Test Your Website for Web Application Firewall (WAF) Detection

Run this check along with 90+ automated tests across your domain.

Why It Matters

A WAF acts as an outer perimeter defense to filter SQL injection, XSS payloads, rate-limit bots, and mitigate zero-day CVEs.

How We Check This

We evaluate response headers, block page signatures, and edge proxy fingerprints to verify active WAF defenses.

How to Fix & Implement

Copy-paste configuration blocks tailored for your web server or edge proxy.

Frequently Asked Questions

Does using a WAF replace secure coding practices?

No, a WAF is a defense-in-depth shield; application code must still sanitize inputs and enforce access control.
