Every device should have firewall software installed, whether it’s a computer, a tablet, or a mobile device. Your device’s firewall helps keep all your data safe while protecting your device from unauthorized traffic. Firewalls are commonly used by individual users, businesses, large corporations, and government websites.
When searching for the proper firewall for your device, you should keep a few things in mind. One of the most important aspects is that your firewall should be able to protect any device connected to the internet. Along with the vital security features, the firewall should also be easy to set up, use, and update. Other desirable features include personalization options, real-time alerts, reliable customer support, quick performance, and many other tools.
While many firewall tools come with a cost, you can easily find firewall programs that will do the trick just as well and not have to pay a penny for them! This guide will provide a comprehensive list of some of the best free firewall programs you can install on your device in 2022.
Comodo Firewall is one of the best firewall programs you can find. You can download it for free if you only care about having a firewall, but they do have a yearly plan that costs $29.99 for those who want maximum security. The installation process is relatively straightforward and only takes a couple of minutes.
The reason Comodo Firewall is one of the best options is due to its lengthy list of features. It’s compatible with all versions of Windows, from Windows XP to the latest version of Windows 10. Once you install the firewall on your device, it will immediately start checking for incoming and outgoing network traffic, filtering unauthorized traffic.
Other features include auto-sandbox technology, personalized alerts, cloud-based behavior analysis, a user-friendly interface, and automatic updates. If you experience any issues or have any questions, Comodo Firewall’s 24/7 customer service is there to help.
