6 Best WordPress Firewall Plugins in 2019

Moeez — December 6, 2018 6 Minutes Read

It is 2018 and our websites and servers are more vulnerable to hacking, brute force as well as distributed denial of service (DDoS) attacks than they have ever been. Fortunately, WordPress has responded to that dilemma by arming its users with the most secure and user-friendly firewall or security plugins out there.

However, looking for one isn’t going to be a breeze as there are so many of them sitting around in the WordPress plugin directory. That’s where I swoon right in and pull out some of the best WordPress firewall plugins that are not only high in quality, but also in demand.

Before we begin, you need to know that there are two types of firewall plugins available for WordPress; a) DNS Level Website Firewall; b) Application Level Firewall.

I sincerely request the audience to utilize the DNS Level Website Firewall as it is very good at recognizing genuine website traffic against bad requests. This is done by tracking thousands of websites, comparing trends, searching for botnets, bad IPs, and blocking on pages users don’t want to see.

If that’s not good enough for you then perhaps you should also know that DNS level firewall plugins shrinks the loading time of your WordPress site, typically ensuring that your website does not go down.

So without further ado, here are the most optimal WordPress firewall plugins you should be getting your hands on:

All In One WP Security & Firewall

All In One WP Security & Firewall

Hotlinking and blocks fake Google Bots from crawling to your site. All in One WP Security & Firewall is one of the best WordPress security plugin that has earned the love and trust of every WordPress user because of its simple user interface and the fact that it is easy to use, robust, stable and highly supported. It has a host of features including:

Password Strength: This helps users create even stronger passwords that make it hard for hackers and other third-parties to decipher.

Login Lockdown: You can protect yourself against users with certain IP addresses and ranges based on the configuration settings that you choose. It is ideal for protection against brute force attacks.

Stop User Enumeration: It is so that users or bots cannot discover user info via author permalink.

Monitor Suspicious Activity: You have the ability to monitor failed login attempts, block out users at will or even simply see which users are logged in to your website.

Firewall: All malicious scripts will be blocked out before they can affect your WordPress site’s code. It also prohibits image


Sucuri is another highly revered name that needs no introduction when it comes to the best WordPress security plugins. One of its main winning aspects is the fact that it is free to every WordPress user. It is mostly renowned for the seven following features:

Security Activity Audit Logging

This feature monitors all security-related events on your WP site. It is quite strict as any changes to the application counts as a security event.

File Integrity Monitoring

When you compare a known good with the current state of your site and find that there’s a difference, you will know that there is a problem. The known good will be created upon the completion of the plugin’s installation.

Remote Malware Scanning

This feature does as the names suggest, which is to monitor and scan for any malware. It is also powered by free security scanner – SiteCheck, which makes it all the more convenient.

Blacklist Monitoring

Being blacklisted can be a bummer and that’s why this feature makes use of several security blacklist engines such as Sucuri Labs, Google Safe Browsing, Phish Tank, AVG and Norton among others. Upon scanning, you will be notified if you have been wrongly flagged and with the Website AntiVirus product, you can get off their list.

Effective Security Hardening

Security hardening can be a tiring and massive feat. But Sucuri does all that in haste without and only adds those hardening configurations that best facilitate your site.

Post-Hack Security Actions

Regardless of how good your security may be, you are bound to get hacked eventually. It is for this reason that you should capitalize on the post-hack security actions that Sucuri comes with.

Security Notifications

What good is having any of these features if you aren’t notified of them? And that is where the plugin’s inbuilt security notifications come into play

iThemes Security

iThemes Security

When I talked about sharing the best WordPress firewall plugins with you, I really meant it and iThemes Security is one of them. What was once known as Better WP Security is now a treasured name that stands on top of several other firewall plugins there are on WordPress.

The plugin specifically deals with a number of main site vulnerabilities such as brute force attacks. iThemes does plenty from locking down your WP site to fixing common holes, stopping automated attacks and buffing up your password user credentials. Here’s what you can expect from iThemes:

  • Wholly scans your site to look for any vulnerabilities and fixes them within seconds.
  • It prevents brute force attacks by banning users with too many failed login attempts.
  • Bans toxic users, bots and other hosts
  • Uses strong passwords.
  • Tightens server security.
  • Forces SSL on admin, as well as any post or page.


Next on my list is a name that you had best get acquainted with as soon as possible if you haven’t already. Cloudfare speeds up and protects thousands of sites, SaaS services, APIs as well as other things that are connected to the internet. It is largely known for its free CDN service which includes basic DDoS protection.

It is also a DNS level firewall that handles the load of your site, thereby improving its performance and reduces the downtime when high traffic is around. Apart from CDN services Cloudfare also includes caching and a wide network of servers.

Cloudfare is arguably the best WordPress security plugins. It includes a Pro plan and a Business plan. The Pro plan only consists of protection against DDoS layer 3 attacks whereas the Business version defends you against DDoS layer 5 and 7 attacks.

Perhaps the only downsides to Cloudfare is that it does not offer any application level malware protection, security scanning, security notifications, blacklist removal, and alerts. It also doesn’t seem to be able to monitor a WordPress site, a file change or other common WordPress security threats.



Being part of the Automattic family, Jetpack is quite the familiar plugin in the WordPress community. It is perhaps best known for its incredibly large assortment of functionalities that help it stand out from the rest.

If you wish to acquire the free version of Jetpack, then you will need to turn on the Protect module, which will protect you against brute force attacks. But the real meat of the plugin lies in the paid premium versions.

The Jetpack Premium license costs about $99 yearly. Its functions include 24/7 malware scanning, automated website restores and scheduled off-site website backups. The Jetpack Professional license comes in around $299 and offers real-time backups as well as on-demand malware scans.

Wordfence Security

Wordfence Security

Wordfence is one of my all-in-one security solutions that I have had the pleasure of saving for last. The plugin has been downloaded over 22 million times and has an average rating of 4.8 out of 5 stars. It is powered by the regularly upgraded Threat Defense Feed, Wordfence’s Web Application Firewall will guard you against any attack.

Wordfence Scan uses real-time feed and will alert you the very moment your site has been hacked. The Live Traffic view grants you a real-time view of the traffic and spot any hack attempts on your site. If that’s not enough, then it will please you to know that Wordfence is absolutely free and open-source.

It also offers users a Premium API key that provides you premium support, scheduled scans, country blocking, password auditing, two-factor authentication, updates to the Threat Defense Feed and it can also check to see if you site’s IP address is being to Spamvertize.

Wrapping it up!

Well that about closes the book on all the well-rounded WordPress firewall plugins that you need to know about to safeguard your WordPress site and everything else with an internet connection.
