Best WordPress Security Plugins to Protect Your Website

Are you using WordPress to run your business or eCommerce website? 43% chances are that you are – as WordPress now powers over 43% of the web. WordPress is undoubtedly the most popular blogging, eCommerce and web-development platform in the world right now. But is it the most secure?

WordPress' code is Open Source. So means even you can view the source code and create applications (called Plugins & Themes) to modify how it functions. This helps in creative freedom. But since the code is open source and there are chances you can leave some parts of your website open to hackers, there are higher chances your website can get hacked.

This is where WordPress security plugins come into play.

WordPress security plugins can create a firewall, tighten your website's security and block DDoS attacks so that you focus on your business and don't lose your sleep on hacks.

Best WordPress Security Plugins

If you are looking for a WordPress security plugin, you can pick one from the list below. Be sure to also apply other security measures like strong passwords, CDNs and server-based firewalls to ensure 100% website security. In addition to these, if you run an online business, be sure to apply IAM security (know what IAM is here).

Without further ado, here are the best security plugins for WordPress:

Defender and Defender Pro

I could list over 100 plugins alongside these top WordPress security plugins, including but not limited to - iThemes Security, WPScan (now a part of Jetpack Security), SecurityNinja, Astra Security and more. But these 5 are near-perfect for any type of WordPress site and thus, these made their cut to top WordPress security plugins.

As I wrote earlier, be sure to use any of these plugins with a server-side firewall (or just use Cloudflare) so that you can stay assured of the full security of your websites.
