Currently Guardian Firewall is only available on iOS and iPad. Our founders are experts in iOS, and so this was development step one, but you can rest assured we are in the process of expanding our platform support. We are currently working on implementing support for Android devices as well as a native macOS app. Please stay tuned for exciting announcements when these platforms are live.
With increasing interest in using one security application across multiple devices and platforms, we are exploring a roadmap of development that would include many platforms including Windows devices as well, for users to protect their information across all of their devices. Official announcements can be found on our Twitter account @guardianiosapp.
