Step-by-Step Guide to Setting Up-Implementing Cloudflare AI

We have discussed how cloudflare is evolving with AI technologies to fight the recent threats on to websites. So as our continued effort we are trying to provide you with simple basic guideline to improve the website security and this is the settings list that we personally use on our website.

Setting up Cloudflare’s Web Application Firewall needs careful attention to configuration details and security settings. You need a structured approach to protect your applications properly.

Original Setup Steps

Users must first set up their Cloudflare account and configure the simple settings to start the WAF implementation. The setup begins when you create an AI Gateway as the foundation for WAF deployment. Here’s how to set up the gateway:

Access the Cloudflare dashboard
Navigate to AI > AI Gateway
Create a new gateway with a unique name (limited to 64 characters)
Select Workers AI as the provider

The system works with both authenticated and unauthenticated gateway setups. Authenticated gateways need valid authorization tokens but give better security. They stop unauthorized access and protect against bad requests that could affect log storage.

Rule Configuration Process

The next step after gateway setup is WAF rule configuration. The system starts with Cloudflare’s Free Managed Ruleset as your baseline protection. You can add custom rules in several ways to boost security:

The WAF Attack Score system lets you create rules based on specific thresholds. Enterprise customers can block requests with scores below 20. Business plan users can make rules using the WAF Attack Score Class field.

The rule configuration supports:

Advanced Rate Limiting to control request volumes
Sensitive Data Detection to prevent data leaks
Custom fingerprint creation for specific threat patterns

Here are few examples of rules that you can use right out from here:

>If you are on Enterprise Plan with Cloudflare :

{
  "action": "block",
  "expression": "(cf.waf.attack_score < 20)",
  "description": "Block requests with WAF Attack Score below 20",
  "enabled": true
}

The Business plan with Cloudflare it does provide you with more options to use like:

{
  "action": "block",
  "expression": "(cf.waf.attack_score_class in {‘very_bad’, ‘bad’})",
  "description": "Block requests classified as 'very_bad' or 'bad' by WAF Attack Score",
  "enabled": true
}

Similarily for paid plans you can get options like:

{
"action": "challenge",
"expression": "(cf.waf.attack_score < 30)",
"rate_limit": {
"threshold": 50,
"period": 60,
"mitigation": "challenge"
},
"description": "Rate limit IPs with low WAF Attack Scores",
"enabled": true
}

Also you can find the sensitive data attacks rule like:

{
  "action": "block",
  "expression": "(cf.waf.attack_score < 40 and cf.waf.sensitive_data_detected)",
  "description": "Block requests containing sensitive data with low WAF Attack Scores",
  "enabled": true
}

If you will want to block any custom finger print then you can try with the rule:

{
"action": "block",
"expression": "(cf.waf.attack_score < 25 and cf.waf.fingerprint in {‘bad_bot_123’})",
"description": "Block requests from known bad bot fingerprint with low WAF Attack Score",
"enabled": true
}

These are just sample rules that you can refer to but for more specific rules we can always be of your assistance with our managed plans.

Testing and Validation

Security teams should monitor and validate the security measures they put in place. They can check how well the WAF works through different channels:

Security Analytics Dashboard: Shows all traffic patterns, including requests the WAF didn’t block. This helps teams understand their security status and find areas where rules need adjustment.

Security Events Interface: Gives details about requests that Cloudflare security products blocked. Teams can use this interface to:

Check blocked requests and rule matches
See how well the WAF performs
Change settings based on what they observe

Enterprise customers get extra features through Cloudflare Logs to analyze HTTP requests and security events more deeply. The system looks for prompts in HTTP requests automatically and lets customers create rules for specific locations in JSON body requests.

Teams should watch how the WAF handles different threats during validation. The system tags each analyzed prompt, which lets security teams create specific rules for different threat types. Customers can then check Sensitive Data Detection matches in WAF Security Events to make sure their data protection works correctly.

Real-world Security Impact

Cloudflare’s AI-powered firewall shows remarkable security improvements in organizations of all sizes. The system proves its worth by protecting digital assets and keeping operations running smoothly.

Case Study: E-commerce Protection

Alpargatas, a global consumer brands group, runs more than 40 e-commerce platforms worldwide. The company uses Cloudflare’s WAF to secure their digital infrastructure. Note that the company needed to protect their well-known brands, Havaianas and Rothys, from targeted cyber attacks.

The system delivered outstanding results in several areas:

Bot Management stopped specialized groups from unauthorized activities and prevented fraud
Better user experience at global touchpoints stopped revenue losses
Simple, centralized interface made security operations easier

Alpargatas used Cloudflare Workers and Argo Smart Routing to control access to their worldwide e-commerce platforms. The system managed traffic precisely and kept applications running at peak performance without affecting users.

Enterprise Implementation Results

The WAF’s deployment across enterprises shows impressive numbers. The system handles 55 million HTTP requests every second. This processing power is vital to spot and stop threats across the network.

Results go beyond just performance metrics. The WAF Attack Score solution stands out in protecting against new threats. Processing time dropped by 81.90%, from 1519 to 275 microseconds. This improvement saves about 32 years of processing time each day.

Security teams found several benefits when using the WAF:

Quick threat detection through automated scanning of user-submitted prompts
Instant threat blocking near end users without human input
Built-in security at no extra cost for customers using LLMs on Cloudflare’s Workers AI

Organizations saw major improvements in their security. The system spots and blocks new threats before they become public knowledge. To name just one example, see how the WAF blocked vulnerabilities in the Ivanti Connect Secure system before public disclosure.

The system also strengthens API security by blocking various attacks. WAF works smoothly with existing security systems to provide complete protection while keeping operations efficient. This feature matters more now since APIs generate much of today’s network traffic.
