X-Frame-Options Header Test

What is X-Frame-Options?

Compatible with all major modern browsers, X-Frame-Options is a security header to prevent a well-known vulnerability called Clickjacking.

Put simply, Clickjacking is when a cybercriminal tricks you into clicking a malicious link on a legitimate-looking but compromised web page.

Based on the configuration, this header instructs the browser not to open a web page in a frame or iframe to avoid such risks.

These guides will help you achieve this in Apache HTTP, Nginx, F5, and WordPress.
