Overview
Proton Mail for Business is an encrypted email service designed for organizations that want to protect business communications without compromising privacy. Developed by Proton, it combines end-to-end encryption with business email features such as custom domains, administrative controls, and secure collaboration tools.
Beyond sending and receiving email, Proton Mail for Business helps organizations protect sensitive information through end-to-end encryption where supported, helping reduce the risk of unauthorized access to business communications. It also integrates with other Proton services, allowing teams to manage secure communication within a broader privacy-focused ecosystem.
