Best WordPress Firewall Plugin in 2021

Are you searching for the best WordPress firewall plugin to install on your site?

A WordPress firewall plugin allows you to secure your site against brute force, DDoS attacks, traffic spams, and several other web threats.

In this article, we will explain to you the best WordPress firewall plugin.

Let’s first understand what a WordPress firewall plugin is

What is a WordPress Firewall Plugin?

A WordPress firewall plugin (also known as web application firewall or WAF), serves as a shield among your site and all incoming website traffic.

These web application firewalls (WAF) monitor your website traffic and blocks several possible security threats before they attack your WordPress website.

Apart from significantly improving your WordPress security, these web application firewalls often speed up your site and boost performance.

Below we have listed two common types of WordPress firewall plugins available:

DNS Level Website Firewall: This type of firewall plugins routes your website traffic via their cloud proxy servers. This allows you to filter out the illegitimate traffic and just send genuine traffic to your server.

Application Level Firewall: An application-level firewall plugin starts examining the traffic once it reaches the server and before most of the WordPress scripts are loaded. However, this firewall method is not as effective as a DNS level firewall in minimizing the server load.

We suggest you use a DNS level firewall as they are ideal for filtering out the bad request vs genuine website traffic.

So without further ado,, let’s have a look at some of the best WordPress firewall plugins that you can use to filter spam traffic.
