1. Comodo firewall
My favorite personal feature Comodo offers is his mode "Sandbox". You can sandbox any program that will run the program in isolation mode so that any attack or violation of this program does not infiltrate the rest of your operating system.
Apart from this, you can easily allow / block certain applications to access the internet. The ease of adding programs to this list is also commendable.
Shows you how reliable a program is thanks to its Rating Rating feature. The only problem is that if you are a victim of exploitation attacks, Comodo is rendered useless.
Includes a browser cleaning feature as well as a game mode for better performance.
Advantages:
- Sandbox Mode.
- Kill
- Easy blocking / unblocking of Internet access.
- Analysis of evaluation
- Automated Alerts.
The inconvenients:
- Helpless against Exploit attacks.
- Automatic installation of the search engine, unless disabled during installation.
2. OutPost
The best feature of OutPost is its built-in file and folder binder! Or, you can fall in love with its multilayer security protocols. You can actually customize each of the four security layers manually.
Also offers an integrated anti-leak module to prevent unwanted traffic from getting out. Also has a connection monitor that helps identify outgoing unwanted connections.
Its program activity tracking program lets you see which application is changing what's on your system. The interface is extremely easy to use.
Advantages:
- Easy to use.
- Lightweight
- Locker of files and folders.
- Four levels of security.
The inconvenients:
- The number of popups is overwhelming.
3. GlassWire
What at first attracted me to Glasswire, is a sophisticated interface and rich in graphics. (Yeah I like bright things!) It displays a list of programs and the exact hosts to which they are connected. If something seems suspicious, do not hesitate to close it.
It also stores alert information so that you can always go back and check everything that has made Glasswire suspicious. Then a network monitor monitors your WiFi and the connection of other computers.
This free firewall allows multiple profiles for different situations. Can also monitor, as well as adjust the use of bandwidth / allocation for various applications.
Advantages:
- Graphic interface
- Network Monitor
- Advanced locking mode.
The inconvenients:
4. small wall
A must-have especially for those who spend their days mainly on the Internet (who does not? Also for those who do not like to browse dozens of windows before their firewall is configured. And hey, if you have little space, it uses less than 1 MB of disk space!
Is not extremely rich in features. Displays instant, real-time alerts in a small minimized window so that everything you do is not interrupted. Allows you to select sites and applications on the whitelist that you think are safe And offers basic WiFi protection.
That's about it!
Advantages:
- Easy and quick to install.
- Extremely light.
- Basic protection.
The inconvenients:
- Is super low on the features.
5. Private firewall
Private Firewall is a forgotten but not fallen hero. The parent company is not working, updating, or probably not even remembering giving birth once. Ironically, it's still one of the best free firewall software.
It allows you to block or block applications and websites. The monitoring of the clipboard, the monitoring of the contents of the screen, the monitoring of the electronic mail are some additional functionalities offered. Suspicious websites are self-blocked.
Emails are also monitored. Provides an advanced level of analysis and monitoring of hosts.
Advantages:
- Extremely rich in features.
- Easy to use
- Port tracking available.
The inconvenients:
- Many "text" on the interface.
- Not available for Windows 10.
6. AVS firewall
If you have children, you will love AVS. Primarily for its parental control features that are missing from most other options on this list. You set the list of websites visited by your children, preventing them from "too much" to mature quickly.
You must choose which websites and IP addresses are allowed to connect to your system and which ones are not. Your registry is also protected, changes are also monitored. Double also as an advertising blocker. Set the security levels, as well as the control of applications connected or not connected to the Internet.
Advantages:
- Parental control.
- Registry monitoring.
- Levels of security.
The inconvenients:
- The installation process is not impressive.
7. Free Avast Antivirus
Avast is one of the most professional and established names in the industry. It offers a free version of its antivirus and firewall that you can use.
Some features include a sandbox mode for suspicious new apps, WiFi protection. It also has a Do Not Disturb mode that was previously the "game mode".
It also monitors application behavior and sends suspicious files to avast for detailed analysis. Also includes an intelligent analysis function.
Pro:
- Sandbox Mode.
- WiFi protection.
- DND mode.
- Multilayer security.
The inconvenients:
8. Zone alarm
We can say that the best free firewall with the most features in 2020 is on this list. For starters, its free cloud online backup (up to 5 GB) is impressive. It prevents the accidental loss, corruption or deletion of data!
Then, it offers a layer of public and wireless network protection. Not only a firewall, but also an antivirus. Has two modes, "Auto learn" and "Max Security". They basically look like an automated and simpler configuration (self learn) or more manual configuration and control (maximum security).
The "stealth mode" is an additional curtain for hackers and intruders. For US customers, it also has "recovery assistance" in case of violation.
Of course, other common features such as application control, network monitoring, etc. are also available.
Advantages:
- Online backup.
- Multilayer security.
- Advanced features.
The inconvenients:
9. Evorim
His "watch mode" is my favorite. Once activated, all applications require the consent of the user before they can access the Internet. It also prevents browsers, websites, and software from collecting or sharing telemetry.
Evorim also displays a list of all programs running on the system and allows users to set permissions for each of them.
The firewall also monitors the background activities of applications and notifies any suspicious transmission or activity. It can also be used simultaneously with an antivirus already installed on the system. Access rules can be set for both alphabetical website addresses and IP addresses.
Advantages:
- Monitoring mode.
- Zones (to grant identical permissions to multiple applications).
- Blocks bot networks, viruses, and background data.
The inconvenients:
10. Peer block
More than a firewall, it's a "blocking tool", as its name suggests. It allows you to download a list of IP addresses to ban. These may include sites, ads from certain countries or anything you want to block.
The interface is extremely basic, just download the list of IP addresses to ban and take care of the rest. This helps users protect themselves against unwanted incoming and outgoing traffic.
Advantages:
- Extremely light.
- Easy to use.
The inconvenients:
- There is no advanced protection.
