Questions about Breach Monitor

Where does the breach data come from?

From public and vetted breach corpora, updated as new dumps are verified. We store only which of your addresses appeared where — never the passwords themselves.

Do I need to list every address?

No. You register the email domain and every address on it that appears in a breach is reported, including ones you did not know existed.

What should I do with a finding?

Reset the password on the affected accounts, enforce MFA, and mark the exposure reviewed so the history shows who handled it and when.

Where do alerts go?

Every tool reports through one alert hub. You choose per destination: email, Slack, a webhook, SMS or a Jira ticket — and Service Watch shows the same signals on one board.

Where is my data kept?

The tools run on AWS in the EU (Frankfurt), operated by adcore s.r.o., a Slovak company. A few services they rely on sit outside the EU — Stripe for card payments, Google for analytics after your consent, the threat-intelligence lookups behind Safe Check — and the privacy policy lists each one.
