# Fortgeschrittene Sicherheit { #advanced-security }

## Zusatzfunktionen { #additional-features }

Neben den in [Tutorial – Benutzerhandbuch: Sicherheit](../../tutorial/security/index.md){.internal-link target=_blank} behandelten Funktionen gibt es noch einige zusätzliche Funktionen zur Handhabung der Sicherheit.

# Seguridad Avanzada { #advanced-security }

## Funcionalidades Adicionales { #additional-features }

Hay algunas funcionalidades extra para manejar la seguridad aparte de las cubiertas en el [Tutorial - Guía del Usuario: Seguridad](../../tutorial/security/index.md){.internal-link target=_blank}.

Las siguientes secciones **no son necesariamente "avanzadas"**.

Y es posible que para tu caso de uso, la solución esté en una de ellas.

# Tutorial - User Guide { #tutorial-user-guide }

This tutorial shows you how to use **FastAPI** with most of its features, step by step.

Each section gradually builds on the previous ones, but it's structured to separate topics, so that you can go directly to any specific one to solve your specific API needs.

It is also built to work as a future reference so you can come back and see exactly what you need.

The key features are:

* **Fast**: Very high performance, on par with **NodeJS** and **Go** (thanks to Starlette and Pydantic). [One of the fastest Python frameworks available](#performance).
* **Fast to code**: Increase the speed to develop features by about 200% to 300%. *
* **Fewer bugs**: Reduce about 40% of human (developer) induced errors. *
