11 Best Firewall Apps For Android
If you peek in the PlayStore you will be bombarded with thousand firewall software, but all of them are not good. Some might also be more harmful then safeguarding the system. We have mentioned 11 best android firewall apps you may use on your smartphone, so let us dive into those.
1. NoRoot Firewall
As the name suggests you do not need root access to use the NoRoot Firewall. The app notifies you when an app is trying to access the Internet. All you need to do is just press the Allow or Deny button. You can also make filters depending on IP address, hostname, or domain name.
On the flip side, the app does not work on LTE connection as it does not have IPv6 support but the developer is trying to get a fix. Although the user interface is straight forward, the design is kind of old school.
NetGuard is a 100% open source software with no tracking, analytics, or advertisements. Unlike NoRoot Firewall it supports IPv4/IPv6 TCP/UDP connections. So if you are connected to an LTE network you are good to go. The user interface of the app is also much streamlined with modern material design.
If you get the pro version you will be able to allow or block individual addresses per application, select from five additional themes in both light and dark version, and much more.
If you are a power user and meed more value from your firewall you should check out AFWall+. The first thing to know is the software needs root access. So if your phone is not rooted, or you do not know about rooting much, this application is not meant for you.
Some of the extra features you will find here is Tor support, VPN support, LAN support and Tasker integration. Although the user interface could have been better.
4. NetPatch Firewall
NetPatch Firewall is another firewall that does not require root access. With all the regular features you will get options like creating domain and IP groups, blocking a specific IP address, and many more.
Known issues of the app are it does not support IPv6 only networks and as it does not have root access, VPN does not work with NetPatch.
5. NoRoot Data Firewall
The first thing to notice, NoRoot Data Firewall is not available in the PlayStore and you need to head to xdadevelopers to download it. From the application, you can monitor your data app by app basis and the interface is well thought out.
Some of the features of this app are already available in native android nowadays, like allowing only foreground app data consumption, and one known issue is it needs a bit more RAM than most of the other apps in the list.
6. Droid Wall
Droid Wall is available on the APKPure Appstore and it also requires root access. The app offers all the basic features you might need and with great reliability. Some of the best features of the application are custom shutdown script and manual control over custom IP tables rules.
One downside is the application has an interface straight from Android Gingerbread. So if you are into good UI, you might want to skip Droid Wall.
Mobiwol is one of the latest released firewalls on the PlayStore, so the interface is based on the material theme and easy to use. It can configure both incoming and outgoing traffics independently and the app also has settings to set different rules for each local network, mobile data, and WiFi.
Mobiwol does not require root access and after the latest update, the added a not removable notification icon for better stability.
8. Karma Firewall
Karma Firewall lets you take control back of your phone and block internet traffic to and from specific apps. This is a simple yet powerful firewall with an easy to use intuitive user interface which allows you to protect your sensitive data.
Karma Firewall is also available as Kronos Firewall in the APKPure Appstore and it does not require root access or internet access.
9. NetStop Firewall
If you are new to firewall software and do not want to fiddle much with all the settings, choose NetStop Firewall. On the main page, it only has a single button that will do all the magic for you.
The interface is a kind of flashy but old school and it also comes with some advertisements. But it does not temper with personal data or security by any means.
10. Protect Net
Protect Net is another firewall that does not require root. By far the app has the best user interface and usability. The app also does not eat up your battery. With all the necessary features it also supports IPv6 connections.
The app does not collect any personal information and if you doubt that, the developers are eager to provide the source project code of the software itself.
11. VPN Safe Firewall
Last but not least on the list is the VPN Safe Firewall. The software provides free and unlimited firewalls with WiFi, LTE, 4G, and 3G support. You can also record network usage per application and revoke access at any time.
The interlace is a bit cluttered for my taste but the better side is it does not require root access.
So these were all the best firewall application you can use to safeguard your internet experience on the go. Hopefully, you liked at least one of those, and if you have any more questions feel free to comment down below.
