Content Security Policy Generator & CSP Scanner

Script Sentinel is a CSP Generator and Content Security Policy Scanner for modern websites

Generate a production-ready Content Security Policy (CSP) automatically by scanning your website for scripts, styles, images, fonts, frames, and network connections. Start with the Content Security Policy Generator or learn more about how the CSP Scanner works.

Intelligent Policy Generation: Script Sentinel automatically generates a hardened Content Security Policy (CSP) by analyzing real website behavior, protecting against XSS, injection attacks, and unsafe third-party scripts.

Customizable and Interactive: Users can refine and validate generated policies through an intuitive interactive builder, preview their effectiveness before deployment, and ensure policies align with both security needs and website functionality.

Easy Implementation and Export: Script Sentinel provides ready-to-use CSP headers compatible with various web servers and platforms, making it especially valuable for developers new to CSP, security teams auditing existing configurations, and DevOps teams automating security processes.

Chrome Extension for Instant CSP Generation: The Script Sentinel Chrome extension lets you scan any live webpage directly from your browser and generate an accurate Content Security Policy based on real network requests. Instantly detect unsafe directives, blocked scripts, and external resources, then copy a production-ready CSP header without leaving the page.
