Who needs a firewall for PC?
While any good anti-virus software can prevent apparent harmful activity on your computer, sometimes programs and applications can misuse their permissions to create unauthorized network connections, which can be used to collect user data from your computer.
Windows has a great built-in firewall, but did you know that there are completely free and alternative firewall programs you can install? That’s right, and many are easier to use and understand features and options than Microsoft built-in their operating system.
It might be a good idea to check whether the built-in Windows Firewall is disabled after installing one of these programs. You don’t need to create two defence lines together – it can actually do more harm than good.
You do not need to pay for a high-quality firewall because some of the leading cybersecurity companies produce free software that will protect your computer.
Here is our list of the best firewalls for PC (FREE)
1. Comodo Free Firewall
Comodo is an award-winning cybersecurity software house that produces a firewall for all versions of Windows from XP to Windows 10. The paid firewall contains a free alternative, which the company claims is the world’s # 1 free firewall.
In addition to blocking incoming connections, this software package will monitor your computer for persistent threats, with a constantly updated threat database. The screen real-time alerts you to discover risks. You will get the Sandbox environment for any new software you download to protect from hidden viruses. The system uses artificial intelligence to build a profile of normal operating behaviour on your computer so that it can block suspicious activity. You can choose to prevent certain applications from accessing the Internet while the program monitors all outbound traffic in addition to incoming data. Other features include a browser cleaning tool and game mode to enable interactive applications to work online.
The spirit of TinyWall’s development is that it should be unobtrusive. The program works all the time and appears as an icon in the system tray. Click the icon to display the system popup menu. This means that threat information is available on request. The good point is that you will not freeze your computer by overlaying when you are in the middle of something. However, on the downside, threat alarms are easy to ignore, which is dangerous.
As a free tool that’s supposed to be lightweight (takes up only 1MB of space on your hard drive), this firewall doesn’t have many features. You can add apps to the whitelist to prevent your important programs from being banned, but that’s about it.
3. Outpost firewall
You can no longer obtain this firewall directly from the company, but it is available from software distribution sites, such as Filehippo and Softonic.
You might be wondering why an abandoned firewall is on this list. He is here because he deserves to be. Agnitum has licensed its firewall to other security companies, so this is the firewall you get from other cybersecurity providers, including Sophos. Although Outpost Firewall Pro is no longer supported, the free firewall is still strong.
Excellent security tool features include a well-known automatic white list of well-known programs, an anti-leakage module that blocks suspicious outgoing messages, file and folder lock, ad blocker and web browser popups.
4. Glass Wire
GlassWire is a network monitoring software in addition to a firewall, and it’s free to use. This package is installed on Windows 7, 8, and 10. Operating systems Although this software will be ideal for a small business network, it is also marketed for home use. The firewall can be set up with many profiles to behave differently in each specific scenario. For example, you could have a home network setting and a public wifi profile.
In addition to blocking incoming connections, the suite enables you to monitor bandwidth usage, and clamp down on some applications to provide more bandwidth for major applications. Traffic management functions decrease to port number, program, and processing.
The screen is always on and keeps track of all activities on the computer, looking for anything suspicious. Like TinyWall, GlassWire firewall functionality is actually just the original Windows Defender management interface.
Privatefirewall is a Privacyware product. The company’s flagship product is ThreatSentry, a security system designed for business networks. The company is no longer interested in the special firewall and has not mentioned the product on its website.
In addition to being one of the best firewalls for PC in our list, this tool is a host-based intrusion detection system. It checks the log files on your computer for worrying events. It will also protect these log files from unauthorized change or deletion, a trick covering the path used by some malware.
Standard suite firewall features include whitelist and blacklist functionality, as well as content privacy controls such as turn off text copying and clipboard monitoring. Firewall interface is a popup context menu that you activate by right-clicking on the program icon in the system tray.
The tool will also monitor email activity, disable downloading of infected or blocked websites, and block internet activity from a specific address.
In the modern world, there is no reason to consider installing an independent personal best firewall for PC as the built-in Windows Firewall does half the job, and the firewall inside your security suite takes care of the rest. The computer aficionado has ended the one who carefully and lovingly chose each separate security component.
