One way this can happen is unsupported or outdated plugins and themes. Alternatively, weak password rules could pose a threat to your website.

Below is a list of essential WordPress security plugins for your websites.

Top 20 Best Security Plugins for WordPress

1. All-in-One WP Security

All In One Wordpress Security Plugin

With this plugin, the name is no exaggeration.

The All-In-One WordPress Security plugin for WordPress could be a great solution for a wide array of reasons.

Heavily focusing on brute force attacks, giving you optimum protection against the most common form of security breaches, this plugin offers you 360-degree security.

Using a security point grading system, the plugin can measure how well your site is protected.

This is based on the security features already in place.

You can then choose the level of protection you require as the plugin separates the website firewall protection into three different levels; basic, intermediate and advanced.

Furthermore, all-in-one includes protection against the WordPress database as well as core files as the plugin continually scans for any unusual changes.

Although, probably the most impressive feature of the All-In-One WordPress Security plugin, besides being a free security firewall, is that before you make any changes to the settings of the plugin, it will inform you how your overall security score will be impacted.

Not only making it highly user-friendly, but the plugin is also a great tool to learn about on-site security.

2. iThemes Security

Ithemes Security Plugin

iThemes is one of the most notable names in WordPress Security plugins and has been developing WordPress tools since 2008.

It is, therefore, no surprise that iThemes Security Pro is one of the most popular security plugins for a WordPress site.

The plugin is capable of tackling the principal vulnerabilities your website is likely to encounter. For example, the plugin offers protection against brute force attacks by blocking users who have previously attacked other websites from accessing your WordPress site.

To do this, the system report ID addresses of failed login attempts and blocks them. 

Also, two-factor authorisation is provided by iThemes Security Pro. The plugin will send a unique code to the user’s mobile device. The code alongside the password is the primary way of logging in.

Other essential features of the iThemes Security Pro plugin include file change detection. Whenever something suspicious happens to a core file on your WordPress site, you will receive an email notification.

3. Shield Security

Shield Security is a small plugin when compared with some of the more well-known plugins, but the reviews are near perfect considering this, and it is no surprise why when having a look at the plugin.

This is thanks to the settings that result in an admin lock meaning an access key is required if you want to make any changes. 

Furthermore, Shield Security will not modify any of your core files. Therefore you gain access to additional options if something goes wrong, such as locking yourself out of your site.

Similar to other WordPress security plugins, you get two-factor authentication, core file scanner, automatic IP blocking system as well as a spambot blocker.

16. Jetpack

Jetpack Wordpress Plugin

Jetpack, part of the Automatic family, can be described as a combination of unrelated functionalities.

Some of the most critical current modules include site stats, widget visibility, markdown as well as custom CSS.

A large number of modules, currently 30, may seem appealing.

However, it is worth noting whether you need every single one. This is as there have been some reports that installing Jetpack can increase the loading time by between eight to ten seconds.

Jetpack is your site’s security detail, guarding you against brute force attempts and unauthorized logins. Basic protection is always free, while premium plans add expanded backup and automated fixes.

Jetpack’s full suite of site security tools include:

20. WP Performance & Security

Firstly, the plugin can disable comments and links in comments and media files; this is perfect for preventing any spam comments from clogging up your website comment section.

You can also remove the WordPress version string; this is a great way to avoid the event of hackers to attack or exploit known vulnerabilities on your website.

However, although this plugin is still fairly basic when compared to the others, it is still a useful plugin to install – especially if you are looking to change the login page or have better control over the comments section.

To conclude, as you can see, there are many WordPress security plugins available to download.

Although a lot of them seem to do the same thing, there are a few standouts that we would recommend trialling.
