Proton Mail For Business vs. SendSafely

Proton Mail for Business is a secure email and calendar solution tailored specifically for small and medium-sized businesses (SMBs). This platform enables users to send, receive, organize, and manage professional email and calendar communications while ensuring built-in privacy and encryption. Designed to support critical business communication workflows, Proton Mail for Business protects sensitive information from unauthorized access and assists organizations in meeting data privacy and compliance requirements.

SendSafely is the end-to-end encryption layer for the platforms your business already runs on. Files and messages are encrypted in the sender's browser before they leave the device, and our split-key architecture means no single party, including SendSafely, can access content without authorization. One platform covers the full range of sensitive data exchange: Send & Receive — encrypted file and message exchange from the web app, Outlook, or Gmail. Recipients open with one click, no account required.
