Proton Mail for Business

Proton Mail for Business is a secure, enterprise-ready email solution designed to protect sensitive company communications. It uses end-to-end, zero-access encryption to ensure only intended recipients can read messages, and even Proton cannot access them.

Businesses can use custom domains, manage users through centralized admin controls, and enforce security policies across teams.

Advanced features such as anti-phishing protection, spam filtering, and secure calendar integration help streamline daily operations while maintaining compliance. Based in Switzerland and protected by strong privacy laws, Proton Mail for Business gives organizations full control over their data without sacrificing usability or performance.
