former Proton employees and reviewed Slack chats, meeting recordings, and an AI manifesto written by the company’s CTO. Our reporting reveals a culture of fear inside Proton, where many employees are hesitant to even mildly critique Yen’s views or discuss engineering problems. Wor
