Best Firewall Apps to Secure Your Android Phone - Explanations

NetGuard is one of the best firewall apps that offers advanced features like network stats, custom notifications, and rule backup. NetGuard uses a local VPN connection to filter internet traffic and allows you to block any app from accessing the internet over Wi-Fi or cellular data.

The best thing is that you can manage and create your own firewall rules for system applications. This means that you can easily control which system applications can connect to the Internet. Also, you can quickly reduce your mobile data usage and make it last all month with NetGuard.

Above all, this app works perfectly on non-rooted devices. While the app is free to use, you can make an in-app purchase to unlock more features like IP traffic logs, custom blocking rules, and different app themes.

 

Firewall No Root is a feature-rich firewall app with a clean user interface and is completely ad-free. Unlike other firewall apps, this app uses artificial intelligence, so it automatically blocks spy servers when they are detected. To start using this application, you need to select the default startup option: silent mode or warning.

Silent mode allows all connections, and you can block individual connections as required. If you are a beginner, we recommend that you select the silent mode. While warning mode allows checking which applications are silently connecting to an unsecured server. After selecting the warning mode, the firewall will prevent all applications and services from connecting to the Internet. Then, you can allow apps manually from the quick settings panel or in the app.

In addition, you can also configure the DNS servers provided by AdGuard, Cloudflare, Comodo Secure DNS, and more, and set a private DNS that works best for you.

AFWall+ requires root access, as it is an iptables based firewall. As such, it does not create a VPN like other firewall applications. In general, iptables-based firewall applications are more effective than other VPN-based applications such as NetGuard and NetProtector. But as it becomes increasingly difficult to root Android smartphones, it is often easier to use a VPN-based firewall app.

AFWall+ provides advanced control of your network connection and makes it easy for you to modify iptables. Iptable is a powerful Android firewall tool that allows users to create custom rules to control incoming and outgoing traffic.

This application also allows you to control the firewall rules across different connections such as roaming, VPN, and even LAN. If you are rooting your phone, you should use this app instead of other firewall solutions,After using the app for several hours, we found that AFWall+ doesn't consume much of your CPU, unlike other free firewall apps in the Play Store. This means that this app runs efficiently with low memory consumption and does not waste much battery power.

If you are looking for a simple ad-free firewall application, then Xproguard is for you. It offers few features compared to the other apps on our list, but the firewall rules work perfectly.

Xproguard creates a VPN connection and then diverts your internet traffic according to the set rules. Since you cannot connect to more than one VPN due to Android restrictions, you should not use this app with any other VPN app.

Since Xproguard is a VPN-based firewall app, you don't need a rooted smartphone to use it.
