PANOPTICON INDEX

An educational index of the U.S. surveillance industry — 27 companies and 211 products, mapped to the agencies deploying them and the investors funding them. Built to make an opaque industry legible.

Methodology & sources

Data is compiled from public reporting and civil-liberties research — including the EFF Atlas of Surveillance, the ACLU, and investigative journalism.
Every claim carries a citation. Specific deployment claims should be verified against the cited sources before republication.
Foreign-based vendors are flagged; they are included where widely deployed against people in the United States.
