How it is built, by role
The same roles apply across the whole collection. Nothing in this block is specific to this site; what the site says about itself is quoted word for word below it.
- 1
Edge network
Visitors reach a site through an edge layer: a content delivery network with a web application firewall in front of it.
- 2
Application host
The edge talks to an application host that serves the site and renders its pages.
- 3
Data
What the pages show comes from a relational database or, for a site pre-rendered at build time, from data files built into its release.
- 4
Scheduled measurement
The collection measures its sites on a schedule: content dates and site health nightly, page counts read from each site’s sitemap weekly. Every reading is kept with its date. A site too large to re-walk is not re-measured, and shows no trend.
- 5
Public status feed
A monitoring panel sends a signed report on uptime, deploys and backups once a day, and the Operations page publishes it. A figure on this page that comes from that report says so.
In the site's own words
Each passage is copied unaltered from a page the site publishes, with the address it was taken from and the date we took it. We add nothing between them.
“Breach Census is a global, entity-centred register of confirmed cyber attacks and data breaches, built from published regulator filings, court records and company disclosures, with every confirmed incident backed by a citable source.”
“Public regulator filings, court records and company disclosures — HHS OCR, SEC EDGAR, US state attorneys general, the ICO, CNIL, the FCA and PRA, CourtListener, CISA KEV / NVD, and ransomware-group leak-site trackers.”
“Every confirmed incident, cost figure and regulator action shown on the site carries a citation back to a source document.”
“An incident's confirmed flag is only true when at least one event on it carries a self-report, regulator or court confirmation level — a bare claim or press report is not enough.”
“An organisation is only created or matched against a registry identifier — a US SEC Central Index Key (CIK), a UK Companies House number, or a Legal Entity Identifier (LEI) — or against a name that is globally unique across the register.”
“Where a name match is ambiguous (more than one live candidate survives), it is refused rather than guessed, and the row is queued for manual review instead of being attached to the wrong organisation.”
“Most sources — including the state attorney general portals, HHS OCR, SEC EDGAR and the ICO — are ingested on a daily automated schedule; a handful of sources run weekly.”
