TYPO3 security overview

TYPO3 takes security seriously—both in its Core development and through the work of the official TYPO3 Security Team. But security is not just a feature of the system. It is a shared responsibility that involves system administrators, integrators, editors, and developers.

This chapter outlines common risks and how to mitigate them. It also explains how the TYPO3 Security Team handles incidents and how to respond if your site is compromised.

Security is not a fixed state—it is an ongoing process. Protecting your site requires regular review, timely updates, and responsible access control.
