The key role private companies play in National Security Agency surveillance programs is detailed in a top-secret document provided to the Guardian by whistleblower Edward Snowden and published for the first time on Friday.
One slide in the undated PowerPoint presentation, published as part of the Guardian’s NSA Files: Decoded project, illustrates the number of intelligence reports being generated from data collected from the companies.
In the five weeks from June 5 2010, the period covered by the document, data from Yahoo generated by far the most reports, followed by Microsoft and then Google.
Between them, the three companies accounted for more than 2,000 reports in that period – all but a tiny fraction of the total produced under one of the NSA’s main foreign intelligence authorities, the Fisa Amendents Act (FAA).
It is unclear how the information in the NSA slide relates to the companies’ own transparency reports, which document the number of requests for information received from authorities around the world.
Yahoo, Microsoft and Google deny they co-operate voluntarily with the intelligence agencies, and say they hand over data only after being forced to do so when served with warrants. The NSA told the Guardian that the companies’ co-operation was “legally compelled”.
