Secure Mobile Apps
To achieve our goal of a comprehensive, privacy- and security-focused communications solution, Guardian is driven both by internal development and the open-source community at large. In cases where a viable, vetted, and usable product already fills the communications needs of our target audience, we will recommend apps that work.

Secure Messaging Scorecard
Which apps and tools actually keep your messages safe?
In the face of widespread Internet surveillance, we need a secure and practical means of talking to each other from our phones and computers. Many companies offer “secure messaging” products—but are these systems actually secure? We decided to find out, in the first phase of a new EFF Campaign for Secure & Usable Crypto.

Protect My Privacy
Protect My Privacy (PMP) lets you protect the personal information on your iPhone. It provides a layer of security between apps and the operating system, thereby giving the control back to the user. When an app attempts to access any protected information, an alert is shown and you have the option to “Protect” or “Allow”. The software is unique in that rather than merely blocking access to the information, which could cause the app to have unexpected behaviour or even crash, PMP instead supplies fake replacement information, such as randomized contact names, or a location specified by you. You can quickly switch between real and fake information, even while the app is running. PMP also provides automatic protection using crowd-sourced recommendations, this uses information from previous manual decisions made by other users for the same app.
