Script Sentinel - CSP Generator

About

Generate accurate, production-ready Content Security Policy headers in seconds directly from your browser. Script Sentinel scans real web pages and produces CSPs you can deploy with confidence.

Implementing CSP correctly is difficult. Static generators and manual configuration often lead to broken scripts, blocked resources, and endless trial and error. Script Sentinel solves this by analyzing what a page actually loads and generating a policy based on real usage.

When you run a scan, Script Sentinel detects scripts, styles, fonts, images, frames, and network connections used by the page. Inline scripts and external domains are identified automatically, allowing you to create a modern CSP that protects against cross-site scripting and data injection attacks without breaking functionality.

The generated CSP can be used with common deployment targets including Nginx, Apache, Netlify, Cloudflare, and HTTP meta tags. This makes it easy to move from testing to production with minimal effort.

Script Sentinel is built with a privacy-first approach. The extension does not track users, collect browsing history, or run scans in the background. Scans are performed only when explicitly triggered by the user.

The extension works in conjunction with the Script Sentinel backend to perform advanced analysis and generate clean, readable CSP output. Advanced functionality is available at https://script-sentinel.com.

Script Sentinel is designed for web developers, security engineers, DevOps teams, and agencies who need accurate CSP headers without the risk and complexity of manual configuration. If you have struggled with CSP errors or broken sites, Script Sentinel provides a safer and faster way to secure your application.
