What Is a WordPress Firewall Plugin?

A WordPress firewall plugin is software that helps protect your website against external attacks and prevents hackers from exploiting vulnerabilities in the code.

The best of them will block brute-force login attempts, stop SQL injections and XSS hacks, prevent data leaks, etc.

There are two types of firewalls, namely, a software firewall and an application-level firewall.

  • A software firewall is a program that checks the incoming data from another device, computer, or network to make sure it’s safe before allowing access.
  • An application-level firewall works by filtering out traffic at the point where information enters your system. This type of security measure is more common in extensive networks.

It has features including malware scanning, brute force detection, web application shielding against vulnerabilities, and so on.

On the other hand, if you want to play it safe without compromising too much of your site speed or functionalities, then go ahead with Wordfence.

Note: If you don’t want to use a firewall servcie or plugin, then I’ll recommend using iThemes security which is the best for the overall WordPress security solution.

If you don’t want to use any of these two firewall plugins (recommended), you can go with MaxCDN or Cloudflare for website firewalls and security protection. BUT MaxCDN is better than Cloudflare.

However, you can choose any of them. In most cases, it comes down to just a matter of preference.
