wafw00f

wafw00f is a specialized tool within Canva workflows that identifies Web Application Firewall (WAF) products for specified URLs. Its primary role is to enhance security assessments by detecting WAF technologies that may protect web applications, thus informing subsequent actions in automated security workflows.

Ideal Use Cases & Fit​

This tool excels in scenarios requiring the identification of WAFs for multiple URLs in a single pass. It is particularly effective in pre-penetration testing phases, where understanding the protective measures of web applications is crucial. The typical input format includes newline-separated URLs, such as:

https://example.com
https://example2.com

wafw00f is not suitable for real-time network intrusion detection or situations where high-speed scanning is critical, as its focus is on comprehensive WAF detection rather than rapid enumeration.

Value in Workflows​

Incorporating wafw00f in security workflows adds significant value by providing insight into the defensive mechanisms employed by web applications. This information can be vital for early reconnaissance phases, allowing security teams to adapt their testing strategies appropriately. As part of an automated workflow, it can serve as a preprocessing step before deeper security assessments, ensuring that all actions are informed by the current security posture of the applications involved.

Input Data​

The tool requires input data in the form of a file containing newline-separated URLs. This format allows for easy bulk processing of multiple targets, facilitating efficient WAF identification.

Example:

https://example.com
https://example2.com

Configuration​

  • format: Specifies the output format of the results (e.g., csv, json, text), with a default value of json.
  • proxy: Defines the HTTP proxy to use when making requests, which is essential for scenarios requiring traffic monitoring or obfuscation.
  • find-all: Controls whether to find all available WAFs without halting on the first detection (default is false).
  • no-redirect: Prevents following redirects from 3xx responses, reinforcing the focus on direct WAF responses (default is false).
  • timeout: Sets the request timeout period, ensuring that the tool doesn't hang on slow responses.
  • headers: Allows for inclusion of custom headers as specified in a text file, which can be useful for simulating specific client behaviors.
  • no-colors: Disables ANSI colors in the output to ensure compatibility with various output formats. Updated: 2026-02-10
