## Why this matters

A leaked address or password may be circulating before you notice suspicious mail. Privacy is easier to defend before this information is collected than after it has spread.

## The protection

Proton's Dark Web Monitoring can alert eligible users about discovered data associated with covered addresses and aliases.

## Take action

Review alerts promptly and change affected credentials. No monitoring service sees every breach. 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.
