6 Best WordPress Firewall Plugins (Compared)

Are you worried that hackers are trying to break into your website?

We wish we could tell you that there is no need to worry but the truth is that it’s totally possible that hackers are looking for ways to gain access to your website. In fact, over 90,000 hack attempts are made on WordPress sites every minute.

Once your website is hacked, hackers use it to execute malicious activities that will damage your website.

Your website will become slow, you will start losing traffic and then your search engine ranking will take a hit. This will inevitably affect your revenue collection. Moreover, things can snowball further and Google may blacklist your site and your hosting provider may suspend your WordPress site.

Needless to say, it’s important to secure WordPress websites and one of the best ways to do that is by using a firewall. A WordPress firewall will block malicious traffic from accessing your site, therefore, deflecting any hacking attempt.

In this article, we’ll show you the top WordPress firewall plugins that you can use to protect your website today.

What is a WordPress Firewall?

Using a firewall is one of the oldest ways to protect a system from hack attempts.

Many of you may already know that firewalls protect your computer, even your smartphone from hack attacks.

When it comes to websites, firewalls help protect a website from hackers and bots. It investigates traffic, identifies bad traffic, and blocks it from accessing your website, therefore, it prevents any incoming attacks.

By using a firewall, you can ensure that only good traffic, i.e. traffic without any malicious intent can access your website.

WordPress firewalls (as the term implies), are designed specifically for WordPress websites. They are customized with rules tailored specifically to thwart attacks that are launched at WordPress websites.

There are two types of WordPress firewalls. Those are:

  1. Plugin-based Firewall
  2. Cloud-based Firewall

1. Plugin-based Firewall

A plugin-based firewall can be easily installed on a WordPress site, just like any other plugin. As traffic requests pour in, the plugin investigates the traffic, following which the traffic is either blocked or allowed to proceed to the website.

2. Cloud-based Firewall

Cloud-based firewalls which, as the name suggests, are installed on a cloud-based data center that is external to your website. Traffic coming to your website is first sent to that remote data where they are investigated. Good traffic is sent back to your website and the bad ones are promptly blocked.

As you can imagine, installing a plugin-based firewall is easy. But setting a cloud firewall involves a few steps. You will need to configure the firewall to ensure that the incoming traffic is sent to the data center and not your website server. It’s not a complicated process and generally, the firewall offers step-by-step instructions on how to do that.

To further understand how the firewalls are different from one another, let’s use an analogy.

Imagine your website as your house which has implemented two types of protections.

It has a security guard deployed at the door and there are high walls surrounding the house to keep intruders out. The wall is the type of protection that a cloud-based firewall provides. And the security guard offers the type of protection a plugin-based firewall provides.

Besides preventing malicious traffic, WordPress firewall can be configured to meet the security needs of your WordPress website. For instance, you can configure your firewall so that a user can only spend a few minutes on the WordPress login page. In this way, you can prevent specific kinds of attacks like brute force attacks from compromising your website.

How Does a WordPress Firewall Work?

The sole focus of a WordPress firewall is to protect your website from a hack attack. Firewalls do this by taking the following steps –

→ Typically, they sit in front of your website server to review the incoming traffic.

→ Every firewall comes with a list of known malicious IP addresses. Every device connected to the internet has a unique identification code called an IP address. When someone tries to access your site, the firewall checks their IP address against its list to see if it has a malicious history.

→ If it’s a match, the traffic request is immediately blocked.

→ Besides known malicious IPs, the firewall has certain rules via which it determines new threats. When it finds a new threat, the firewall adds it to its list so that when the malicious IP launches an attack on your WordPress website again, it is promptly blocked.

In this way, the firewall protects your WordPress website.

Now let’s look at the best WordPress application firewalls that you can install on your site.
