Security Headers Scanner

What is this tool

The Security Headers Scanner is a powerful online tool that helps you analyze your website's HTTP response headers to identify missing or misconfigured security settings. These headers play a critical role in protecting your website and users from common threats such as cross-site scripting (XSS), clickjacking, and data injection attacks.

When a browser communicates with a server, it receives headers that define how the content should be handled. Security headers like Content-Security-Policy, Strict-Transport-Security (HSTS), and X-Frame-Options act as an additional layer of protection. This tool scans your website and provides a detailed report showing which headers are present, missing, or incorrectly configured.

Using the Security Headers Scanner is simple and does not require technical expertise:

Enter your website URL in the input field.
Click the Scan button to begin the analysis.
Wait a few seconds while the tool checks your HTTP response headers.
Review the results, including detected headers, warnings, and recommendations.

The tool will highlight issues clearly, making it easy for developers, website owners, and security professionals to take action.
