Firewalls are software programs used to improve the security of computers. It protects a private network or LAN from unauthorized access. The purpose of installing a firewall on your computer, phone, or tablet is to protect against malware threats over the Internet or other connected networks. You don’t need to pay for a high-quality firewall as some significant cyber security companies produce free software that protects your computer. Here are the best free firewalls for 2022:
1. ZoneAlarm
ZoneAlarm Firewall is installed on Windows 7, 8, 9, and 10. Some great additions to this system make it an excellent option for WiFi networks and laptops that connect to the public areas Internet. Only you need an internet connection to download and an email address for activation to install it.
The firewall includes a “stealth mode” that protects your connection from hackers, provides identity protection services, and blocks malware.
The software will include an additional layer of security to your connection when you connect to a public WiFi hotspot. It assesses the security of your WiFi network to improve protection from attacks. It updates automatically, so you benefit from an up-to-date threat protection database.
2. TinyWall
TinyWall is designed with Windows’ built-in Defender Firewall, with minimal performance. TinyWall will actively block Trojans, worms, viruses, and other types of malware and prevent the modification of Windows Firewall settings by malicious programs. And it will do all this without you needing to know about port, protocol, or application details.
But its most significant feature is its no-popup approach. Most firewalls will display a popup asking what you want to happen whenever an application tries to access the Internet. Not only is it annoying, but eventually, you’ll end up giving access to everything to get rid of popups, which isn’t very secure.
TinyWall solves this problem by asking you to allowlist the programs you want to access the Internet. When you find that a program has been blocked, it’s easy to add it to the allowlist, and then you can continue with what you were doing.
3. GlassWire
GlassWire is one of the most appealing free firewalls available. With its fantastic interface, you will be able to view your current and past network activity, making it easier to detect threats to your computer. GlassWire will also alert you to any changes related to Internet activity in your PC or app. And it’ll monitor your network and alert you when unknown devices try to connect.
GlassWire Firewall has an ‘Ask to Connect’ mode to permit or deny new app connections. Perhaps its best feature is the presentation of detailed network usage statistics based on IP/host, application, and type of network traffic. And you can create custom profiles, for example, when you’re connected to your home WiFi or when you’re at work.
And if you find yourself overwhelmed by the amount of information available, you can clear the logs in a matter of seconds to bring them back to a more manageable state.
4. Comodo Firewall
Comodo Firewall offers a healthy slew of features. It’ll check that all outgoing and incoming traffic is legitimate, hide your computer’s ports from hackers, and block malicious software that may transmit your data. If any suspicious activity occurs, it will alert you immediately.
Also, it includes a secure browser, a ‘virtual kiosk,’ and a Host Intrusion Protection System (HIPS). HIPS detect suspicious behavior by a program and ask whether to allow it, block it, or treat the program as an installer.
Also, Comodo adds more secure versions of Chrome and Firefox, called Dragon and IceDragon, respectively. Comodo browsers provide security, privacy, and performance enhancements not available in regular browsers.
Comodo’s Virtual Kiosk is a virtualized sandbox, an isolated environment for anonymous applications. Apps running in the kiosk won’t affect your actual computer, which makes it ideal for testing new, untrusted apps.
5. Windows Defender
If you’re a PC running a version of Windows more recent than XP, you already have a free firewall installed, and unless you have changed any settings, it’s already active and running.
Known as Windows Defender since Windows 10, Firewall is part of a suite of security tools included by default with Windows installations. Microsoft recommends that you keep Defender turned on, even if you use another firewall.
Search for ‘Security’ in Windows and choose the Security app to manage its settings. When it opens, turn on Windows Defender Firewall. Turning off again involves taping the same button. Also, you can configure the firewall to allow a specific app through the firewall. From the same place as you toggle it on/off, you can select ‘Allow an app through firewall’ and select the app concerned.
