Yes—Proton Mail can notify you when monitored email addresses appear in breach intelligence. Proton launched Dark Web Monitoring on April 22, 2024. It is available on paid Proton plans and reports matches in the Security Center, with the affected service, available breach details, severity guidance, and suggested next steps.
What Proton Mail Dark Web Monitoring does
Proton says the feature scans hidden parts of the internet for Proton Mail addresses that appear in illicit data markets. It combines Proton’s threat-intelligence datasets with information from Constella Intelligence and third-party reports about stolen data associated with Proton Mail addresses or Proton Pass aliases.
The service detects known leaked information after another company has been breached. It does not prevent that original breach and cannot guarantee that every dark-web posting will be found.
Who can use it and which addresses are covered
Dark Web Monitoring requires a paid Proton account. Proton’s current support documentation says you can monitor:

| Indicator | What Proton says it means | Priority |
|---|---|---|
| Red | A password was exposed as plaintext or protected with a weak hash such as MD5, or the breach otherwise requires immediate attention. | Act immediately |
| Orange | No password was leaked, or the password was strongly encrypted or hashed; other personal information may still be exposed. | Review and remediate promptly |
The exact fields depend on the breach data available to Proton. An alert is evidence that a monitored address is associated with reported leaked information, not proof that every item shown remains publicly accessible.
What to do when Proton says your password leaked
- Change the password on the affected service. Use that service’s official website or app rather than a link in an unexpected message.
- Change every reused password. A leaked password can be tried against email, shopping, banking, and other accounts.
- Turn on multifactor authentication. Prefer an authenticator app or security key where the service supports it.
- Review account activity. Check recent sign-ins, recovery addresses, forwarding rules, payment details, and active sessions.
- Watch for phishing. Breach data can make scam messages look convincing; do not disclose one-time codes or passwords.
When an alert says no password was exposed, still assess the other data listed—such as an email address or personal details—and be alert for targeted fraud.

How broad Proton’s monitoring is
Dark Web Monitoring is based on breach intelligence Proton has obtained or analyzed. It is therefore a notification service for known or reported exposures, not continuous surveillance of every hidden website. Proton’s launch announcement described future plans for Android and iPhone notifications, custom-domain monitoring, and optional recovery or external-address monitoring. Those statements were announced directions in 2024; the current documented capability is monitoring Proton addresses, Pass aliases, and up to 10 authorized custom addresses.

Is Dark Web Monitoring worth enabling?
For a paid Proton subscriber, enabling it adds a breach-alert workflow without requiring a separate monitoring account. Its practical value depends on whether the relevant address appears in data Proton can identify and whether you act quickly after an alert. It should complement, not replace, unique passwords, a password manager, multifactor authentication, and account-security reviews.
