Download firewall program for android. Firewall for Android: types of applications and their capabilities

Absolute majority mobile applications for Android they require permission for network connections during installation. Many of them really need it for full-fledged work, while others use it only to download advertisements or for other, not always useful, purposes. Default operating system Android does not contain tools that would help regulate the network activity of applications. However, this problem can be solved using third party application called NoRoot Firewall.

The operation of this utility exactly corresponds to its name and will not raise questions for anyone who has encountered setting up any firewall in Windows. NoRoot Firewall notifies you when applications try to access the Internet and allows you to allow or deny the corresponding connection. Thus, you create a set of rules according to which programs installed on your device will gain network access.

In addition to global rules, you can, as you see in the right screenshot, set more subtle specific instructions for each program. Thus, it is possible to specify a list of addresses to which access is allowed or denied, and even the connection method for each connection. NoRoot Firewall also saves connection logs, so you can see at any time which application sent/received data and from where. NoRoot Firewall works by creating a secure VPN connection and, unlike many competitors, does not require superuser rights. It is distributed free of charge and is available for all devices running under Android control 4.0 and higher.
Download NoRoot Firewall for Android you can follow the link below.

Developer: Gray Shirts
Platform: Android 4.0 and higher
Interface language: Russian (RUS)

Android security works a little differently than PC security. This means you don't need a firewall on your Android device, just like your PC. Power Management Features Android phone operate in such a way that it is not always open to traffic. And that you are unlikely to be able to receive malicious messages from the Internet (or make calls to the Internet).

However, more and more applications require an Internet connection to background. And there are many malicious applications that send your data about you. Data that you would prefer to keep secret.

Android firewalls are great for gaining more control over how your phones communicate with an internet blocking app. IP blocking, bandwidth control, etc.

Here are three best apps Android Firewall Tools You Can Use in 2019.

NetGuard

Functioning as a partial VPN, firewall, partially controlling applications, NetGuard. This affordable way Maintain close control over your phones' Internet connection.

It has its own built-in VPN. It must be activated before you can decide which applications can access the Internet and which cannot. Or they simply block web access to applications.

It's very easy to use, with Wi-Fi and mobile data icons next to the apps. Allows you to instantly touch them to turn the online connection on and off across both connections.

There are a few more things you can do. Such as blocking ads and logging exactly when your phone connects to the Internet in the background. This is especially convenient for those who like to keep things simple.

NetStop Firewall

Even if NetGuard isn't your thing, how about this: a giant red button that you press to block all internet-connected apps on your device.

Large kill switch network activity than a firewall. And it is undoubtedly effective.

AFWall + (Root required)

If you've rooted your phone, then one of the benefits is that you can really go deep into controlling everything on it. Including web traffic.

As with other firewall apps, AFWall+ has the usual list of apps. In it you can see which applications are “calling” home. And act accordingly.

The good thing here is that it doesn't need to tunnel your connection through a VPN to work. But if you are connected to a VPN, it will continue to work just as well. The firewall is based on iptables. This means that it works at a deeper level of your Android OS to monitor internet traffic. This also means you get the same level of control as with other firewalls. But you get the opportunity to maintain maximum Internet speed.

In addition, as proof of reliability, it is worth knowing that it was made by one of the developers on XDA. And has good followers from knowledgeable people.

Conclusion

There may not seem to be too many options presented above. But rest assured that they are the best you can get. Once popular firewalls such as LostNet Firewall and NoRoot Firewall have either disappeared or become unusable. These are your safest firewall bets in 2019!

How to prevent surveillance mobile phone/ Android smartphone?

Recently, one sweet girl wrote to us in the VKontakte group. She politely introduced herself and asked us to help her. The problem was this. The girl found out that her ex was following her. She, of course, has little understanding of computers and the word “” brings the same fear and misunderstanding to her as the terrible word “Scrub” does to me.

• Background
• Briefly what is a Firewall?
• Installing the Firewall application without Root
• Setting up the Firewall application without Root
• Using the Firewall app without Root

I helped her with the computer remotely via TeamViewer, it was installed on the computer old version. But it turned out that she was also being monitored using her phone. The most interesting thing is that the Anti-Virus for Android installed on her did not find anything suspicious. Then I decided to do something differently, not to remotely look for a needle in a haystack, but to install a firewall/firewall for it and cut off everything suspicious that tried to knock on the network.

Z Protecting an Android phone remotely is difficult. Rooting the phone was quite problematic, and not safe when it comes to ordinary users; we have already talked about the consequences of Root in terms of security in the article “”.

Therefore, my choice fell on a free firewall, which does not require root rights to work. By the way, a couple of years ago there was no firewall for Android that did not require root access.

Firewall for Android without Root

A few words about the terms used in this article. In human language about what a Firewall / Firewall is. A firewall is a program that allows you to filter all outgoing and incoming traffic. And traffic is data that passes through networks from a computer or smartphone to a website, or between them.

Firewall without Root: Installation

First, let's download the application. You can download Firewall without Root for free using this direct link from Google Play.

Click on the “Install” button.

One cannot but rejoice at the fact that the application does not require special permissions, and this, friends, is a very good sign.

Click on the “Accept” button.

After the application has been downloaded and installed, click on the “Open” button

The application is installed. You can launch the application by clicking on the “Open” button, but it is better to close all windows and restart the device.

Firewall without Root: Settings

After the reboot we will see this window. In which we are offered to launch the application. Before starting, I recommend checking the box “Automatically enable...”

After startup, a system warning window will appear. We read and boldly click on “OK”. Later I will explain what this means.

Second after the " Home", in which we launched the application, there is a tab " Pending access" On this tab you can see all the applications that are trying to connect somewhere from your device. Why somewhere? Because each application connects and sends information to different servers.

Every time some new or installed application for which there is no previously created rule in our application tries to send information or tries to connect to remote servers, you will see an alert on this tab.

Now it's up to you to decide whether, for example, it will work Chrome browser or not. What you consider trusted - allow, what is not - prohibit. Anything that you don’t think should have access to the Internet should be disabled. For example, you don’t use the camera, then feel free to turn it off. Or, for example, a photo album, a music player, all these applications have nothing to look for on the Internet, so feel free to prohibit them.

For example, recently I needed to write down phone conversation. As you know, Android does not have a pre-installed application; I had to look for it in Google Market. I installed a dictaphone, but from the very first minute it started trying to send something somewhere. Turning on the logic, I decided that he has nothing to do on the Internet, this is a local application, this is not Skype or Viber and he just needs to record the conversation mobile communications, and ended up turning it off. On this moment The application works great without internet access. If there is a need to update it, I will do it through Google Play, which by the way I allow access only when it is necessary to update installed applications.

On the " Programs", you can see all installed applications and the rules for them. Next to each application there are two empty fields (squares).

• The first is access to the network via WiFi.
• The second box is access via mobile network.

By clicking on each of them the user can set settings. Enable or disable network access. You can block a particular application selectively. To save traffic, you can, for example, block YouTube or other power-hungry applications by blocking only the Wi-Fi field. It can be very useful function in terms of traffic savings.

Tab " Global rules» offers to manually block a particular resource by IP or name. This could be some kind of website or some kind of left-handed Chinese server, on which Chinese non-name smartphones and tablets so often knock (lead information).

Well, the last tab “ The event log" Here you can see everything that is currently happening on the network. All applications that interact with the network in real time. Looking here, you will be surprised when you see that your phone is constantly sending something somewhere.

The program marks all allowed applications in green, and blocked ones in red. Information about the remote IP and the exact time of the event are also provided.

Firewall without Root: Use

My friends, the Firewall without Root described in this article is an application that must be installed on your Android device, smartphone and tablet. Also s Android phone protection can be improved by another similar application such as DroidWall, but it requires Root.

From today, only you can decide what is on your phone, where and when it connects, what is leaked and what is downloaded. The method described in the article does not provide a 100% guarantee, but it greatly improves the protection of the phone.

We continue our review of firewalls (or firewalls, if you prefer) for Android. In the last article we talked about the Gray Shirts studio program, as well as its direct competitor – Mobiwol. Exactly latest application and became the leader based on direct comparison. The new material will find out whether there is a worthy replacement for them.

advertising

First, let's introduce the experimental subjects. The first to come to our attention is AFWall+, a firewall that requires root access and offers (presumably) more than others. What sets it apart from its competitors is the ability to control traffic local network, DroidWall rules import, task scheduler support and much more. It is clear that such a solution is designed for experienced and sophisticated users.

And the review will end with LostNet, which, among other things, offers a paid Pro version. But do we need to pay extra and what benefits do we get? Perhaps there is no need to fence the garden if there is a universal Mobiwol? This will become clear after the review.

The test equipment used was:

• Tablet DEXP Ursus 8EV2 3G (Android 4.4.2, MT8382 processor, 4 x Cortex-A7 1.3 GHz, Mali-400 MP2 video core, 1 GB RAM, 4000 mAh battery, 3G module, Wi-Fi 802.11b/g/n );
• Smartphone Homtom HT3 Pro (Android 5.1 Lollipop, MT6735P processor, 4 x Cortex-A53 1.0 GHz, 64-bit, Mali-T720 video core, 2 GB RAM, 3,000 mAh battery, 4G module, Wi-Fi 802.11b/g/ n).

Android devices and most applications for them are focused on using the Internet. On the one hand, this provides extensive opportunities, on the other – vulnerabilities, ranging from traffic leaks to virus infection. To protect against the second, you should choose an antivirus, and firewall applications will help solve the first problem.

An advanced firewall that does not require not only root rights, but also additional permissions such as access to file system or rights to make calls. The developers achieved this by using a VPN connection.

Your traffic is pre-processed by the app's servers, and if there is suspicious activity or overruns, you will be notified. In addition, you can prohibit individual applications or individual IP addresses from accessing the Internet (thanks to the latter option, the application can also replace an ad blocker), both separately for Wi-Fi connections and for mobile internet. Creation of global parameters is also supported. The application is completely free, without advertising and in Russian. There were no obvious flaws (other than a potentially insecure VPN connection) found.

AFWall+

One of the most advanced firewalls for Android. The application allows you to fine-tune the built-in Linux utility iptables, adapting selective or global blocking of Internet access to your use case.

Features of the program are color highlighting system applications in the list (to avoid problems, system components should not be prohibited from accessing the Internet), importing settings from other devices, maintaining a detailed statistics log. In addition, this firewall can be protected from unwanted access or removal: the first is done using a password or PIN code, and the second is by adding the application to the device administrators. Of course, there is a choice of which connection to block. Disadvantage - some of the features are available only to users with root rights, as well as to those who purchased the full version.

NetGuard

Another firewall that does not require Root to function properly. It is also based on filtering traffic through a VPN connection. Is different clear interface and tracking protection capabilities.

Among the available options, it is worth paying attention to support for multi-user mode, fine tuning blocking individual applications or addresses and working with both IPv4 and IPv6. We also note the presence of a log of connection requests and traffic consumption. An interesting feature is the Internet speed graph displayed in the status bar. Unfortunately, this and several other features are only available in the paid version. In addition, the free version of NetGuard contains advertising.

Mobiwol: Firewall without root

A firewall that differs from its competitors in a more friendly interface and wide possibilities. The main feature of the program is a false VPN connection: according to the developers, this is a bypass of restrictions on working with traffic without using root rights.

Thanks to this loophole, Mobivol provides full control over the connection of each application installed on the device: you can limit both Wi-Fi communication and the use of mobile data, White list, include a detailed event log and the amount of Internet megabytes spent by applications. Additional features include highlighting system programs in the list, displaying software running in the background, as well as viewing the port through which a particular software communicates with the network. All functionality is available for free, but there is advertising and there is no Russian language.

NoRoot Data Firewall

Another representative of firewalls that can work without root rights. Just like other representatives of this type of application, it works thanks to a VPN. The application can analyze traffic consumption by programs and issue a detailed report.

It can also display consumption history over an hour, day or week. Of course, the functions familiar from the applications described above are also there. Among the features characteristic only of NoRoot Data Firewall, we note advanced connection settings: temporarily restricting access to the Internet for applications, setting domain permissions, filtering domains and IP addresses, setting your own DNS, as well as a simple packet sniffer. All functions are available for free, there are no ads, but some may be wary of the need using a VPN. At the moment, the application has been removed due to blocking access to the Internet even Google services, but downloads and installations are still available from third-party sources.

Kronos Firewall

A “set it, turn it on, forget it” solution. Perhaps this application can be called the simplest firewall of all those mentioned above - minimalism in both design and settings.

A gentlemanly set of options includes a general firewall, inclusion/exclusion of individual applications from the blocked list, viewing statistics of Internet use by programs, sorting settings and an event log. Of course, the functionality of the application is ensured through a VPN connection. All functionality is available for free and without advertising.

To summarize, for users who are concerned about the security of their data, there is an opportunity to further protect their devices using a firewall. The choice of applications for this purpose is quite large - in addition to dedicated firewalls, some antiviruses also have this function (for example, the mobile version from ESET or Kaspersky Labs).
