8 WordPress WAF to Prevent Security Threats

Securing a site is always challenging, and it is every site owner’s responsibility.

There are thousands of online vulnerabilities, and it’s difficult to ensure everything on site is hardened and secured manually.

A hacked website report by SUCURI indicates that over 96% of WordPress sites were infected.

One of the quickest ways to protect the WordPress site is to use WAF (Web Application Firewall).

WAF adds multiple security elements on the fly and protects from known & unknown online threats. There are two types of WAF implementation.

• Cloud-based – cloud-based security provider protects a site. This sits out of your hosting infrastructure at the network edge.
• Hosted – usually, a plugin that is installed on WordPress and requests are examined, protected, blocked after reaching requests to the web server.

I bet you’ve asked which one is better.

Well, it depends on the approach, but I prefer cloud-based. By using a cloud-based security provider, all bad traffic is blocked on their network, and you receive only legitimate requests.

Let’s see the following some of the best web application firewalls we have for WordPress.
