It works by sending both normal and potentially malicious HTTP requests, then analyzing the responses using pattern matching and heuristics to identify the specific WAF product and vendor. The tool maintains signatures for a large number of commercial and open-source WAF solutions, from major vendors like Cloudflare, AWS, and Microsoft to niche security appliances.\n\nThe tool is intended for security professionals, penetration testers, and system administrators who need to understand what security layers protect a target application. It has low install friction\u2014only requiring the requests library\u2014and runs on modern Python versions (3.10+). The project has been maintained since 2014 and remains actively developed, with recent releases and a stable codebase.","worth_installing":"Yes, if you are a security professional, penetration tester, or system administrator who needs to identify WAFs protecting web applications. The tool is actively maintained, has no known vulnerabilities, low install friction, and a permissive license. Install only if you have authorization to probe the target systems\u2014unauthorized WAF detection may violate computer fraud laws."},"id":"wafw00f","links":{"html":"https://skillfed.io/packages/wafw00f","md":"https://skillfed.io/packages/wafw00f.md","pypi":"https://pypi.org/project/wafw00f/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-01-26","license_spdx":"BSD-3-Clause","license_treatment":"permissive","name":"wafw00f","python_support":"supports_current","summary":"The Web Application Firewall Fingerprinting Toolkit"},"popularity":{"monthly_downloads":157487,"position":10755,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.4.2"}
