Secure your WordPress site and speed it up using CloudFlare’s powerful tools for blocking threats and reducing resource usage.


Keeping your WordPress site safe from hackers and running fast are top priorities for any site owner. Recent malware attacks have highlighted the need for better security. Meanwhile, optimized performance ensures a smooth experience for visitors. This guide covers two easy ways to leverage CloudFlare to both protect your site and improve speed by reducing strain on your server resources.

Solution 1: Disable XML-RPC in WordPress

XML-RPC is a feature that allows remote APIs to communicate with your WordPress site. Most sites don’t need it active. Unfortunately, XML-RPC can be exploited by attackers to compromise your site. Disabling it improves security.

To disable XML-RPC:

Step 1: In the CloudFlare dashboard, go to Security > WAF (Web Application Firewall)

In the CloudFlare dashboard, go to Security > WAF (Web Application Firewall)

Step 2: Create a rule blocking URI containing “xmlrpc

Create a rule blocking URI containing “xmlrpc”

Step 3: Deploy the rule

Blocking XML-RPC prevents unneeded traffic from reaching your server. This lightens the load and frees up strained resources.

Soluton 2: Scrutinize Login Attempts

Login pages are a prime target for brute force attacks. CloudFlare can add an extra layer of protection by scrutinizing every login attempt.

To activate:

Step 1: Create a page rule in CloudFlare for your /wp-login.php URL

Create a page rule in CloudFlare for your /wp-login.php URL

Step 2: Set the Security Level to “I’m Under Attack

Set the Security Level to “I’m Under Attack”

This subjected all login traffic to maximum scrutiny, blocking suspicious access attempts.
