Best WordPress Security Plugins To Protect Your Websites in 2021

You probably know already that WordPress is the largest content management system (CMS) which powers over 30% of all websites on the Internet. The figure just keeps growing since users launch 50 thousand WordPress-based websites each day.

But do you know that the popularity of this CMS brings a proportional share of security issues? According to the report, 90 thousand attacks on WordPress sites occur every minute. It’s a huge threat that could jeopardize years of hard work and content creation within seconds, so you need to think about the best protection model.

A study reveals that over 70% of the most popular WordPress installations are vulnerable to vulnerabilities which can be detected using free automated tools, plugins in particular. However, when you enter “security” in the WordPress plugin search box, it displays more than 300 results.

In such circumstances, it becomes extremely difficult to check all options and find the one that suits your website the most. That’s why we decided to cut the long story short and present you the best WordPress security plugins. Let’s see our top 10 picks!
