Unsure about a website's security protection? Our tool helps you quickly identify whether a target website has a Web Application Firewall (WAF) deployed and outputs specific type and vendor information. A Web Application Firewall (WAF) is a security product dedicated to protecting web applications from attacks like SQL injection and XSS by analyzing HTTP/HTTPS traffic characteristics. Simply enter a website domain, and this tool will automatically probe response headers and content features, outputting a detection results table to assist with security analysis and penetration testing.
How does WAF detection work?
It identifies WAF fingerprints by analyzing the target website's response headers, content delays, and error characteristics. Different products have unique identifiers.
Are the detection results accurate?
They are not 100% accurate. Some WAFs have hidden or disguised configurations that may lead to missed detections. We recommend trying multiple times to verify.
The input domain should include the protocol header (e.g., https://) to improve accuracy. Results are for reference only and may be affected by network fluctuations. Please use this tool legally and avoid unauthorized scanning. No privacy data will be stored.
To improve detection accuracy, we recommend using a complete URL input, such as https://example.com. A typical output example: entering https://cloudflare.com will detect the WAF as Cloudflare and the vendor as Cloudflare Inc. This helps security teams quickly assess protection configurations.
