The National Security Agency (NSA) is an intelligence agency of the Department of Defense.

The NSA is responsible for the collection and analysis of foreign communications and signals intelligence (SIGINT). It protects U.S. government communications and information systems by way of information security, cryptanalysis and cryptography.

It provides the Machine with a significant volume of raw data such as e-mails, telephone communications, video feeds and audio feeds (“Ghosts”).

This is sent in signals just above the Shannon-limit, as is revealed by Henry Peck, an NSA analyst working out of a listening station in NYC. Having noticed the names of the terrorists had been added to case files he wrote, Peck unwittingly discovered the Machine's operations and an ISA team was dispatched to kill him (“No Good Deed”).

At some point (possiblity before The Correction), John Greer and Samaritan took control of the NSA headquarters and used it as an operation center with 1,206 assets. With the help of the Machine, Harold Finch infiltrated the NSA headquarters an attempted to deploy the ICE-9 virus, but he was captured by Travers and Brought to Greer in the operations center. Greer takes Finch to a soundproofed room, where Samaritan attempts to kill both of them by sucking the air out of the room. Greer suffocates, but Finch managed to escape to deploy the virus to destroy Samaritan. Although the building's Faraday cage kept the Machine out at first, John Reese and Sameen Shaw were able to use a wireless modem that was confiscated from Edward Snowden to give the Machine a connection inside (“.exe”).
