Firewall App on Android: How it Works?

Before I move on to the topic, let me clarify what a firewall is. Firewalls monitor and control incoming and outgoing network traffic, saving us from tracing data as well as saving data.

Several decades ago, computers were protected by firewalls. When it was first released, mobile devices were not supported. However, the technology industry is growing rapidly, and everything is changing at an accelerated pace. 

In recent years, developers have found a place in this category and come up with excellent and easy-to-use firewall applications.

Apps like these basically implement a firewall inside your smartphone, allowing you to control all the apps and web content on your phone, so you can have some control over how your data is used.

Communication that attempts to cross it is filtered, resulting in only approved individuals being allowed access. 

Therefore, a firewall on your Android will help you filter out apps that can interact with the internet from those that can’t.
