Breach & Identity Exposure Check – Dark Web Self-Check

Your password is probably in someone's database already. The question is which one, and what still uses it.

The Breach & Identity Exposure Check searches the public breach and paste record for the addresses, passwords and domain you give it, then does the part free lookup sites never do: works out what the exposure actually means for you and what to change first.

What it checks

• Whether your passwords appear in known breach corpora — checked using k-anonymity, so your password never leaves your machine
• Public paste sites where dumped credentials and personal data get posted
• Certificate transparency records for your domain, which reveal subdomains and services you may have forgotten
• Reuse patterns that turn one old breach into a live risk across your other accounts
• An optional deeper breach-database lookup if you supply your own API key — and the report states plainly when that step was skipped rather than pretending it ran

What you get

• A written PDF report emailed back to you, typically within one business day.
• Every exposure rated Critical / High / Medium / Low, with an explanation of what a criminal could do with it.
• A visual exposure map showing where your information turned up.
• A prioritised list of which accounts to change, in what order, and which to close entirely.
• A "what was checked" appendix that states the limits of the scan honestly.
• Reporting built to CompTIA Security+ and PenTest+ practice standards.

Who it's for

Anyone who has used the same password twice, anyone whose email has been around for a decade, and business owners who need to know whether staff credentials are circulating.

Requirements

• Windows 10 or Windows 11
• Run as administrator
• An internet connection
• The email addresses and domain you want checked — they must be yours
• About 5–10 minutes

What this is not

QuickScan is detection and advisory only. It searches public records; it does not buy data, does not access criminal marketplaces on your behalf, never exploits a weakness, and changes nothing. It is not a certification, an audit or an attestation. For a full investigation, the report points you to ThreatVector's hands-on Dark Web Exposure Scan.
