Over a third of websites (37%) are hosted on WordPress, making it the world’s most popular content management system (CMS). This includes everything from blogs to e-commerce sites that collect and process data protected under regulations like PCI DSS. While the popularity of the platform is good for WordPress, it is also good for cybercriminals.

Having a massive number of websites hosted on a single platform means that a vulnerability in the WordPress platform provides cybercriminals with access to a massive number of sites. The use of WordPress plugins and themes further expands the potential attack surface of WordPress-based sites.

Additional security measures

Along with these WordPress plugins, you should also follow a few security best practices on your site. These steps will help you in improving the security of your WordPress site:

  • Keep WordPress updated: WordPress frequently receives updates that patch newly-discovered vulnerabilities within the plugin. Due to WordPress’s widespread usage, these vulnerabilities are prime targets for cybercriminals. Always keep WordPress sites updated to the latest version to avoid being hacked.
  • Keep plugins updated: The WordPress platform is only part of the code used in a WordPress site. WordPress plugins commonly have vulnerabilities as well, and major ones — used by many sites — are also common targets for attackers. Install plugin updates as soon as they become available.
  • Only use reputable plugins: Not all WordPress plugins are created equal, and some may be actively malicious. Only use plugins from trusted sites and organizations on your WordPress site.
  • Use a hard-to-guess username: If your administrator account has the username admin, then all an attacker needs to guess is the password to gain access. Use a different username to increase the difficulty of performing a brute-force attack against your account.
  • Use a strong password: Weak and reused passwords place the security of your WordPress site at risk. Built-in limits on failed logins don’t help if an attacker guesses the right password the first time because it is weak or is shared with another account and was leaked in a data breach. Use a strong, long and random password to protect your WordPress site.


These eight best WordPress security plugins all offer different functionality in their free and/or paid options. However, all of them provide core security functionality that is essential to protecting a WordPress site against attack.

On its own, WordPress is not perfectly secure, so adding at least one free security plugin can help to increase a WordPress-based site against exploitation. Paid versions of the plugins offer additional protections and reduce the need for manual configuration, scanning and attack remediation.

Attacks against WordPress-based sites are becoming increasingly common. Taking steps to harden your WordPress site is necessary to protect it against being hacked.
