SecuriScan is a lightweight Chrome extension designed for quick security analysis of websites. It provides developers with an accessible tool to identify common vulnerabilities and misconfigurations without the need for complex setups. The extension performs a comprehensive scan that evaluates security headers, cookie security, and known vulnerable JavaScript libraries, resulting in a security score from 0 to 100. Users can click on specific categories to view findings and receive guidance on remediation, making it ideal for frontend developers, security engineers, and students learning about web security.

The tool operates entirely within the browser, ensuring that no data is transmitted externally, which enhances user privacy. SecuriScan is built on Manifest V3 and operates with minimal permissions, emphasizing transparency and security. Although it is not a substitute for comprehensive security audits or penetration testing, SecuriScan serves as an effective initial health check for websites, providing users with valuable insights into their site's security posture.
