It is one of the world’s most powerful alliances. And yet most people have probably never heard of it, because its existence is a closely guarded government secret.
The “SIGINT Seniors” is a spy agency coalition that meets annually to collaborate on global security issues. It has two divisions, each focusing on different parts of the world: SIGINT Seniors Europe and SIGINT Seniors Pacific. Both are led by the U.S. National Security Agency, and together they include representatives from at least 17 other countries. Members of the group are from spy agencies that eavesdrop on communications – a practice known as “signals intelligence,” or SIGINT.
