9 Best WordPress Firewall Plugins In 2021Are you searching for the best WordPress firewall plugin? If you care about the security of your site, then this should be a priority.

Managing a WordPress site comes with challenges, and one very common challenge is securing your site from hackers and malware.

Although the platform is secure by itself, it is not impenetrable (no system is).

Thus, you need to add an extra layer of security to your website. Fortunately, WordPress has many firewall plugins that do just that. This means your real issue is selecting the right WordPress firewall plugin and setting it up correctly.

In this guide, we will make this decision easy by comparing the 9 best WordPress firewall plugins. We will give you the low-down on the features each plugin provides to help you choose the right plugin for your site.



Why Use a Firewall Plugin?

Simply put, they secure your WordPress website by shielding it against attacks from hackers and malware. Some firewall plugins also scan your website for security issues. Then it makes it possible to fix any issue it detects on your sites’ files such as plugin and theme files.

Brute force attack protection is one of the core functions of firewall systems. They provide this protection by reducing the number of attempts on your WordPress login page. This will save your server resources and prevent server overload (which can take down your site).

In addition, some firewall plugins can improve the loading speed of your website. If the plugin you use handles incoming requests, your server only receives genuine traffic.

This relieves your server from handling invalid traffic requests from bots. Therefore, this translates to an increase in your sites’ loading speed.

How Firewall Plugins Work

A firewall plugin adds an extra layer of security to your WordPress site. They protect against brute-force and DDOS (Distributed Denial of Service) attacks.

Brute force attacks occur when a user makes several attempts to access the admin dashboard of a website. The hacking attempts are usually automated using scripts so that it runs infinitely. This may slow down your website or even break the website completely.

Firewall plugins for WordPress provide two levels of protection. It is either DNS-level protection or Application-level protection.

DNS Level Protection

In this level of protection, the firewall plugin handles all incoming traffic. It will filter out wrong traffic and only send genuine users to your server.

Application Level Protection

With this method, all incoming traffic will go through your WordPress hosting server. Your server then takes care of filtering bad requests before showing the web page to the users.

Features to Consider When Choosing a Firewall Plugin

Firstly, you should consider the level of protection the plugin provides. Ideally, you should go for one that provides DNS level protection.

Using such plugins saves your server resources. This is because traffic will be filtered by the plugins’ servers before reaching your hosting server.

Another factor to consider is the pricing of the plugin, although some of these plugins are free to use. To unlock the entire features you may need to buy a premium license. You would want to cut costs while ensuring the plugin of choice offers the features you need on your site.
