What is a Content Security Policy?

CSP is an HTTP header that tells browsers which sources of content are allowed to load on your page. It prevents cross-site scripting (XSS), clickjacking, and other code injection attacks.

CSP is a critical security layer that prevents malicious scripts from executing on your pages. It significantly reduces the risk of XSS attacks, one of the most common web vulnerabilities.

What directives does the tool support?

The tool supports all standard CSP directives including default-src, script-src, style-src, img-src, connect-src, font-src, frame-src, media-src, and more.

How do I implement CSP?

Add the generated CSP as an HTTP response header. You can also use a meta tag in your HTML, though the header approach is preferred for full functionality.

Will CSP break my website?

A restrictive CSP may block legitimate resources. Start with report-only mode to identify issues before enforcing. The tool helps you configure directives properly.
