Your mobile phone is one of your most valuable assets: it stores your personal information, pictures, and private communication.
It is no surprise that there are many threats to your privacy and security looming right around the corner in the information age.
Luckily, you can prevent this. A firewall app on your Android phone can significantly eliminate malware, viruses, and security threats.
This article will reveal the top 5 best Android Firewall applications you can download today from Google Play Store.
Before we show you our top picks for the best firewall apps for Android, let us first understand what firewalls are and how they work.
What Are Firewall Apps?
The firewall is a type of software that has been around since the 1980s. It protects users while they access the internet and provides their home network with security.
The way that the firewall protects users is by restricting unauthorized users from accessing your private network. Effectively, this allows a firewall to control network traffic across the internet.
Though initially designed for desktop computers, firewall apps for mobile devices are available today. Depending on what mobile device you have, you need to evaluate whether or not you need a firewall.
Do I Need A Firewall For Android?
You may not need Android firewall apps if you’re an Android user.
The android operating system is based on the Linux Kernel. This means it is secure against most viruses and malware by design – a feature that most Linux systems have.
That is not to say that getting a virus on your phone or downloading malware is impossible. For example, if you download an app from a third party, your phone may no longer be secure.
If you have one or more third-party apps installed on your phone, you should consider downloading a firewall app.
Another reason you may want to consider a firewall is if you run server-side processes on your Android device. If so, your Android device will handle incoming internet traffic. In that case, you need a firewall for security.
Does My Phone Have Firewall?
Android phones do not have a built-in firewall by default. So, unfortunately, if you want to set up a firewall, you must download one from the Play Store.
Once you have a firewall app downloaded on your phone, you can turn it on by starting the app and enabling the firewall connections. Remember that you must give the app permission to turn on the firewall.
Stick around, and we’ll reveal our picks for the best firewall apps for Android.
What Kind Of Connection Do I Need?
This question gets asked frequently, as different users have different internet connections.
Generally, as long as you have internet access, you should use Android firewall apps on all modern Android devices.
Most firewall apps for Android work on both mobile data as well as Wifi networks. Your data may not be secure if you’re on a public wifi network. On the other hand, mobile data users have nothing to worry about.
For support of different network protocols, check the individual page for each Android firewall app.
Why Does My Android Firewall Show Up As a VPN Connection?
If you’re using a firewall, you may notice that it shows up as a VPN connection each time you connect to the internet.
This is normal – some Android firewall apps use the VPN packaging module available on Android, which shows up as a VPN connection. This simple method allows firewall apps to access the internet without requiring root.
Despite the VPN icon appearing on your mobile screen, the firewall application does not send external data. So, effectively, there is no extra data usage. Such applications also do not interfere with personal data and are built for security, so there is no need to block them.
