HTTP Header Checker

What is the HTTP Header Checker Tool?

HTTP Header Checker helps you analyze the security headers of a website. Security headers are HTTP response headers that enhance the security of web applications by helping protect against various types of attacks.

Here’s what the tool does:

Analyzes Security Headers

It inspects the HTTP response headers of a website to check for the presence and configuration of security headers. These headers include:

• Content-Security-Policy (CSP): Helps prevent cross-site scripting (XSS) and other code injection attacks;
• Strict-Transport-Security (HSTS): Enforces secure (HTTPS) connections to the server;
• X-Frame-Options: Prevents clickjacking by controlling if the site can be embedded in iframes;
• X-Content-Type-Options: Stops browsers from interpreting files as a different MIME type;
• X-XSS-Protection: Provides basic XSS protection (though it’s often considered obsolete).

Provides Security Scores

The tool generates a score or grade based on the configuration of these security headers. This helps you quickly understand how well your site is protected against common security vulnerabilities.

Offers Recommendations

It provides actionable recommendations on how to improve your website’s security headers. This guidance can help you enhance your site’s protection by configuring headers correctly or adding missing headers.

Displays Detailed Reports

You receive a detailed report on each security header’s configuration, including the current settings and potential issues. This report helps you understand specific security aspects of your site and how to address them.

By using this tool, you can assess your website’s security posture, identify potential vulnerabilities related to security headers, and implement best practices to safeguard your web applications.
