- 02Every leak described
A written description, tags and three dates for every leak. Unverified seller claims are flagged as such.
- 03Cleaned, not just collected
Searchable fields, de-duplicated credentials, and an estimate of how much of a combo list is invalid.
- 04Fresh

We looked up the domain of a global pharmaceutical company on the same day in the public lookup of one of the largest infostealer intelligence vendors, and in DarknetSearch.
- Leaked records that name the domain
- Not covered

Both lookups for the same domain on the same day, as shown on screen. The vendor’s paid product may show more than its public lookup. We do not name the company or the vendor.
Infostealers are one leak type
We also collect breaches, combo lists, SQL dumps, open databases and documents, and keep every record searchable.
Records, not rumours
This is leaked data. What is said or offered about a company, on forums, Telegram, Discord, paste sites and at data brokers, is covered separately.
