CSP Scanner: Test, Analyze & Evaluate CSP for Google Chrome

CSP Scanner - How to Test a Site’s Content Security Policy

Scanners like these are crucial to understand the way they work and to effectively block any type of CSF attack. Using the extension, you can safely and quickly test a given site’s Content Security Policy (CSP) and verify if it is actually protecting the site against XSS, Clickjacking, Formjacking, and other malicious attacks.

A CSP is the most critical control that all websites must follow. It is a security protocol that allows websites to distinguish between different requests that should be treated as safe and others that should be seen as a potential security threat.

However, with so many different CSPs to process, it can be a difficult task to verify if a website’s implementation is strong enough.

This is where CSP Scanner can help. It allows developers and security experts to easily inspect a site’s Content Security Policy (CSP) and understand if it serves as a strong mitigation against client-side attacks like XSS, Clickjacking, Formjacking, Data Exfiltration and more.
