  • server: cloudflare header value and static.cloudflareinsights.com resources
Report value

Every detected technology should include category, confidence, evidence, and practical risk/context so the result is useful beyond logo recognition.

False-positive boundary

What to verify before acting on Cloudflare evidence

  • Cloudflare edge headers describe the proxy layer, not the origin application or framework.
  • Some Cloudflare features (Turnstile, Workers) may not be visible on a single page scan.
Next workflow
  • Run the Cloudflare detector to confirm cf-ray and server-header evidence.
  • Check Turnstile and other bot-protection signals if forms are present.
  • Review security-header posture for the Cloudflare-served response.
