# CSP (Content Security Policy) (CSP (política de seguridad de contenidos))

A security header your server sends to the browser listing exactly which sources of scripts, images and styles are allowed to run on your page.

**Example:** For example, a strict CSP blocks any unexpected third-party script from running in your visitor's browser even if someone tries to inject it.
