These days a lot of hacking groups are active and our personal data is at stake. Thankfully, Android comes with some of the best security features there are. If that is not enough, you can easily download and install one of the best firewall apps for Android to keep your device safe from external, malicious interference. The best firewall apps for Android are not as robust as the ones found for PCs, but they do their jobs well.
I would like to point out that a firewall is not an antivirus. Sure, it can indirectly safeguard your smartphone or tablet from getting a virus but it is technically not an antivirus. Think of the firewall apps as an actual wall of fire made around your phone, it will burn anything harmful coming your way. The antivirus apps for Android are more like the police, though, they find and arrest nefarious bugs.
Note: The 5 Best Firewall apps for Android were tested on a Samsung Galaxy S7 Edge smartphone. The apps worked fine and didn’t drain almost any system resources. If you have root access to your device, some of the apps will work a lot better.
NetGuard is simple, yet effective way to block Internet access on your device. The best part is, you don’t even need access to block off malicious websites from the device. Addresses and even applications can be individually configured for access on the Android device.
There were a lot of features available that allow you to customize the experience you have with this firewall app for Android. For example, you can easily block when roaming.
You can also block system applications from accessing the Internet, this allows them to stay as it is and won’t receive any updates. I really liked the feature which allows you to record network usage per application so that you can track the ones using all your mobile data.Show Downloads
NoRoot Data Firewall
Just as the name implies, NoRoot Data Firewall is a great way to control how your device uses the Internet. The app allows you to easily manage all the apps and how they use your Internet. Even if you’re using mobile data or Wi-Fi, it will be quite easy to regulate the Internet usage of your device.
One great thing about this app is its ability to block background data usage and only let foreground data run freely. You’ll be able to analyze, record and start the data usage for each app and truly gain useful details about them. You can also set temporary permissions for one hour as well; this comes in handy when someone else is going to use your Android device.Show Downloads

You’ll be able to directly take control of the apps installed on your Android device with this app. With this app on your side, you can easily allow or block app connectivity.
If one of the apps has gone rogue and used a lot of background data, you can simply restrict its usage. You can also get alerts when a new app tries to access the internet. The app may not be as effective as dedicated battery saver apps for Android, but it works well in combination with them.Show Downloads
AFWall+ (Android Firewall +)
If you have a rooted Android device and want to get one of the best firewall apps for Android, AFWall+ is the best one you can get. The app has a very pleasant interface and works great on almost any device. The app is a front end application and comes with powerful iptables Linux firewall.
As it requires root access, the app is able to provide you with more options than the apps listed above. For example, you will be able to hide lock screen notifications with ease here. The app works faster and is a lot more reliable than the rest, a solid benefit for the rooted devices.Show Downloads
DroidWall – Android Firewall
DroidWall is perhaps the oldest and most popular Android firewall app available on the Google Play Store. The interface is barebones and resembles the old school Gingerbread interfaces, but that doesn’t mean the app is out of commission. It is still one of the best firewalls for Android in the market.
This app also requires root access, so naturally, it comes with a slew of advanced features. I only recommend this app to advanced users who know what they are doing. The app allows you to manually define custom iptables rules giving you a lot of power over your device. The app is almost the same as the one above in terms of features, though.Show Downloads
