WAF Bypass Tool is an open source tool designed to test the security of any Web Application Firewall (WAF). It helps security teams identify false positives and false negatives in WAF protections by using both predefined and customizable payloads. This means the tool can simulate various attack payloads to see if the WAF blocks them correctly or mistakenly allows them through, which is essential for improving WAF efficacy. The tool supports multiple vulnerability types because it tests the WAF's behavior against a wide range of payloads, making it a universal solution for WAF security analysis. This tool is valuable for red, blue, white, orange, and yellow teams engaged in web security testing and helps ensure that WAF configurations are neither too permissive nor too restrictive. The open source nature enables users to customize and extend payloads according to their specific testing needs, increasing its adaptability in various security environments.
