No Unsafe-inline is a WordPress plugin designed to strengthen website security by implementing a robust Content Security Policy (CSP). This plugin addresses common vulnerabilities such as cross-site scripting (XSS) by allowing users to manage and whitelist scripts and styles effectively. With features like nonce-based CSP activation and machine learning clustering for inline scripts, it streamlines the process of securing web pages without extensive manual configuration. It also supports multisite installations and provides detailed documentation to assist users in navigating its options.

The plugin captures scripts and styles from web pages, enabling users to whitelist legitimate content through an intuitive admin interface. It offers tools for managing external scripts, inline scripts, and event handler scripts, while also allowing the use of hashes and nonces for added security. Users can easily create and customize their CSP directives, ensuring that their WordPress site remains protected against various code injection attacks.
