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.
