Agnitum Outpost Firewall Pro
Agnitum Outpost Firewall Pro development of domestic programmers and is the most preferred firewall ( firewall) among ordinary ordinary domestic users who almost never look at " Task Manager". Agnitum Outpost Firewall Pro more convenient to use and provides more extensive information about ongoing network events around your PC..
Easy to use and provides good stats about what's going on in the network but ease of use doesn't mean reliability/performance! Ease of use " Agnitum Outpost Firewall Pro"costs the user in overspending system resources and in some places in regular BSOD. So for example the combination NOD32 v4.0 + Outpost Firewall 2.x caused a regular BSOD, Outpost Firewall older ones are more gluttonous on system resources, and especially when downloading large files through a fast network connection and from servers with a good return!
Versions of " Outpost Firewall" above the 6th in which the process " acs.exe"when downloading large files over a fast network connection and from servers with a good return, it devours from 15 and before 50% system resources, and sometimes even higher! And it doesn't matter whether you set up rules or disable all additional features- devours system resources ( CPU+Memory) no matter what and even in idle state ( CPU 8-15%)!!! In version " Outpost Firewall 7.5"named" performance edition":)) "acs.exe"behaves less aggressively when idle, but the time it takes to download large files over a fast network connection and from servers with a good return is all one devours from 15 and up to 50%
Version " Outpost Firewall 4" not so gluttonous, but, there were often crashes when changing user accounts and not only! No offense to the company's programmers " Agnitum"but, they are still very far from such products as" Comodo Firewall Pro", "Comodo Internet Security" or " Checkpoint Firewall-1"! Like it or not, but Western developers are making great strides in the field software than domestic...
Comodo Firewall Pro
After long wanderings in search of the best firewall ( firewall) my choice finally settled on " Comodo Firewall Pro 3.14"which is unlike" Outpost Firewall"remarkably stops attempts of incoming connections and wildly does not devour system resources - in the idle state it consumes no more than 0-2% CPU and 3-4 MB. In addition, when completely turned off or falling " Comodo Firewall Pro 3.14"which is unlikely, there is no access to the network, which cannot be said about " Outpost Firewall".
The program is able to independently analyze each potential threat and, if necessary, issue an appropriate warning. Wherein " Comodo Firewall" Recognizes more than 10,000 different applications in various categories ( for example, “safe”, “spyware”, “adware”, etc.).
"Comodo Firewall" also has proactive defense, proactive defense includes HIPS ( Host Intrusion Prevention Systems) - a system for repelling local threats. The task of HIPS is to control the operation of applications and block potentially dangerous operations according to specified criteria.
Main characteristics " Comodo Firewall Pro":
- - Full permanent control and protection of your personal computer from Internet attacks, Trojans, hackers, malicious scripts and other unknown threats.

- - Control over software updates.
- - Real-time traffic monitoring gives you the ability to instantly respond to possible threats.
- - Simple, intuitive multi-language interface ( including Russian).
- - Free for home and other network users.
"Comodo Firewall Pro"by default, it does not provide statistics on all attempts to cut off incoming connections, but with the creation of certain rules and proper configuration, you can get these statistics. My choice is definitely in favor of " Comodo Firewall Pro 3.14"and I think that it will remain unchanged... Why exactly version 3.14, and not 4.x or 5.x? - Yes, because version 3.x contains the most basic functions without unnecessary "bells and whistles" and it is less demanding on resources than 4.x or 5.x?...
According to matousec.com, Comodo's products continue to take first place among test participants: http://www.matousec.com/projects/proactive-security-challenge/results.php
The truth in Comodo Firewall Pro"There are no such useful features as blocking active elements and the statistics are poor, but this disadvantage in favor of saving system resources can be compensated by the Firefox browser and the AdBlock" + "NoScript" plugins, and if necessary, we will collect statistics with other programs ...

The Internet is full of dangers and in most cases it is through the network that malicious applications penetrate the computer, and then, nestling, they themselves begin to transfer the personal data of an unsuspecting user to the network or use the computer to spread spam or as a proxy server.
Therefore, it is so important that a good firewall be installed on each computer, or, as they say, a firewall. In this short review, we bring to your attention seven best free firewalls: Ashampoo Firewall Free, PC Tools Firewall Plus, Emsisoft Online Armor Free, ZoneAlarm Free Firewall, Filseclab Personal Firewall Professional Edition, Outpost Firewall Free and Comodo Firewall. You choose.
Ashampoo Firewall Free
First on our list is free product Ashampoo Firewall Free. Like most programs developed by the company, this firewall has a convenient and colorful interface with support for the Russian language and a built-in settings wizard.
To use the program, you must go through a simple registration procedure on the manufacturer's website. At the same time, a free code will be sent to the user's mailbox, which can be used to register Ashampoo Firewall.
Immediately after installation, the wizard will offer, choosing one of two modes: “Simplified” and “Expert”. In most cases, it is recommended to use expert mode.
The program has five main modules or sections. In the “Rules” section, you can configure connection settings for programs using the Internet. Modules "Statistics" and "Journal" are purely informative. Here you can view data about all connections and events.
The “Configuration” module is intended for internal settings of the firewall itself. The "Utilities" section contains four additional tools, namely, a process manager, a utility for cleaning the Internet surfing history and a pop-up blocker.
Ashampoo Firewall Free works like this: when an application for which there are no set rules tries to establish a connection, the firewall notifies the user about this, offering to create a new rule for this program, that is, to allow or block its access to the network.
If this function is disabled (training mode), the dialog will not be shown, and all applications for which no rules have been set will be blocked automatically. You can also use the "Block all" option. In this case, the firewall will block all connections without exception.
PC Tools Firewall Plus
Next, we advise you to pay attention to an excellent firewall called PC Tools Firewall Plus. Simple, free, with Russian language support, this firewall is one of the most reliable and effective, according to numerous user reviews. PC Tools Firewall Plus protects the system from unauthorized data transmission by trojans, keyloggers and others malware, and also prevents them from penetrating the computer.
It also supports flexible network traffic management, creating your own rules, protecting settings with a password, hiding the presence of a PC on the network. The program is easy to install, does not require, as in the case of Ashampoo Firewall, registration and system reboot.
Connection parameters are configured manually. It is advisable to do this immediately after installing the program, since by default PC Tools Firewall Plus marks some applications as unverified and therefore may partially block their work. The firewall user interface has six main sections.
The "Applications" module is designed to manage applications and create rules for them. You can compile a list of checked ports and IP addresses in the “Profiles” section, and if you want to analyze network traffic, you can switch to the “Work” section. AT general settings you can adjust the level of protection, configure filtering, full screen mode, and set a password to protect PC Tools Firewall Plus itself.
Emsisoft Online Armor Free
Third on our list is a free firewall from Emsisoft GmbH called Online Armor Free. The program has a rather impressive set of protection tools against all kinds of network threats, as well as blocking malware using the Internet. Online Armor Free includes four main protection modules: firewall, web filter, proactive defense and anti-keylogger.
Firewall and web filter provide reliable protection against information leakage from the user's computer, as well as prevent attempts of unauthorized access to the system by malicious scripts.
The proactive defense module allows you to control the behavior of applications and, if necessary, restrict their activities.
Online Armor Free automatically scans the system for potentially dangerous applications and flags them accordingly. The firewall uses up-to-date online databases to determine the security level of the applications installed on the system.
Online Armor Free has a fairly simple and convenient interface with support for the Russian language.

Filseclab Personal Firewall Professional Edition is another free, convenient and very simple firewall. The program supports the creation of individual rules for programs using a step-by-step wizard, network access filtering, real-time viewing of connections, logging, traffic monitoring. Filseclab Personal Firewall reacts to attempts by "dubious" or new applications to open a connection with a pop-up window asking you to create an appropriate rule.
The program uses three main levels of security, each of which is marked with a corresponding color: green, yellow and red. In addition, for each level it is possible to create personal rules. Filseclab Personal Firewall has a fairly simple interface divided into seven sections.

In the Rules section, you can set rules for a specific application or domain.
The rest of the sections are informative. There is no Russian language in Filseclab Personal.
Outpost Firewall Free
The next firewall, Outpost Firewall Free, is perhaps one of the simplest and most undemanding firewalls on the system. In this respect, it is akin to the standard Windows firewall, which, as a rule, is constantly present in the system and does not show itself in any way :).
Outpost Firewall is a fairly easy-to-use program designed to protect against external intrusions, as well as unauthorized data transmission by applications installed on the user's computer. Unlike other firewalls, Outpost Firewall Free doesn't require much prior configuration.
The application supports monitoring of all incoming and outgoing connections, real-time tracking of software activity, extensibility using plug-ins. In the event of a threat or network activity of “doubtful” programs, Outpost Firewall will notify the user about this by offering to allow or block the application that has declared itself.
Outpost Firewall Free has a very simple, uncluttered user interface. Russian language, unfortunately, is missing.
However, this is not so important - the program is simple enough that even a novice user can figure it out. A few settings allow you to adjust the level of protection if necessary (up to completely blocking connections), as well as create exclusion rules for various programs and services.
Comodo Firewall
And finally, we suggest you briefly familiarize yourself with another free firewall, Comodo Firewall. This powerful, feature-packed program with an impressive set of tools comes bundled with Comodo Antivirus, Comodo Defense, and Dragon Web Browser, but can also be installed separately.
The firewall provides complete protection against hacker attacks, Trojans, malicious scripts, keyloggers and other types of Internet threats. The application supports monitoring of incoming and outgoing traffic, working with ports, hiding a computer on the network, controlling software and driver updates
To additional features firewall can be attributed to the maintenance of a detailed event log, integration into Windows Security Center, fast switching between modes (from the system tray), system protection during startup, detection of unrecognized files, viewing active processes and launching applications in a special sandbox (Sandbox).
With such a solid set of tools, Comodo Firewall has a simple Russian-language interface aimed at the inexperienced in network settings user. All tools and functions of the application are distributed among four modules, and each option has a corresponding description.
Plus, the program is equipped with a system of interactive dialogs (pop-up windows), written in an extremely simple and understandable language for a novice user.
Outcome
Choosing a good firewall can seem like a daunting task. And to make this job easier, let me give you some free tips. First, when choosing a firewall, pay attention to the opinion experienced users and software testers. As a rule, a really good firewall leaves a lot of positive feedback.
Secondly, a good firewall should not enter into unreasonable conflicts with system drivers, popular applications and antiviruses, and also be able to work with the Windows Security Center.
The presence of updated databases is also very desirable. In addition, a good firewall cannot be easily disabled from the Task Manager (this can be done with Filseclab Personal Firewall).
Thirdly, the firewall should not slow down the system in any way. For example, in this regard, the ZoneAlarm firewall seriously loses, because it is quite demanding on system resources and can slow down a weak machine.
Also, before the final choice, it is advisable to test the firewall using a special program 2ip Firewall Tester. Everything else, such as the presence of the Russian language, the convenience of the interface, external decorations is secondary.
