Best Firewall Apps Android

android

A firewall is a piece of software which screens network traffic. This software allows/blocks network connections based on a set of rules. When you think of a firewall, most likely your personal computer will come to mind. However, this type of software is available and necessary for your Android devices as well.

In the context of an Android device we will be focusing on the control of network connections to/from the internet on your Android device.

Firewalls are important not only for security — they prevent unwanted and potentially dangerous connections — but they are also effective at saving data. With our mobile devices, many of us have an accompanying data plan.

Many apps run in the background consuming valuable data if your device is not connected to WiFi. Firewall apps on Android allow for persons to block apps from consuming data in the background. Saving data ultimately means saving money which is awesome.

With the importance of firewall apps in our minds let us now look at some of the best Android Firewall apps available. You will be pleased to know that these apps do not require your devices to be rooted in order to work.

LostNet NoRoot Firewall

LostNet NoRoot Firewall gives users several options for customizing the flow of their network traffic. LostNet routes your internet connections through its firewall and the app makes sure that your data is kept safe.
