Many people think the built-in firewall their Windows, Android, iOS, and other operating systems have is enough. However, that is not the case.
But do not worry. You need no extra cash for additional firewall software; there are some of the best free firewalls you can install.
However, before you get your hands on top-notch free firewall programs, it would be best to cover the basics first.
Why do you need a firewall?
A firewall is software or hardware that prevents hackers and certain types of malware from gaining remote access to a computer over the World Wide Web.
Its purpose is to verify information received from the Internet or a local network and block or allow computer access.
The firewall is not the same as an antivirus or anti-malware program.
Firewall programs protect against internet worms and hacker attacks. In contrast, anti-virus programs protect against viruses (as the name suggests), and anti-malware applications shield your device against malicious programs.
