Wordfence is arguably the most popular and widely used WordPress security plugin. It is designed to protect websites from malicious attacks and provide users with a secure and reliable experience.

The plugin, which is currently installed on over 3 million websites, includes an endpoint firewall, malware scanners, 2FA authentication and a suite of extra features to keep your websites safe from malicious actors.

Features of Wordfence

WordPress Firewall

Wordfence’s web application firewall identifies and blocks harmful traffic from coming into your website. The firewall is constantly being maintained and updated with the newest firewall rules, malware signatures and malicious IP addresses to keep your website safe. All malicious IP addresses are blocked in real-time using the IP blocklist, and malware scanners are also included to scan your WordPress site periodically for malicious code.

WordPress Security Scanner

Wordfence’s security scanner constantly scans your WordPress site for malware, bad URLs, backdoors, SEO spam and code injections. It also periodically checks your site for known security vulnerabilities and informs you when any is found. Your website’s content are also scanned to check for malicious links and harmful content.

Login Security

By default, Wordfence enables two-factor authentication on your WordPress site which adds an extra layer of security around the site. It also enables a CAPTCHA test on your Login Page to stop bots from gaining access to the site.

Pros and Cons of Wordfence


  • Wordfence is one of the best security plugins in the market.
  • It’s free to use (has a paid version also).
  • The software is constantly updated by a large team of maintainers to keep it up-to-date with the latest hacking trends and WordPress software.


Due to its size, Wordfence tends to have performance issues (ie., it might slow your website). For most people, that’s a small price to pay for the huge array of security features it comes with to keep your site safe at all times.

Site Security Health Monitoring

iThemes stores a log of all changes made to your site which helps in detecting malicious activity on your site. The site scanner runs at least twice a day to check for vulnerabilities in the core WordPress files (themes and plugins). With the pro version, iThemes keeps a record of user activity on your site including login/logout, user registration, theme switches and so on.

Pros and Cons of iThemes Security


  • iThemes has a free version and pro version. The free version comes with the basic security features but lacks advanced ones.
  • The pro version gives you access to the complete security toolkit to protect your WordPress site.
  • iThemes is also very easy to use and doesn’t require knowledge of cybersecurity.


  • Though the defaults will do for most users, there is so much information to take in and decisions to potentially be made. Not many users are likely to go beyond default settings.
  • Also, iThemes Security Pro is expensive. I count this as a con even though I would thoroughly recommend everyone use Pro.
