BENEFITS OF CLOUDFLARE WAF
Global threat intelligence
The Cloudflare global network processes 106 million HTTP requests per second at peak, providing unparalleled protection against the latest attacks, including zero-day exploits.
Machine learning-based detection
The Cloudflare WAF uses machine learning to automatically block emerging threats in real time.
Fast deployment and easy management
Customers can set up the WAF with just a few clicks, and our WAF integrates with the rest of our application security for full coverage. No training or professional services needed.
Managed and custom rulesets
On top of OWASP rules, Cloudflare managed rules offer fast zero-day protection, and custom rulesets enable organizations to tailor their WAF to implement organization-specific policies.
HOW IT WORKS
The Cloudflare WAF runs on the Cloudflare global network and sits in front of web applications to stop a wide range of real-time attacks using powerful rulesets, advanced rate limiting, exposed credential checks, uploaded content scanning, and other security measures.
The WAF integrates with our analyst-recognized, industry-leading application security portfolio for comprehensive protection.
