At its heart, the Guardian Mobile Firewall — currently in a closed beta — funnels all of an iPhone or iPad’s internet traffic through an encrypted virtual private network (VPN) tunnel to Guardian’s servers, outsourcing all of the filtering and enforcement to the cloud to help reduce performance issues on the device’s battery. It means the Guardian app can near-instantly spot if another app is secretly sending a device’s tracking data to a tracking firm, warning the user or giving the option to stop it in its tracks. The aim isn’t to prevent a potentially dodgy app from working properly, but to give users’ awareness and choice over what data leaves their device.

Strafach described the app as “like a junk email filter for your web traffic,” and you can see from of the app’s dedicated tabs what data gets blocked and why. A future version plans to allow users to modify or block their precise geolocation from being sent to certain servers. Strafach said the app will later tell a user how many times an app accesses device data, like their contact lists.

But unlike other ad and tracker blockers, the app doesn’t use overkill third-party lists that prevent apps from working properly. Instead, taking a tried-and-tested approach from the team’s own research. The team periodically scans a range of apps in the App Store to help identify problematic and privacy-invasive issues that are fed to the app to help improve over time. If an app is known to have security issues, the Guardian app can alert a user to the threat. The team plans to continue building machine learning models that help to identify new threats — including so-called “aggressive ads” — that hijack your mobile browser and redirect you to dodgy pages or apps.
