Top 10 WordPress Security Plugins

online security

With the availability of top WordPress security plugins, there’s no need for drastic measures to feel safe online.

WordPress Security Plugins to the Rescue

Whatever type of online business you pursue, you want to make sure the platform your business is on is as secure as possible. I’m not talking about the myth of a 100% impenetrable Fort Knox type security vault—the reality is, this isn’t currently a possibility in today’s world—but I am talking about taking the steps to minimize access to the sensitive data of your website from potential hackers.

WordPress is an excellent platform for your online business. As we’ve talked about before, there are many reasons for this.

One of the major benefits of WordPress is the support and flexibility offered through third-party plugins, and security plugins are no exception. Because WordPress is an open source program, when security vulnerabilities are known, there’s a wealth of plugins to help quickly patch it up—and many of these plugins are very good.

In this article, Inside eBiz will help you protect your online business from many of the hackers who are looking to take advantage of unprepared and unsuspecting sites.

The Current State of Online Security

Unfortunately, these days, online security breaches are happening all too often. According to the developers of the iThemes Security plugin, about 30,000 websites are hacked each day. For people who have sites on the WordPress platform, attacks usually occur because of plugin vulnerabilities, obsolete software, and weak passwords.

When a 15-year-old can hack into NASA’s computers and cause a 21-day shutdown, and also get into a Pentagon weapons computer system, you know that every website is potentially vulnerable. This is all the more reason to take whatever steps you can to minimize your own vulnerability.

On one hand, most big hackers won’t take the time to go after smaller businesses. They’re more interested in making their mark with government entities, large corporations, and other organizations with highly sensitive data. On the other hand, we need to watch out for unscrupulous low-level hackers who might want to do something like use our website’s server space to send out email SPAM .

Here’s some of the major organizations that have been hit by large data breaches:

Dairy Queen
Home Depot
JP Morgan

US Postal Service

Internet hacker

It’s important to be proactive in minimizing the security vulnerabilities that Internet hackers look for.

With WordPress, there are many ways to harden your website, but security plugins offer an easier solution for most people.

Although it can be very beneficial to understand the ins and outs of WordPress security to make your site as secure as possible, by using some of the plugins mentioned in this article, you can obtain many of the same features at the click of a button.

Just make sure you stay updated with whatever security plugins you choose to use. This is because once a hole or vulnerability is discovered, a good security plugin will be quickly patched up by the developer for that vulnerability. In short, always update to the most current version of the plugin!

How We Determined the Best WordPress Security PlugIns

Here’s some of the factors Inside eBiz considered to determine the best security plugins currently available for WordPress.

Range of Features

When it comes to WordPress plugins, generally speaking, the less you use on your site, the better. Instead of looking to use numerous security plugins with limited features, our aim is to mainly focus on individual security plugins that offer a breadth of security features.

And while there are a couple of plugins on this list that offer narrower security features, for the most part, we opted to mainly consider individual security plugins that offer a wide number of features.

Positive User Experiences

All of the plugins recommended in this article were personally used by Inside eBiz and evaluated. Also, Inside eBiz strongly considered the experiences, comments, and reviews of other users of the plugin.


Support is important to any product or service, but support is absolutely critical when it comes to security for your website.

In choosing the recommended security plugins for WordPress, we considered how responsive the developer was to questions and issues about the plugin, while also taking into account whether the plugin was free or not. We recognize that when it comes to support, sometimes you get what you pay for, and if a plugin is offered for free, we understand that the developer may not always have the available time to promptly respond.

That being said, Inside eBiz was more strict about support in terms of providing timely updates to security vulnerabilities.

The Best WordPress Security Plugins for Your Online Business

WordPress security

When it comes to WordPress and your online business, there’s plenty of security you can trust.


What follows is our top 10 choices for WordPress security plugins for your online business. They’re presented in alphabetical order.

All In One WP Security & Firewall

All In One WP Security & Firewall logoAll In One WP Security & Firewall is a comprehensive, user-friendly WordPress security and firewall plugin that helps you make sure yo’re taking the best security measures for your site.

After you install the plugin, it checks security vulnerabilities on your site and recommends the actions you should take to fix them. Doing so can be done at the click of a button.

The plugin determines your security level based on a point system—the more points you acquire by turning on different security features, the higher your security level.

Security rules for All in One WP Security & Firewall are categorized as “Basic”, “Intermediate”, and “Advanced”, allowing you to easily apply different security levels to your site at one time.

Here’s some of the main features offered by the plugin:

User Accounts Security

The plugin makes sure you provide proper settings for user accounts and incorporate strong passwords.

User Login Security

This includes protection against brute-force attacks, as well as the ability to force logouts and lockouts, whitelist IP addresses, monitor account activity, add captcha, and hide the WordPress admin login page.

Registration Security

If your website allows user registration for your visitors (such as with a membership site), the All In One WP Security & Firewall plugin gives you the ability to use manual approval and/or captcha to minimize SPAM.

Database Security

The features here give you the ability to change the default WP prefix and backup your WordPress database, including scheduled automatic backups.

File System Security

You can control permission settings, disable file editing within the WordPress admin, monitor system logs, and deny access to sensitive files.

You can also easily backup, restore, and modify your .htaccess and WP-config.php files to help resolve any broken functionality in your site.


The All In One WP Security & Firewall allows you to ban users from your site by specifying IP addresses/ranges or user agents.


You can add firewall protection to your site by using the .htaccess file. Because this file is processed before any other code on your site, you can stop malicious scripts before they get a chance to get started.

As stated earlier, you can instantly activate firewall settings among the existing “Basic”, “Intermediate”, and “Advanced” configurations. You can also enable more advanced settings, as well as disallow commenting vulnerabilities such as proxy comment posting and pingbacks.

Some of the other features that are included in the firewall security settings include protection against cross-site scripting, and blocking unwanted intruders from using up your resources, (such as fake Googlebots and image hotlinking).

WhoIs Lookup

If you have activity from a suspicious host or IP address, the All In One WP Security & Firewall plugin allows you to perform a WhoIs lookup to get more information about the intruder.

Security Scanner

All In One WP Security & Firewall scans the files from your site and alerts you of any changes. It will also scan your core WordPress database tables.

Comment SPAM Security

The plugin allows you to easily block IP addresses that deliver SPAM comments to your site. Comments that don’t originate from your site can be blocked altogether.

Other Features

The All In One WP Security & Firewall plugin offers other features, including the removal of vulnerable information from the HTML code of your site, the denial of access to certain files, the ability to lockdown your site (so that you can do things such as investigate attacks, perform upgrades, or maintenance work), the ability to save and apply security settings to other sites you own, and the ability to prevent the display of content via a frame or iframe.

New security vulnerabilities are discovered all the time, and the developers of the All In One WP Security & Firewall plugin state that their goal is to update it with new security features and fixes on a regular basis.

When an IP has too many failed login attempts over a specific period of time, the plugin logs and blocks that IP address across the entire connected network of users.

BruteProtect is compatible with WordPress Multisite, and only requires one API key for all sites. The plugin also works well alongside other security plugins.


BulletProof Security

BulletProof Security is performance optimized. This means the plugin is friendly to your database (no excessive MySQL queries, no excessive database data, no excessive memory and resource use of your server, etc.). The plugin can even speed up your site through use of their Speed Boost Cache Bonus Code.

BulletProof Security firewalls help protect you against hundreds of thousands of different hacking attacks by matching malicious attack patterns. It uses .htaccess security that stops malicious scripts before they even have a chance to reach the PHP code in WordPress.


Clef Two-Factor Authentication

Clef Two-Factor Authentication logoThe Clef Two-Factor Authentication plugin offers simple, strong two-factor authentication for logging into your site, without the need for passwords or one-time codes. All that’s required is a single sign in using your smartphone and the Clef Wave. The plugin can even accommodate users without smartphones through flexible password settings.

To login to your WordPress site with the plugin, you just need to open up the mobile app on your phone and sync with the Clef Wave. After you sync with the Clef Wave once, you have access to one-click sign in for all your sites.

Clef Two-Factor Authentication will also automatically log you out when you’re finished working.

The plugin uses the RSA public-key cryptosystem and stores your private key on your phone instead of a central database on Clef’s servers, keeping your login credentials secure with you.

And even if you lose your phone, you’ll still be safe because every Clef login requires two identifications—your phone and a fingerprint or PIN.

Clef protects against all password-based attacks by disabling passwords for WordPress dashboard access, API access, and automatic password resets via email.

Clef is compatible with WordPress Multisite, works well with most mainstream plugins, and offers free email and chat support.

Security Ninja logoThe Security Ninja link presented here is to the commercial version from CodeCanyon, not to the free Security Ninja Lite plugin at The free version at is not very helpful; although it tells you what security holes your site has, it doesn’t tell you how to fix them.

Some Basic Website Security Practices to Keep in Mind

security wall

Good security practices can help you put a wall between your site and possible intruders.

Although the plugins in this article will go a long way towards patching up any security holes for your WordPress site, there are some basic measures to keep in mind to help you lockdown your online business.

• Keep your software up to date, especially your plugins, themes, your web browser, and WordPress itself. New software versions typically address security holes from previous versions. Also, delete any installed plugins or themes that you’re not using.

• Only acquire software from trustworthy sources that keep their software current and well coded. This includes popular plugins and themes from, as well as well-known third-party premium plugin and theme developers.

• Always backup your website (we’ll get more into the options for backing up, in future articles from Inside eBiz). For WordPress, this means backing up not just the database, but all the files in your WordPress installation as well. Look for automated backup solutions to make the job easier.

• Choose a web host that takes security precautions seriously. For example, find a host that stays current with the latest version of PHP and makes frequent backups of your site.

• Always use a strong password, and change it every couple of months. Try to use passwords that contain characters, numbers, capitals, and even phrases. Make sure that all users for your website have strong passwords as well, especially users who have administrative privileges.

Also, don’t get into the habit of using the same password for multiple sites and logins across the web. I highly recommend a password manager to make this part of your life much easier.

• If you allow people to upload files to your website through a form on your website, make sure the form has the ability to deny malicious scripts. If you’re unsure, don’t use such a form on your site.

• Keep your computer clean of any viruses, malware, and other malicious code that could compromise the security of everything on it.

• Never login to your site on an unsecured network (such as some Internet cafes) that fail to encrypt such information as passwords.

• When using FTP to upload and download files to your site, choose to use a more secure connection (SFTP).

• Never give someone the ability to access your FTP or edit your site unless you completely trust them. If you ever need to give someone temporary access (e.g., technical support), make sure to give them a one-time login that you can change when they’re finished.

Keep Your Online Business Protected

By choosing from among the plugins on this list, you can help make your WordPress website more secure against attacks. Although it’s unrealistic to expect a site to be 100% secure, it’s up to each of us to be proactive and take whatever precautions we can do minimize the risk.

This means locking down your site to limit security vulnerabilities, having the ability to detect when an attack has occurred, and knowing how to get up and running if the worst has happened.

Inside eBiz will talk more about the best ways to get back up and running in a future article, but if your site is compromised, at a minimum, you’ll want to reset your password, get your site scanned for malicious code, and contact your web host to help you get back up and running. And most definitely, taking basic precautions means having a full backup of your WordPress files and database.

So, make sure to take advantage of the security offerings that are available out there, and be vigilant with some basic, commonsense security practices. By being proactive, you can save yourself from potential headaches down the road, and make your online business safer both for you and your customers.

Until next time, have a safe and secure 4th of July!

Hey David,
Great post!

I am currently using BackWPup but have noticed it didn’t make your list?

Do you have any experience with it? If so how does it rank against WP Security & Firewall and Wordfence (which I have used previous)?


    David - September 28, 2015 Reply

    Hi Mike!

    I do have some experience with the free version of BackWPup. It’s a decent plugin due to the fact that it gives you a backup of both your WordPress database and files. However, I didn’t include it in my list because there are many WordPress plugins that offer the same option, and it doesn’t (at least when I used it) offer an easy way to restore the backup that’s created.

    Also, the plugins I’ve included on my list generally offer a larger number of security options for your site (along with backup), including the plugins you mentioned, such as Wordfence Security, All In One WP Security & Firewall, and iThemes Security. Long answer made shorter: I was looking for options that offered more unique security features, or offered the convenience of having multiple security features within one plugin.

    Hope that helps Mike! Thanks so much for your comment!

I want to add one more good security plugin which is User Activity Log Pro Plugin. It is very helpful for monitoring and tracking of all the activities occurs on the admin side.
