About Security Headers

What are Security Headers?

HTTP security headers are directives sent by web servers to browsers that help protect against various security vulnerabilities. They provide an additional layer of security by controlling browser behavior and preventing common attacks.

Why are they important?

• Prevent XSS (Cross-Site Scripting) attacks
• Protect against clickjacking
• Enforce HTTPS connections
• Control resource loading and execution
• Prevent MIME type sniffing attacks

Note: This tool analyzes publicly accessible headers. Some headers may not be visible due to CORS policies or server configuration.
