Double your impact on digital freedom!

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 Certbot; improving the security of those protocols; offering legal assistance to researchers through our Coders' Rights Project; offering practical security advice to activists through the surveillance self-defense project; and working on the development of new security standards.

These challenges come from laws...

A Tale of Two Cybers

Cyber, Cyber, Cyber. The word makes most technical people cringe but it’s all the rage right now in DC and other policy circles. The rallying calls are now familiar and the central pitch is that private entities and networks—the buzzword is “critical infrastructure”—should be strongly incentivized to “share” information...
