How to Add a Firewall Protection on Android Smartphone

A firewall is, after all, the ultimate protection that saves your device against malicious programs by blocking all sorts of threat suspicious files. A reliable firewall further looks over your network security and stands as an ultimate shield for your device. Coming to Android, it seems like an open platform without any convenient protection from outer threats. But Apps such as NoRoot Firewall give an easy way to set up your personal firewall on your smartphone.

At such times, it becomes important to load up your Android smartphone with a reliable firewall that looks after the overall health of your device. But how do we do that? Since Android doesn’t offer inbuilt firewall protection, how can we add one to our phones? Don’t worry, you can check out list of the best firewall for Android you can choose from. But for this article, we will be using a free and easy to use the app to set up a firewall on your Android smartphone and use it efficiently.

Steps to Add a Firewall Protection on Any Android

First and foremost, as Android has no inbuilt firewall protection, the only way left is to use a third-party application. NoRoot Firewall does everything for you.

NoRoot Firewall – Features

NoRoot Firewall is the perfect solution to keep your Android phone safe and secured. It offers the following amazing features as a Firewall Protection app:

  • It requires no root access and works just fine, even with the latest Android update.
  • Instant access control based on IP/ hostname/ domain name
  • Controls outgoing/ incoming network connections.
  • Intuitive interface
  • Requires minimal permission
  • Allows global filters for each app
  • Allows to block specific IP/ Port for all or selected installed applications

Although this app’s features look pretty convincing, one thing to remember is NoRoot Firewall does not work on LTE Android smartphones since it doesn’t have support for IPv6 yet. We might see this feature too in the coming upgrades of the application. However, as of now, it offers a pretty decent and powerful service.

Besides, the application is lightweight and occupies very little space on your smartphone (size varies with device). It has a 4.2 rating on Google Play. NoRoot has over 5,000,000+ installs, and the app keeps getting regular updates, which is one of its impressive things.


And that is how you add your personal Firewall on your Android smartphone. NoRoot Firewall Protection is one of the best solutions when it comes to a reliable firewall for Android. It is quite easy to set-up and protects your personal data from getting leaked on the internet, and also acts as a shield for your phone. Above all, this application is trusted by many and is one of my personal favourites.
