Some of the best WordPress security plugins

After installing WordPress on any new server, it’s crucial to install at least one of the WordPress security plugins, that I’m gonna mention in this post. These security plugins scan your site regularly for malware, keep the hackers out by masking unwanted info about your server, blocks malicious IP addresses from accessing your server, and keeps the bad boys out.

The fact is that there are a plethora of WordPress security plugins in the WordPress repo. It’s just not so easy to install a security plugin that perfectly safeguards your WordPress site without causing overhead on the server.

#1. iThemes Security

iThemes Security

This is the best WordPress security plugin. I was previously using WordFence for my security needs. But the downside of WordFence is that is that the plugin is using way too resources on my server. It was causing CPU spikes on both my shared and VPS hosting servers, shutting down the database access.

Later when I was searching a good alternative to WordFence I came across iThemes Security plugin. It’s both resource friendly and offers some great features to protect you from the hackers.

After installing iThemes Security, you just need to enable all the recommended features it suggests. The plugin protects your site in 30+ different ways like fixing common WordPress vulnerabilities, stop automated attacks, strengthening credentials, Brute force protection, and others. All you need is to just activate the plugin, and you are good to go. It also offers you a free API key for you to activate the network brute-force attack prevention. It prevents your server from being hacked by the IP addresses that are known to be malicious and flagged by iThemes Security plugin on other WordPress installations.

This is the WordPress plugin I recommend you to use if you are running on shared server or if you are running on limited resources which are in most of the cases.

#2. WordFence Security


It is the most popular WordPress security plugin with over 1 million installations.

The system is constantly updated with Threat Defense Feed and web application firewall ensures that your site won’t get hacked. The major feature of this plugin is the live traffic monitoring, in which you can monitor the activities of the users visiting your site and can detect any malicious activities. This feature is resource-hungry, and you may need to deactivate this feature if you are using a shared server.

The plugin is efficient at blocking out fake Googlebots and spambots that are scanning your site for vulnerabilities and automate the attack. Your server will be blocked from the list of malicious IP networks that are identified with the help of other sites running with WordFence. This by installing WordFence, you not only protect your site but also help other sites from being attacked.

It is the most updated WordPress plugin, and this plugin was the reason why WordPress was resistant to the Heartbleed attack that affected some servers years ago.

It also ensures that the integrity of the core WordPress files and plugin files are maintained. If any unauthorized changes are made to the files that may harm the integrity of the system, the plugin notifies you instantly. It also scans for any malware in your file system and removes them by notifying you.

#3. Security Ninja

Security Ninja

This is one of the new WordPress security plugins, that’s great at securing your WordPress site.

This plugin performs 40+ security checks on your WordPress site with just one-click.

These security checks include plugin or theme vulnerabilities, brute-force attack prevention and testing password strength, version hiding. The database, PHP, and apache configuration tests are made regularly to ensure that no un-authenticated changes are made to the configuration files.

This plugin is also available as a pro version. This pro version includes modules such as core scanner, malware scanner, scheduled scanner and event logger module.

This is one of the lightweight security plugins I’ve used. I tried it on shared hosting environment also, and the plugin performs tests and scans without any lagging. It’s not that resource intensive like that of WordFence and others with real-time monitoring.

The plugin is actively being developed and the new features are being implemented after each update.

I found the interface of the plugin very easy to use than other plugins. The plugin UX is very refined and clean.

Another thing to note that is the plugin won’t make any changes to your site. It just warns you or suggests you of any security vulnerabilities and you need to fix it.

#4. BulletProof Security

BulletProof Security

This is one of the best feature-rich WordPress security plugins I’ve come across. As like that of others, this is available in both free and pro versions. The protection includes firewall security, login security, database security and backup. It implements the website firewall in the .htaccess file and imposes strict monitoring mechanisms for preventing brute-force attacks. The idle session logout and auth cookie expiration are very effective to logout a user automatically who gained access to your WordPress account without using a password by using vulnerabilities or somehow.

It also checks for any hidden plugin files, or code that does not meet the WordPress coding standards. This helps very well in detecting any nulled scripts are detrimental for your site’s security.

The pro version of the plugin includes advanced features like intrusion detection, real-time file change detection, plugin firewall, HTTP error log, database error log, etc. There are dozens of other advanced features in the pro version of the plugin.

Some of the features like real-time monitoring will cause an overload of limited CPU. These features are only suitable if you are running on dedicated servers. However, if you plan to use the plugin on a shared hosting environment, you can selectively disable the real-time monitoring features.

Security plugins on a WordPress website seems a great idea considering the number of attacks users face every year. My favorite is Wordfence though I have used Sucuri as well, but Wordfence works just fine for me.

I don’t know if you agree with me on this but I think security plugins alone is not the answer to securing your website. Users should take some precautionary measure as well apart from installing plugin. I have written a guide on WordPress security vulnerabilities ( https://www.wpblog.com/scan-wordpress-site-patch-security-vulnerabilities/ ) to provide security tips for people who rely too much on plugins.
