Resources

We didn’t write everything here from scratch, and you shouldn’t stop here either. These are the guides and organizations the hardening series draws on and points back to — people doing this work more deeply and more continuously than a single site can.

Digital security

Electronic Frontier Foundation — Surveillance Self-Defense The deepest, most current reference for device and communications security. Every guide in our Harden series leans on it. If a setting or a legal claim here goes stale, EFF’s version is more likely to be current — check there first.

EFF The parent organization: digital rights litigation, policy advocacy, and technical research. If you want to understand why a protection works, or support the people building the next one, start here.

Access Now Digital Security Helpline A free, 24/7 helpline for activists, journalists, and civil society if you have specific reason to believe you’re being targeted by government-grade spyware or a sustained digital attack. help@accessnow.org.

Data brokers and opt-outs

Privacy Rights Clearinghouse Maintains a data broker registry and consumer-rights resources this project’s own opt-out dataset draws on and credits.

Yael Grauer — Big Ass Data Broker Opt-Out List An extensively researched, continually updated list of broker opt-out procedures. Also a direct source for our own dataset — see the credits in LICENSE-DATA.

California DROP tool If you’re a California resident, the state’s free Delete Request and Opt-out Platform covers many brokers in a single request — genuinely faster than going broker-by-broker.

Hardened operating systems

GrapheneOS A hardened, de-Googled Android build for people at sustained, serious risk — referenced in the Android guide.

Tails An amnesiac operating system you boot from a USB stick for a single sensitive task, then leave with no trace — referenced in the Windows guide.
