The CSP Generator for 3rd-Party Services eliminates the guesswork and frustration of creating Content Security Policy headers. Instead of manually researching which domains to whitelist for each service, simply check the third-party services your website uses (Google Analytics, Stripe, Intercom, etc.) and get a complete, secure CSP policy generated instantly. This tool covers dozens of popular services with their exact domain requirements, saving hours of documentation diving and trial-and-error testing.

How to Generate Your CSP Policy

Browse the service categories (Analytics, Payments, Security, etc.) and check all third-party services your website uses
Configure base settings like including "self", allowing data URIs, or unsafe-inline styles as needed for your setup
Add any custom domains in the "Custom Directives" tab for services not listed in the predefined options
Click "Generate CSP Policy" to create your complete Content Security Policy header
Review the generated policy and copy it to your clipboard or download as a configuration file
Implement the policy as an HTTP header (Content-Security-Policy) or HTML meta tag in your website
Test your website functionality to ensure all services work correctly with the new CSP policy
Fine-tune by adding additional domains or adjusting directives if any functionality breaks

Streamline Web Security Implementation

The CSP Generator transforms the complex task of creating Content Security Policy headers into a simple checkbox selection process. By providing pre-researched domain mappings for popular services, this tool eliminates hours of documentation reading, trial-and-error testing, and security policy debugging. The generated policies follow security best practices while ensuring your third-party integrations continue to function correctly. This approach reduces the risk of overly permissive policies that compromise security or overly restrictive policies that break functionality, making CSP implementation accessible to developers of all experience levels.

Web Security Applications

E-commerce Website Security

Generate CSP policies for online stores using payment processors like Stripe or PayPal, analytics tools, and customer support chat widgets.

Marketing Website Compliance

Create policies for marketing sites with tracking pixels, analytics, social media widgets, and lead generation tools while maintaining security.

SaaS Application Protection

Implement CSP headers for web applications using error tracking, user analytics, customer support tools, and authentication services.

Content Website Security

Secure blogs and content sites using CDNs for fonts and libraries, social media embeds, comments systems, and advertising networks.

Enterprise Security Compliance

Generate comprehensive CSP policies for enterprise applications that meet security compliance requirements while supporting necessary integrations.

CSP Implementation Best Practices

Start with a restrictive policy and gradually add necessary domains rather than beginning with permissive rules
Test your website thoroughly after implementing CSP to ensure all functionality remains intact
Use "report-only" mode initially to identify any blocked resources before enforcing the policy
Avoid "unsafe-inline" and "unsafe-eval" whenever possible as they significantly weaken XSS protection
Regularly audit and update your CSP policy when adding or removing third-party services
Use specific domains instead of wildcards to minimize the attack surface
Implement CSP violation reporting to monitor and identify policy violations in production
Consider using nonces or hashes for inline scripts and styles instead of unsafe-inline
Keep your CSP policy as minimal as possible - only include domains you actually need
Document your CSP policy and the services it covers for team members and future maintenance

Understanding Content Security Policy

Content Security Policy (CSP) is a security standard that helps prevent Cross-Site Scripting (XSS) attacks by controlling which resources browsers are allowed to load for a webpage. CSP works by defining a whitelist of approved sources for different types of content through directives like script-src (for JavaScript), style-src (for CSS), and img-src (for images). When properly implemented, CSP can effectively mitigate XSS attacks, data injection attacks, and clickjacking attempts. However, creating CSP policies manually is challenging because third-party services often load resources from multiple domains, and documentation may be scattered or incomplete. This tool solves that problem by providing pre-researched, service-specific domain mappings that ensure your CSP policy is both secure and functional.

CSP Generator FAQ

What is Content Security Policy and why do I need it?

Content Security Policy (CSP) is a security header that prevents XSS attacks by controlling which resources (scripts, styles, images) can load on your website. It's essential for modern web security and required by many compliance standards.

How do I implement the generated CSP policy?

You can implement CSP as an HTTP header "Content-Security-Policy: [policy]" in your server configuration, or as an HTML meta tag "<meta http-equiv='Content-Security-Policy' content='[policy]'>". The HTTP header method is preferred.

What if my website breaks after implementing CSP?

Start with "Content-Security-Policy-Report-Only" to test without blocking. Check browser console for violations, then add necessary domains to your policy. Always test thoroughly in a staging environment first.

Should I include "unsafe-inline" in my CSP policy?

Avoid "unsafe-inline" when possible as it weakens XSS protection. Instead, use nonces or hashes for inline scripts/styles, or move inline code to external files. Only use it as a last resort.

How often should I update my CSP policy?

Update your CSP policy whenever you add, remove, or change third-party services. Also review it periodically (quarterly) to ensure it remains current and secure.

Can I use wildcards in CSP policies?

While wildcards are allowed (*.example.com), they're less secure than specific domains. Use specific domains when possible to minimize attack surface. Avoid wildcards like https://* which are overly permissive.

What's the difference between report-only and enforce mode?

Report-only mode (Content-Security-Policy-Report-Only) logs violations without blocking resources, perfect for testing. Enforce mode (Content-Security-Policy) actively blocks violating resources.

How do I handle services not listed in this tool?

Use the "Custom Directives" tab to add domains for unlisted services. Check the service's documentation for required domains, or use browser developer tools to identify blocked resources during testing.
