Last updated on

Installing a security plugin is one of the ways you can do to reduce the risk of a cyber-attack. A security plugin is particularly crucial if you have no adequate knowledge of web security.

Most security plugins come with a firewall feature to prevent unauthorized users to log in to your website. They also block the IP addresses of the attackers to prevent them from making other attacking attempts.

In addition to blocking illegal login attempts and cyber-attacks in any form, some security plugins also audit the security aspect of your website. For instance, they will let you know if there are plugins or themes that need to be updated to improve security.

Here are 11 of the best WordPress plugins you can install to help to secure your website.

1. Wordfence

Wordfence is the most popular security plugin for WordPress with over 4 million active users. It is one of the security plugins that have the most comprehensive features. First, Wordfence comes with a firewall feature to provide the main security layer to your website. The feature will block all of the attack attempts made by attackers — illegal logins in particular.

Second, Wordfence comes with a malware scanner that will scan the core WordPress files, theme files, and plugin files to look for malware potentials, bad URLs, SEO spam, and other threat issues. The Live Traffic feature of Wordfence allows you to monitor the suspicious traffic on your website and instantly run WHOIS to learn the detailed info about the traffic you suspect. You can then instantly block the IP address of the suspected traffic.

To keep you updated about the security issues on your website, Wordfence also offers email notifications. You will be emailed every time Wordfence has just locked out new illegal login attempts, as well as other activities about security issues on your website. Here are the key features offered by Wordfence.

  • Firewall
  • Malware scanner
  • Email notifications
  • Password security
  • Login protection (you can enable two-factor authentication)

Wordfence itself is released as a freemium plugin. You can upgrade to the pro version in case you need to unlock more advanced features.

2. Sucuri Security

Same as Wordfence, Sucuri Security is also released as a freemium plugin so that you can use it for free to secure your WordPress-powered website. However, the features offered by the free version Sucuri plugin are very limited. For instance, the free version doesn’t offer a firewall. To be able to use the firewall feature, you need to provide the API key, which you can get by subscribing to one of the Sucuri Security plans. If you don’t need a firewall — assuming you will use the free version — then Sucuri is worth enough to try.

Sucuri Security will audit the security aspect of your website right after you install and activate the plugin. You will get notifications if it found malicious JavaScript, malicious iFrame, blackhat SEO spam, and so on. Sucuri also offers email notifications to keep you updated over the security issues on your website. Here are the features offered by the free version of Sucuri Security:

  • Malware scanner
  • File integrity monitoring

3. Limit Login Attempts Reloaded

Brute-force is one of the most common cyber attack forms. It is an attack form where someone is attempting to login into a website by submitting a combination of username and password randomly.

Limit Login Attempts Reloaded is one of the plugins that you can use to set the maximum login attempts to your website. It’s quite easy to use. If you already have a list of IP addresses you want to block, the plugin also comes with IP address block manager whereby you can add the blocklist and safelist.

Installing a security plugin is crucial if you have a WordPress-powered website. While there is no system that 100 percent secure, installing a plugin will reduce the risk of being hacked.

It’s way better to make prevention rather than recovery. When looking for a security plugin, we recommend choosing one that offers a firewall feature to block attack attempts to your website.
