CSP Evaluator is a tool that allows developers to check if a Content Security Policy (CSP) serves as mitigation against XSS attacks
CSP Evaluator is a small tool that allows developers and security experts to check if a Content Security Policy (CSP) serves as a strong mitigation against cross-site scripting attacks. Reviewing CSP policies is usually a very manual process and most developers are not aware of CSP bypasses.
CSP Evaluator checks are based on a large-scale empirical study and are aimed to help developers to harden their CSP. This tool is provided only for the convenience of developers and Google provides no guarantees or warranties for this tool.
