Quickly identify if a website has a Web Application Firewall (WAF) deployed, detect its type and vendor, and get reliable data for security operations.
Sends the domain to a server-side scan service. Detection uses response patterns; no detection does not prove a WAF is absent. Service configuration and connectivity may cause failure.

Overview
Understand what the tool solves, how it works, and the boundaries of its data.
Enter a domain or URL and run a check. The result reports whether a web application firewall was detected and, when available, a provider or firewall label; a manufacturer may also be shown. If no match is reported, the page displays “No WAF Detected.” A WAF inspects HTTP traffic and may block requests it judges suspicious, but its deployment can be in front of a site, on a server, or within another network layer.
Presence checks infer from observable responses and identifying signals. OWASP notes that headers, cookies, block pages, or differences in responses can reveal clues, while some deployments may be difficult to detect. Therefore, “detected” is evidence of an observed signature, and “not detected” is not proof that no firewall exists.
Use a domain such as example.com or a URL beginning with https://. Confirm the spelling and host before submitting.
Run the check and wait for the status. The result area shows detected or not detected and may include provider or manufacturer text when returned.
Keep the checked host, time, and result together. If the result matters operationally, verify it through your own configuration and monitoring records.
A named result is an identification clue from the check, not a complete configuration report. It does not establish which rules are enabled, whether traffic is reaching the firewall, how origin access is configured, or whether the application is protected against a particular vulnerability. A site can also use layered services, so one visible provider name may not describe every control in the request path.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Enter a domain or full URL for a site you own or are authorized to review. Avoid using this check to probe systems without permission.
For a site you manage, compare any returned vendor label with DNS, hosting, and security-service configuration maintained by your team.
If results conflict, review response headers and service configuration through authorized administrative tools rather than treating one external observation as conclusive.
Use cases
See how the tool fits into real work and everyday tasks.
A site owner can compare a domain before and after a planned edge or hosting change, then confirm the intended protection in the provider account.
An administrator can use the result as a lead when documenting externally visible controls, then validate the inventory against internal records.
A consultant with authorization can note the returned indication and investigate deployment and rule coverage through the agreed assessment scope.
Q&A
Find concise answers to common questions and confusing cases.
No. A passive check can miss a firewall that does not expose recognizable signals, or that is deployed in a way the check cannot observe.
No. It is a possible product or provider identification, not a report of configured rules, coverage, or protection effectiveness.
Yes. Multiple services may sit at different points in a request path, and one visible signal may identify only one layer.
Only assess systems you own or have explicit authorization to review. Confirm findings through approved administrative access and the agreed scope.
Notes
Review scope, result limitations, and important precautions before use.
A positive or negative detection result does not verify firewall configuration, rule coverage, origin exposure, vulnerability status, or overall site security.
Network paths and security settings can change, and an external observation may be incomplete. Do not use this result as evidence of compliance or as a substitute for an authorized security assessment. Avoid submitting sensitive internal hostnames or systems outside your approved scope.
