CSP GENERATOR

What is Content Security Policy (CSP)?
Content Security Policy is a critical web security standard that acts as an additional layer of protection against cross-site scripting (XSS), clickjacking, and code injection attacks. By defining which content sources your browser should trust, CSP helps prevent attackers from executing malicious scripts on your website. Our CSP Generator simplifies the complex process of building secure policies by providing an intuitive visual interface for configuring 14 security directives, from script sources to frame ancestors. Whether you're securing a simple blog or a complex web application, you can create, test, and deploy CSP headers that protect your users without breaking functionality.

Features:

• 14 Security Directives: Configure default-src, script-src, style-src, img-src, font-src, connect-src, media-src, object-src, frame-src, worker-src, child-src, form-action, frame-ancestors, and base-uri
• Smart Security Presets: Choose from strict (maximum security), moderate (balanced protection), or permissive (easier implementation) starting configurations
• Report-Only Testing Mode: Test your CSP without blocking content by using report-only mode to identify violations before enforcement
• Multiple Output Formats: Generate HTTP headers for server configuration, HTML meta tags for static pages, or raw policy strings for custom implementation
• Custom Source Support: Add specific domains, nonces, hashes, or use keyword sources like 'self', 'unsafe-inline', and 'strict-dynamic'
• Modern Security Features: Enable upgrade-insecure-requests to automatically upgrade HTTP to HTTPS, and block-all-mixed-content for enhanced protection
• Real-Time Validation: See your CSP policy update instantly as you configure directives, making it easy to understand how each setting affects your security posture
• Copy-Ready Output: One-click copying of formatted headers ready to paste into your web server configuration, .htaccess file, or application middleware

Why Use a CSP Generator?
Manually writing Content Security Policy headers is error-prone and time-consuming. A single syntax mistake can either break your website's functionality or leave security gaps that attackers can exploit. Our CSP Generator eliminates these risks by providing visual controls for each directive, immediate feedback on your policy structure, and multiple testing options before deployment. Security teams, developers, and website administrators use this tool to implement defense-in-depth strategies that comply with OWASP recommendations and modern security best practices.

Best Practices for CSP Implementation:
Start with a strict policy using 'self' as your default source, then gradually add exceptions as needed. Always test in report-only mode first to catch violations without blocking content. Avoid 'unsafe-inline' and 'unsafe-eval' whenever possible, as they significantly weaken your security. Use nonces or hashes for necessary inline scripts instead. Monitor CSP violation reports to detect both legitimate issues and potential attack attempts. Remember that CSP is most effective as part of a comprehensive security strategy alongside HTTPS, secure headers, and regular security audits.
