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.

The Last Mile of Encrypting the Web: 2023 Year in Review

At the start of 2023, we sunsetted the HTTPS Everywhere web extension. It encrypted browser communications with websites and made sure users benefited from the protection of HTTPS wherever possible. HTTPS Everywhere ended because all major browsers now offer the functionality to make HTTPS the default. This is due to...
