# Content Security Policy (Admin Tools) {#admin-tools-csp}

[Content Security Policy](https://docs.typo3.org/permalink/t3coreapi:content-security-policy@12.4) declarations
can be applied to a TYPO3 website in frontend and backend scope with a dedicated
API.

This module handles
[Reporting of violations of the Content Security
Policy](https://docs.typo3.org/permalink/t3coreapi:content-security-policy-reporting@12.4). It is always available
but can only be [accessed via the backend](https://docs.typo3.org/m/typo3/tutorial-getting-started/12.4/en-us/Concepts/Backend/AdminTools/Index.html#admin-tools-access),
not the Install Tool.
