Hardware Guide

January 2013: We recognize this page is quite out of date and are working to update it. While we don’t (yet) produce our own hardware, we do offer custom configured versions of off-the-shelf devices. We’re also often asked “which phone should I get?” or “which carrier should I choose?”, so we decided to gather that information here for you. If you would like more information on our custom configured Guardian devices, please contact us. [Read More]

Firefox Mobile: Privacy Enhanced

Fall 2016: We no longer promote the user of Firefox with add-ons, as the solution can be insecure still and easily misconfigured. Please use our new Orfox browser for Android, based on Tor Browser.   The latest releases of Firefox on Android are proving to be very usable, stable and an increasingly viable alternative to the built-in webkit browser. However, it unfortunately lacks the ability to manually configure proxy settings through any sort of standard user interface.

OnionKit for Android

https://github.com/guardianproject/onionkit This is an Android Library Project that provides multiple means to improve network security in mobile applications. The “Onion” name refers to not only the Onion Routing concept used by Tor (which provides anonymity and resistance to traffic surveillance), but also the idea of multiple layers of security that any application should utilize. More specifically this library provides: StrongTrustManager: a robust implementation of an TLS/SSL certificate verifier, that can be customized with any set of certificate authorities Proxied Connection Support: HTTP and SOCKS proxy connection support for HTTP and HTTP/S traffic through specific configuration of the Apache HTTPClient library OrbotHelper: a utility class to support application integration with Orbot: Tor for Android.
