While a proxy server protects a client machine’s identity by using an intermediary, a WAF is a type of reverse-proxy, protecting the server from exposure by having clients pass through the WAF before reaching the server. A WAF operates through a set of rules often called policies.

A WAF protects web applications by analyzing each HTTP request, and traditional WAFs ensure allowed actions based on security policies. NGFWs are advanced firewalls with integrated IPS and application-layer capabilities.

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.

A web application firewall (WAF) is a security solution that protects web applications from common attacks by monitoring and filtering traffic, blocking malicious traffic entering a web application or unauthorized data leaving the app.

2024年11月22日 · A web application firewall (WAF) is a security measure designed to protect web applications from potentially harmful HTTP traffic. Learn why it’s important.

Understand how Web Application Firewalls (WAF) defend against application-layer attacks. Learn their benefits and how they secure web applications.

WAF is a specific type of firewall, distinguished by the way it filters data packets. WAF inspects the application layer of the network and can prevent many attacks that are invisible to other types of firewalls. For example, a SQL injection attack would not be detected by a regular firewall because it does not inspect payloads of application ...
