Darknet / breach scan for proton email addresses
Regular scans of the darknet about proton email addresses (and SL aliases) to show breach information in Proton Sentinel.

While ProtonMail doesn't currently offer darknet scans directly, they are actively exploring ways to integrate such features into their security suite. For general breach awareness, you can use the free service "HIBP", which checks your email address against a massive database of known breaches. You can find it here: https://haveibeenpwned.com/.
For more comprehensive monitoring, consider services like Abine's DeleteMe or Experian's IdentityWorks. These services often cover dark web scans and additional privacy protection features. Additionally, you can find a comprehensive list of B2B data providers offering dark web monitoring and other security services here: https://www.globaldatabase.com/top-10-b2b-data-providers-in-2024
Remember, even with the best security measures, practicing good online hygiene like strong passwords and being cautious about what information you share online is essential for protecting your privacy and security.
