Proton keeps your data secure in the age of AI

Proton says its end-to-end and zero-access encryption means no AI tool can read user emails, files, or passwords, and its documented security principles have not been loosened for AI. AI-written code goes through the same unified controls as human code, including mandatory human approval, required security scans, and least-privilege access for AI agents. Proton uses AI reviewers, continuous AI-powered code reviews, and non-public cyber models from OpenAI and Anthropic for threat analysis, which receive source code and threat intelligence only, never customer content.
