X-Frame-Options & Clickjacking Prevention Guide

Clickjacking attacks trick users into clicking invisible iframe overlays placed over legitimate UI buttons (e.g. "Delete Account" or "Transfer Funds"). Enforcing X-Frame-Options headers eliminates framing risks.

Frequently Asked Questions

Common questions about this tool.

What is the X-Frame-Options header? ▼

The `X-Frame-Options` HTTP response header indicates whether a browser should be allowed to render a page inside a `<frame>`, `<iframe>`, `<embed>`, or `<object>` tag, protecting against clickjacking.

What is the difference between DENY and SAMEORIGIN? ▼

`DENY` blocks all framing attempts across any domain (including your own). `SAMEORIGIN` permits framing only if the embedding site shares the exact same origin domain.

How does CSP frame-ancestors relate to X-Frame-Options? ▼

`Content-Security-Policy: frame-ancestors` is the modern replacement for `X-Frame-Options`. However, serving both headers ensures protection across legacy browsers.

Why is ALLOW-FROM deprecated? ▼

The `ALLOW-FROM uri` directive is deprecated by modern browser standards and unsupported in Chrome/Safari. Use CSP `frame-ancestors uri` instead.

How do I add X-Frame-Options in Nginx? ▼

Add `add_header X-Frame-Options "DENY" always;` or `add_header X-Frame-Options "SAMEORIGIN" always;` in your Nginx server block.
