EFF
acronymprivacyhacking
Stands for: Electronic Frontier Foundation
The nonprofit defending civil liberties in the digital world - and the maker of Certbot.
Founded in 1990, the Electronic Frontier Foundation litigates, lobbies, and builds: it was a founding partner of the effort that became Let's Encrypt, and it ships Certbot, the client that made free certificates operationally trivial. Its research and scorecards (device privacy, data practices) are standing references in privacy engineering.
