Web Application Firewall (WAF) Detection
Identifies active edge WAF protections (Cloudflare, AWS WAF, Fastly, Akamai) that block malicious traffic and Layer 7 attacks.
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.
