Before we dive into some WordPress security plugins, let’s start with an example. Say you buy a new house. This exciting new investment requires a hefty down-payment you’re probably not used to spending. And, of course, you’re hit with inspection fees prior to buying. Then comes the mortgage and insurance payments, all of which come straight out of your pocket.

They say purchasing real estate is one of the best investments you can make, but that investment is a costly one. For such a high-value investment (and something that could make you big bucks in the future,) would you not want to protect it to the best of your ability?

That’s why you buy insurance and consider setting up an alarm system or some security cameras. Many experts suggest at least placing a security system sign on your door, to scare away those who don’t want to risk it. All of this security is meant to protect the initial investment, along with the potential for that investment in the future.

And you should think the same way when it comes to your WordPress website.

Starting a blog, ecommerce website, or small business site requires an upfront investment for items for services and products like hosting, themes, plugins, and website development. That doesn’t include any help you must hire, such as customer service reps or salespeople.

This initial investment alone is enough to secure your website from the start. But more importantly, you’re making sure that you don’t forget to protect the potential money you’re going to make in the future.

By default, WordPress core has some security measures in place, but it’s nothing compared to what a reputable security plugin does for you. For example, the top WordPress security plugins deliver the following:

Your First Priority Should Be Secure Hosting

The security of your site is only as good as the backend and foundation it’s running on. That’s why it’s important, before looking into security plugins, that you choose a WordPress hosting platform that has security measures already in place, such as Kinsta. Many of these safeguards are done at the server-level, and can be far more effective, without harming performance on your site. Not to mention you don’t have to spend time fiddling with a bunch of security settings in plugins which in you might not even understand their functionality or purpose.

Secure WordPress Hosting

Here are a few security features that Kinsta offers on all WordPress managed hosting plans.

It’s important to note that a lot of security plugins cause performance issues due to their always-on and scanning functionalities. That’s why Kinsta bans some (not all) security plugins. Kinsta also utilizes load balancers with Google Cloud Platform which means in some cases IP blocking features of some security plugins won’t work as intended.

If you’re a Kinsta client we highly recommend utilizing a solution such as Cloudflare or Sucuri, along with Kinsta, if you need extra protection or help to decrease bot and or proxy traffic. Check out our blog post on how Sucuri helped to easily mitigate a DDoS attack. For Cloudflare users, these are our recommended firewall settings.

However, not every host is going to have as tight of security in place as Kinsta, and that’s where WordPress security plugins can be very beneficial.

Best WordPress Security Plugins in 2021

If you’re in a hurry, feel free to click on the following links to test out the security plugins and make your own decisions. If you’d like to see our in-depth analysis, keep reading!

Most worthwhile security plugins have a price tag, but there are a few that come with limited functionality for free.

We’ll talk about the pricing, but it’s more important to understand what each plugin is going to do for you. Ultimately, it’s all about figuring out the best way to keep the bad guys away from your investment–and sometimes that means spending a little money.

1. Sucuri Security – Auditing, Malware Scanner and Security Hardening

The Sucuri Security plugin offers both free and paid versions, yet the majority of websites should be fine with the free plugin.  For instance, the website firewall requires you to pay for a Sucuri plan, but not every webmaster feels like they need that type of security.

Sucuri Security WordPress plugin

As for the free features, the plugin comes with security activity auditing for seeing how well the plugin is protecting your website. It has file integrity monitoring, blacklist monitoring, security notifications, and security hardening. The premium plans open up customer service channels and more frequent scans. For instance, you might want a scan to be completed every 12 hours. For that, you’d pay about $17 per month.

2. iThemes Security

The iThemes Security plugin (previously known as Better WP Security) is one of the more impressive ways to protect your website, with over 30 offerings to prevent things like hacks and unwanted intruders. It has a strong focus on recognizing plugin vulnerabilities, obsolete software, and weak passwords.

iThemes Security WordPress plugin
iThemes Security WordPress plugin

Although some basic security features are included with the free version, we highly recommend upgrading to iThemes Security Pro for the low price of $80 per year. This provides ticketed support, one year of plugin updates, and support for two websites. If you’d like to protect more sites, you have the option to upgrade to a more expensive plan.

As for the primary features in the pro version, iThemes Security Pro provides strong password enforcement, the locking out of bad users, database backups, and two-factor authentication. These are only a few of the ways to protect your site with this WordPress security plugin. You can activate 30 total security measures, making iThemes Security Pro a great value.

3. Wordfence Security

Wordfence Security is one of the most popular WordPress security plugins, and for good reason. This gem pairs simplicity with powerful protection tools, such as the robust login security features and the security incident recovery tools. One of the main advantages of Wordfence is the fact that you can gain insight into overall traffic trends and hack attempts.

Wordfence Security WordPress plugin

Wordfence has one of the more impressive free solutions, with everything from firewall blocks to protection from brute force attacks. However, a premium version is sold starting at around $99 per year for one site. The plugin creators also make it cheaper for developers, providing steep discounts when you signup for multiple site keys. For instance, if you buy 15+ licenses, you’ll get 25% off or $74.25 per license. Overall, it pays to consider Wordfence if you’re developing multiple websites and want to protect them all.

4. WP fail2ban

WP fail2ban delivers one feature, but it’s a rather important one: protection from brute force attacks. The plugin takes a different approach which many see as more effective than what you get from some of the security suite plugins listed above. WP fail2ban documents all login attempts, regardless of their nature or successfulness, to the syslog using LOG_AUTH. You have the option to implement a soft or hard ban, which is different from the more traditional approach of only choosing one.

WP fail2ban security plugin

There’s not much to know in terms of configuration for the WP fail2ban plugin. In fact, all you have to do is install it and let it do its magic. In addition, the brute force security plugin is completely free so you don’t have to worry about spending any money. This plugin is truly a standout, since the users consistently report that it works flawlessly.

As one of the most feature-packed free security plugins, All In One WP Security & Firewall provides an easy interface and decent customer support without any premium plans. This is a highly visual security plugin with graphs and meters to explain to the beginners metrics like security strength and what needs to be done to make your site stronger.

6. Jetpack

Most people who use WordPress are familiar with Jetpack, and it’s mainly because the plugin has so many features, but it’s also because the plugin is made by the people from Jetpack is filled with modules to strengthen your social media, site speed, and spam protection. There are so many features in Jetpack that it’s definitely worth exploring.

Jetpack WordPress security plugin
Jetpack WordPress security plugin

Some security tools are included with Jetpack as well, making it an appealing plugin for those who want to save money and rely on a reputable solution. For instance, the Protect module is free and it blocks suspicious activity from happening. Brute force attack protection and whitelisting is also supported by the basic security functionality from Jetpack.

That said, the paid versions of Jetpack are more powerful when it comes to security. For instance, the $99 per year plan includes malware scanning, scheduled website backups, and restoration if anything goes wrong. Furthermore, the $299 per year plan offers on-demand malware scans and real-time backups for the ultimate protection.

Features That Make Jetpack a Great Choice:

SecuPress is a newer security plugin on the market (originally released as freemium in 2016), but it’s definitely one that’s growing rapidly. It’s actually developed by Julio Potier, one of the original co-founders of WP Media, who you might recognize, as they develop WP Rocket and Imagify. There is both a free version and premium version which includes a lot of additional features.

SecuPress WordPress security plugin

If you want a security plugin that has a great UI and easy to use interface, SecuPress is definitely the plugin to go with. The free version features anti-brute force login, blocked IPs, and a firewall. It also includes protection of your security keys as well as blocks visits from bad bots (which you usually have to pay for in other security plugins).

Features That Make SecuPress a Great Choice:

BulletProof Security WordPress plugin

I’d suggest you try out the free plugin first, since it offers the following tools:

Thanks to it, the WPScan plugin is able to scan your WordPress core version, plugins, and themes for known security vulnerabilities.

Additionally, the plugin also has various other security checks, such as scanning for exposed debug log files, backed-up wp-config.php files, users with weak passwords and more. WPScan has a Free API plan that should be suitable for most WordPress websites, however, also has paid plans for users who may need more API calls.

Features That Make WPScan a Great Choice:

10. VaultPress

It’s important not to forget VaultPress, since it works similar to plugins like iThemes Security Pro and Sucuri Scanner. You need to pay in order to get any type of protection, but the plans start at only $39 per year, making it one of the more affordable premium security plugins. The website states that this plan is more for small businesses and bloggers, but you also have the option to upgrade to a more powerful plan for either $99 per year or $299 per year.

The daily and real-time backups are the bread and butter of the operation, with a beautiful calendar view for specifying when you’d like to complete your backups. You can also complete site restores with a quick click of the mouse. What’s more is that the restore files are logged in the dashboard, and several of them are stored so that you can choose which one you want.

11. Google Authenticator – Two Factor Authentication

The majority of plugins that have individual security features don’t make much sense to install. The reason for this is because you can typically go with a plugin like iThemes Security Pro and get that one feature along with dozens of other ones. However, two-factor authentication is a different story, since it seems like most security suites don’t include it. Therefore, it might make sense to harden your login security with a plugin like this.

Google Authenticator WordPress plugin
Google Authenticator WordPress plugin

The Google Authenticator plugin adds a second layer of security to your login module, which is rather important since the majority of hacking attempts happen with the login. In addition to your regular password, this plugin either sends a push notification to your phone or some other form of authentication such as using a QR code or asking a security question.

This way, your login becomes far less penetrable since the second layer is most likely something that only you know or have on your person (like your phone).

This WordPress security plugin doesn’t require any payment, and the interface is easy enough to understand. Besides choosing the type of authentication, another cool feature lets you specify which type of user role should have to go through the authentication. So, you can allow admins to get in easier, but you might ask that authors or other users go through the two-factor process.

The only problem is that the two-factor authentication makes it rather difficult to log in to your backend with a mobile device.

Features That Make Google Authenticator a Great Choice:

12. Security Ninja

Security Ninja has been around for over seven years. Starting out as one of the first security plugins sold on CodeCanyon (with four add-ons available) it moved to a freemium model in 2016. Add-ons were ditched in favor of having just two versions – free and premium. The main module (which is the only one available for free) performs over 50 security tests ranging from checking files and MySQL permissions to various PHP settings.

Security Ninja WordPress plugin

Security Ninja also does a brute force check of all user passwords to weed out accounts with weak passwords such as “12345” or “password”. This helps educates users on security. It does include an auto fixer module, but for those who want to understand what’s going on, there’s a detailed explanation of every test including code to manually fix the security issue. If you don’t like plugins messing with your site, Security Ninja offers a nice alternative to the usual “just click here to fix it” approach. Other modules in the paid version, start at $29 a year per site.

Features That Make Security Ninja a Great Choice:

Which WordPress Security Plugin is Best for You?

Now that we’ve walked through the best WordPress security plugins, take a look at our main recommendations below. This makes it easier for you to select one or two plugins without having to test every single one out. Remember, that depending on what your WordPress host already offers, security plugins may not be needed.

These suggestions hone in on certain situations where you might choose one security plugin over another.

Besides installing a plugin you can take further steps to improve the security of your sites. For example, Lockr’s offsite key management (this is a premium service) solution protects against critical site vulnerabilities and helps to secure your data. A simple integration is available for WordPress.
