If you want your Android to be protected, you have to know the best firewall to install on your phone for free.
There are many security tools and programs that can protect our devices. One of these options is known as the firewall. They help us to protect our equipment and avoid possible security problems that compromise its proper functioning of it. They allow us to restrict certain connections and we have more control. Today we are going to talk about the best firewall for Android. As we know, it is the operating system for most used mobile devices. Therefore, it can benefit many users to improve their security while surfing.
The best Android firewall apps to secure your Android phone and tablet devices
A firewall in Android, as in any other operating system, gives more control to users. We can control the communications of our phone on the Internet, block access to the network to certain applications, block IP addresses, or bandwidth. Here are the best firewall apps for Android that you can use. I also leave a link to Wikipedia where it explains very well, what is the firewall.
NetGuard (No-Root Firewall App)
NetGuard is one of the best Android firewall apps to keep tight control over your phone’s Internet connectivity. It has its own built-in VPN, which you must enable before taking control of applications that have access to the Internet and do not do so (or do not block web access to applications). It is very simple to use, with Wi-Fi and mobile data icons next to the apps, allowing you to instantly tap them to enable and disable online connectivity through both connections.
You can do a few other things, like blocking ads and accurately recording your phone’s connection to the Internet in the background, but it’s just as convenient for those who like to keep things simple.
NoRoot Firewall
This firewall has a very simple interface to use. Only when entering, it already asks you if you want to start the firewall or not. How does this firewall work? Make use of a VPN that you can control to restrict or authorize certain communications. When you hit “Start” for the first time, you’ll see that it asks you to access the VPN.
Once it is working, you will see many notifications of applications that try to access the internet from your smartphone. Within the “Pending Access” section we can allow or deny access to the network of applications that have requested it. If you do not see the application or do not want to wait, you simply have to go to the “Applications” section, find the one you want to block, and choose if you want to block it from WiFi, mobile data, or both.

Android Firewall +
If you have rooted your phone, one of the benefits is that you can really deepen control of everything, including web traffic. As with other firewall applications, AFWall + has the usual list of applications where you can see which apps are calling from home and act accordingly.
The good thing here is that it does not need to create a tunnel for your connection via a VPN but if you are connected to a VPN, it will continue to work just as well. The firewall is based on Iptables, which means that it runs at a deeper layer of your Android OS to control internet traffic. It also means you have the same level of control as other firewalls, but you maintain the highest Internet speeds.

Xprivacy
This application is one of the best travel companions for your smartphone. Because it is designed to intermediate in any process that requires a connection to the outside. You can block incoming or outgoing communications before they are even registered in the system’s permissions log, being able to configure them in detail thanks to its complete administration panel. A very important aspect considering that many of the attacks are given as a result of malicious applications that extract more data than they are originally authorized to take. The only downside is that you need to root your device to use this app.
