The "Chrome Security Auditor" isn t a standalone product, but rather The "Chrome Security Auditor" isn't a standalone product, but rather the comprehensive security auditing capabilities embedded within **Chrome's Developer Tools**.

It's an essential resource for web developers to identify and rectify common web security vulnerabilities. Key features include:

* **Security Panel:** Inspects TLS/SSL certificate details, highlights insecure origins, and detects mixed content (HTTP on HTTPS).
* **Network Panel:** Allows examination of critical security headers (e.g., Content-Security-Policy, HSTS, X-Frame-Options).
* **Console:** Reports real-time security warnings and Content Security Policy violations.
* **Lighthouse:** Provides automated audits for security best practices, like HTTPS enforcement.

This collective functionality empowers developers to build and maintain more secure, privacy-respecting websites.
