The Guardian Project is a global collective of software developers, designers, advocates, activists, and trainers who develop open-source mobile security software and operating system enhancements. They also create customized mobile devices to help individuals communicate more freely and protect themselves from intrusion and monitoring. The effort specifically focuses on users who live or work in high-risk situations and who often face constant surveillance and intrusion attempts into their mobile devices and communication streams.


History

Guardian Project was founded by Nathan Freitas in 2009 in Brooklyn, NY. Since it was founded, Guardian Project has developed more than a dozen mobile applications for Android and iOS with over two million downloads and hundreds of thousands of active users. It has also partnered with prominent open source software projects, activists groups, NGOs, commercial partners and news organizations to support their mobile security software capabilities. In November 2014, "ChatSecure + Orbot" received a top score on the

Tor uses Onion Routing to provide access to network services that may be blocked, censored or monitored, while also protecting the identity of the user requesting those resources. Often Orbot is installed with orWall, an app which takes the lead on the firewall and then add the required iptables rules for traffic shaping in order to allow Orbot traffic, and force the selected applications to be redirected to the Orbot TransPort. Instead of Orbot, AFWall+, available on F-Droid and
