Computer security and the lack of computer security is a fundamental issue that underpins much of how the Internet does (and doesn't) function. Many of the policy issues that EFF works on are linked to security in deep ways including privacy and anonymity, DRM, censorship, and network neutrality.

EFF works directly on a wide range of security issues including increased deployment of cryptographic protocols through projects like HTTPS Everywhere and Certbot; improving the security of those protocols with the SSL Observatory; offering legal assistance to researchers through our Coders' Rights Project; offering practical security advice to activists through the surveillance self-defense project; directly auditing open source codebases; and working on the development of new security standards.

They poured in from all over the country: educational nonprofits, legal groups, libraries, activist networks, newsrooms, scientist groups, religious organizations. There are a few reasons for this rise...

Surveillance Battles: 2017 in Review

If you’ve been following EFF’s work, you’ll know that we’ve been fighting against the creeping surveillance state for over 20 years. Often, this means pushing back against the National Security Agency’s dragnet surveillance programs, but as new technology becomes available, new threats emerge. Here are some of the biggest legislative...
