Being the most popular CMS in the world, WordPress is frequently the target of hacking attempts looking to breach security measures and gain unauthorized access to the site’s users and resources, causing massive financial and reputational damage. That’s why WordPress security plugins are an essential part of the ecosystem. 

Let’s explore what security plugins are, their benefits, and five of the best ones you can install to protect your site.

What are security plugins, and what are their benefits?

WordPress security plugins are software add-ons designed to enhance your website’s security and protect it from brute force attacks, SQL injections, CSRF attacks, SEO spam, and other common cybersecurity threats. These plugins add extra layers of protection, monitoring, and prevention mechanisms to safeguard websites from online threats. 

Some of the benefits of using security plugins include the following:

  • Malware protection. Security plugins often feature malware scanners that detect and remove malicious code or files from your website.
  • Firewalls. Many security plugins feature firewalls that monitor incoming and outgoing traffic. Firewalls detect and block suspicious activity.
  • Brute force attack prevention. Security plugins have measures to prevent brute-force attempts against your login page, such as limiting login attempts, implementing CAPTCHA challenges, or blocking IP addresses.
  • Two-factor authentication (2FA). 2FA is requiring a second authentication factor in addition to a password. It can be a text message, a temporary code, or something else. 2FA is one of the most effective measures to prevent unauthorized access.
  • Database security. Many security plugins offer protection against SQL injections and other attacks aimed at databases.
  • File integrity monitoring. Tracking changes to your website’s files and alerting you about suspicious modifications helps you stay aware of potential malware injections.
  • Performance improvements. Some security plugins include performance optimization features that improve website speed.

Before moving forward, remember that despite security plugins’ many benefits, they can’t solve every security vulnerability or threat. Updating your other plugins, themes, the PHP version, and core WordPress files is also essential.

Ultimately, WordPress security is an ongoing effort with constantly evolving threats and solutions. Hence, you must stay aware of both to keep your website safe. To dive deeper into basic security, read our article about security best practices.

Best 5 WordPress security plugins

There are dozens of worthwhile security plugins in the WordPress ecosystem, so it can be overwhelming to decide which to use. Let’s break down five of the most popular and highly rated ones to understand better what you should expect from a security plugin.

Sucuri Security: Best free alternative

Sucuri is a world-class cybersecurity organization that offers solutions to all CMSs but specializes in WordPress. Their free plugin, Sucuri Security, focuses on security auditing, malware detection, and security hardening.

Sucuri offers multiple security features, including a web application firewall to filter out suspicious traffic, email alerts upon detection of security threats, file and WordPress core integrity checks, a malware scanner, and others.

Sucuri’s free features not only protect your site, they may also improve performance. But if you really want to take advantage of the organization’s capabilities and harden your site even more, you may want to explore their premium plans for more advanced features.

Overall, Sucuri Security has a user-friendly interface, and its free features provide comprehensive cybersecurity for most websites. 


The Sucuri Security plugin for WordPress is free. Still, Sucuri’s website offers multiple paid plans for all CMSs, not just WordPress. They provide the following four premium plans:

  • Basic Platform. $199.99 per year. Aimed at bloggers and small websites.
  • Pro Platform. $299.99 per year. Aimed at small and medium-sized businesses.
  • Business Platform. $499.99 per year. Aimed at businesses with advanced security needs that require frequent scanning.
  • Multi-site & Custom Plans. This plan doesn’t have a set price and requires that you communicate with Sucuri directly. It’s aimed at organizations with the most complex security needs.

Free Sucuri features

  • Malware scanning.
  • Web application firewall (WAP).
  • Blocklist monitoring to ensure your site hasn’t been flagged as malicious.

Sucuri Security cons

  • Sucuri Security is an offsite solution that can only access your site’s public-facing pages. It can’t access the files on your backend.
  • The first three premium plans only cover one site domain.

Wordfence: A comprehensive freemium security plugin

With over 4 million active installations, Wordfence is one of the most popular WordPress security plugins. It offers features like a firewall, scanning for posts, comments, files, themes, and plugins, improvements to login security like 2FA and reCAPTCHA challenges, a traffic dashboard with live logins and hacking attempts, a tool for determining who owns a malicious IP address or domain, and much more.

This plugin performs regular scans, but you can also manually perform one. It’s also important to note that Wordfence’s firewall runs on your server rather than the DNS level, making it slightly less effective.

Despite this, the free version truly offers everything most website owners would need, and the premium plans provide advanced functions and support.


Wordfence’s free version is comprehensive, but they offer three premium plans with advanced features.

  • Wordfence Premium. $119 per year.
  • Wordfence Care. $490 per year.
  • Wordfence Response. $950 per year.

  • Security audits and cleanups.
  • Post-incident reports, follow-ups, and recommendations.

Wordfence cons

  • The free version has a 30-day delay for applying new firewall rules. Your website may be vulnerable to new hacking methods during that period.

Jetpack is another of the most popular security plugins, with over 5 million active installations. It’s developed and maintained by Automattic, the company behind WordPress.com, making it a trusted and reliable alternative.

Jetpack is a security, backup, and performance plugin. The free security options provide a basic solution through malware scanning, brute force login protection, activity logging, and real-time backups, in addition to other performance features. The premium plans expand these functions with various security add-ons, including a web application firewall and increased spam protection for comments and forms.

Given the relative need to use premium features for complete protection, Jetpack may be a better option if you’re already considering premium subscriptions that also net you advanced backup and performance features.


Jetpack has multiple add-ons for security, backups, performance, and content management. It also provides two yearly subscription bundles.

  • Security. $9.95 per month (billed annually) for the first year, then $19.95 per month. This bundle contains all security add-ons: VaultPress, Akismet Anti-Spam, and an advanced scanner.
