PRISM Surveillance Program
The NSA's program that obtained direct access to the servers of major American technology companies to collect foreign intelligence targets' communications.
OVERVIEW
PRISM is a clandestine mass surveillance program operated by the NSA that collects internet communications from nine major U.S. technology companies: Microsoft, Yahoo, Google, Facebook, PalTalk, AOL, Skype, YouTube, and Apple. First revealed by Edward Snowden in 2013, PRISM allows the NSA to directly access company servers to collect stored communications and data in real time. The program operates under Section 702 of the FISA Amendments Act, which was reauthorized most recently in 2018. The companies named have disputed the scope and nature of their cooperation while acknowledging compliance with lawful government data requests.
