Checker - Whitelisting (Cloudflare)
Allowing the WCAG Checker to Access Your Site
If your website is protected by Cloudflare, you may need to allow our crawler or service to bypass Cloudflare's Web Application Firewall (WAF). This guide explains how to create a Cloudflare Custom Rule that skips security checks for our trusted IP address.
Security Note
This solution is secure — it won’t expose your site to new risks. It only makes a small, controlled exception that recognizes our scanner as trusted. No other traffic is affected.
Note: Replace <<ADD IP ADDRESS HERE>> with the relevant IP address provided in the below steps.
Step 1: Log in to Cloudflare
- Sign in to your Cloudflare account.
- From the dashboard, select the website (zone) you want to configure.
Step 2: Navigate to Security Rules
- In the left-hand menu, select Security.
- Click Security Rules.
- Open the Custom Rules section.
Step 3: Create a New Custom Rule
- Click Create rule.
- Name the rule 'Allow Trusted Crawler'
Step 4: Configure the Rule Expression
Configure the rule to match our IP address.
Option 1 – Rule Builder
- Field: IP Source Address
- Operator: Equals
- Value:
<<ADD IP ADDRESS HERE>>
Checker IP Addresses
- US Checker IP is:
- 15.204.47.172/32
- UK Checker IP is:
- 198.244.165.228/32
- AU Checker IP:
- 51.161.174.41/32
Option 2 – Expression
Use the following expression:
(ip.src eq <<ADD IP ADDRESS HERE>>)
Step 5: Choose the Action
For the rule action, select 'Skip'
This tells Cloudflare to bypass selected security features for requests originating from the specified IP address.
Step 6: Select the Protections to Skip
When prompted, select all WAF components to skip.
This ensures requests from our trusted IP address are not blocked or challenged by Cloudflare's security protections.
Step 7: Save and Deploy
- Review the rule configuration.
- Click Deploy (or Save and Deploy, depending on your Cloudflare version).
The rule will become active immediately.
Verification
Once the rule has been deployed:
- Confirm the rule appears in your Custom Rules list.
- Contact our support team so we can verify that our crawler can successfully access your website.
