HomeGlossary TermsX-Frame-Options


An HTTP header that helps protect against clickjacking attacks by specifying whether a browser should be allowed to render a page in a frame or iframe. It enhances web security.

Imagine you're building a fortress to protect your website from potential intruders. One of the tools you'd use is called X-Frame-Options. Essentially, it's like setting up a security gate to control who can and cannot frame your website within their own web pages.

Let's break it down. When someone tries to embed your website into their page using a frame or iframe, they might have good intentions, like showcasing your content or services. However, sometimes, these frames can be exploited by malicious actors to carry out attacks like clickjacking, where they trick users into clicking on something they didn't intend to.

Now, by setting up X-Frame-Options, you're telling web browsers how your site should behave when it's being framed by another site. You have three options:

  1. DENY: This is like putting up a "Do Not Enter" sign. It means your site cannot be framed by any other site, no exceptions. This is the most secure option but might limit legitimate uses of framing, like embedding your content on partner sites.
  2. SAMEORIGIN: With this option, you're allowing your site to be framed, but only by pages from the same origin. In other words, only if the framing page is from your own domain or subdomain. It's like saying, "Sure, you can come in, but only if you're from around here."
  3. ALLOW-FROM uri: This option lets you specify specific URLs that are allowed to frame your site. It's like having a guest list at a party – only certain sites are invited to frame your content.

By using X-Frame-Options, you're adding an extra layer of protection to your website, safeguarding it against potential security threats while still allowing legitimate use cases for framing. It's a simple but effective way to keep your digital fortress secure.
