Switch to Protonmail Reason #46: Use open-source mail apps that can be independently inspected

Trust should be open to scrutiny when a service handles the most sensitive record many people keep.

Why this matters

Trust should be open to scrutiny when a service handles the most sensitive record many people keep. Privacy is easier to defend before this information is collected than after it has spread.

The protection

Proton says its apps are open source and independently audited.

Take action

Review published security information and keep apps updated. Auditability does not remove the need to secure your account and devices. Email protection depends on the route and settings. Ordinary mail involving outside providers is not automatically end-to-end encrypted, and email metadata is not universally hidden.
