TheGuardian Project is a global collective of software developers, designers, advocates, activists, and trainers who developopen-source mobile security software and operating system enhancements.^[2] 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.

Guardian Project was founded by Nathan Freitas in 2009 inBrooklyn, NY.^[4][5][6] Since it was founded, Guardian Project has developed more than a dozen mobile applications forAndroid andiOS 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 theElectronic Frontier Foundation'ssecure messaging scorecard, along withCryptocat,TextSecure, "Signal /RedPhone",Silent Phone, andSilent Text.^[7] "Jitsi + Ostel" scored 6 out of 7 points on theElectronic Frontier Foundation's secure messaging scorecard. They lost a point because there has not been a recent independent code audit.^[7]

In March 2016, Guardian Project announced a partnership withF-Droid andCopperheadOS with the goal of creating "a solution that can be verifiably trusted from the operating system, through the network and network services, all the way up to the app stores and apps themselves".^[8][9]

Guardian Project has received funding fromGoogle,UC Berkeley with theMacArthur Foundation,Avaaz,Internews,Open Technology Fund,WITNESS, theKnight Foundation,Benetech, ISC Project and Free Press Unlimited.^[10]

Through work on partner projects likethe Tor Project, Commotion mesh and StoryMaker, the Project has received indirect funding both from theUS State Department (through theBureau of Democracy, Human Rights and Labor Internet Freedom program) and from theDutch Ministry of Foreign Affairs (throughHIVOS).

• Orbot: ATor client for Android. Tor usesOnion 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.^[11] Often Orbot is installed with orWall,^[12] an app which takes the lead on thefirewall and then add the requirediptables rules fortraffic shaping in order to allow Orbot traffic, and force the selected applications to beredirected to the Orbot TransPort. Instead of Orbot, AFWall+, available onF-Droid andGoogle Play app repository, is an alternative choice recommended forre-routing outbound traffic back through the local Tor port, even with iptables rules,^[13] and with avirtual private network likeOpenVPN. Finally, NetCipher SDK is the app developed by Guardian Project for users interested in enabling theirs apps working directly with Orbot (and thus with Orfox Tor browser).^[14]
• ObscuraCam: A secure camera app that can obscure, encrypt or destroy pixels within an image. This project is in partnership withWITNESS, a human rights video advocacy and training organization.^[11]
• Haven –free andopen-source Android security application designed to monitor activity happening around a device using its built-in sensors, and to alert the device owner of such activity. Co-developed withEdward Snowden under the auspices of theFreedom of the Press Foundation.^[15]

• Orfox: A mobile counterpart of theTor Browser. Guardian Project announced the stable alpha ofOrfox on 30 June 2015. Orfox is built fromFennec (Firefox for Android) code and the Tor Browser code repository, and is given security hardening patches by the Tor Browser development team. Some of the Orfox build work is based on the Fennec;F-Droid project.^[16] In Orfox, the project removed theWebRTC component,Chromecast connectivity, app permissions to access the camera, microphone, contacts (address book), location data (GPS et al.), and NFC.^[16][17] Orfox was to supersede the Orweb browser project,^[16] and has in turn been superseded by the Tor Browser for Android.^[18]
• Orweb: A privacy enhanced web browser that supports proxies. When used with Orbot, Orweb protects against network analysis, blocks cookies, keeps no local browsing history, and disablesFlash to keep the user safe.^[11]
• Ostel: A tool for havingend-to-end encryptedVoIP calls.^[19] This was a public testbed of the Open Secure Telephony Network (OSTN) project, with the goal of promoting the use of free, open protocols, standards and software, to power end-to-end secure voice communications on mobile devices, as well as with desktop computers.^[11] This was discontinued in 2017.^[20]
• ChatSecure: An instant messaging application integrated with theOff-the-Record encrypted chat protocol. Formerly called Gibberbot,^[21] the app is built on Google's open-source Talk app and modified to support the JabberXMPP protocol.^[11] This app was discontinued in December 2016 and recommendedConversations app for similar user experience.^[22]

Guardian Project offers downloads of its apps fromGoogle Play,Amazon Appstore,Aptoide, directly from their website, and through anF-Droid-compatible repository.^[11][23] Direct downloads aresigned and can be verified with the developer's key.^[24]
