What is Cloudflare WAF?

Cloudflare Web Application Firewall (WAF) is a cloud-based security solution that protects web applications from common web exploits and vulnerabilities such as SQL injection, cross-site scripting (XSS), and other OWASP Top 10 threats. It acts as a reverse proxy, inspecting incoming HTTP/HTTPS traffic and filtering out malicious requests before they reach the origin server. It is commonly used to protect websites and APIs from attacks, prevent data breaches, and improve overall security posture.
