# Overview

{% hint style="info" %}
**Optional for Most Installations**

This section covers advanced and optional topics. Most installations do not require these settings. Only proceed here if you have specific requirements for scaling, security hardening, or infrastructure optimization.
{% endhint %}

## Overview

Advanced Topics covers optional configurations for:

* **Scaling Infrastructure**: Load balancing, caching, performance optimization
* **Security Hardening**: SSL, CSRF protection, trusted proxies

**When you might need this section:**

* Running PteroCA at enterprise scale (100+ concurrent users)
* High-security requirements
* Custom infrastructure setup
* Performance optimization needs

**When you DON'T need this section:**

* Standard PteroCA installation
* Small to medium hosting businesses
* First-time setup

## Topics Covered

### [Scaling Infrastructure](/advanced-topics/scaling-infrastructure.md)

Optimize PteroCA for high-traffic scenarios:

* Load balancing across multiple servers
* Redis caching for performance
* Database optimization
* CDN integration for static assets

**When to use**: 100+ concurrent users, multiple app servers

### Security Hardening

Additional security configurations beyond basic security settings:

#### [SSL Configuration](/advanced-topics/security-hardening/ssl-configuration.md)

* Configure HTTPS/SSL
* Force HTTPS redirects
* SSL certificate management

**When to use**: Production environments (strongly recommended)

#### [CSRF Protection](/advanced-topics/security-hardening/csrf-protection.md)

* Understanding CSRF tokens
* Configuring CSRF protection
* Troubleshooting CSRF errors

**When to use**: Already configured by default, this explains how it works

#### [Trusted Proxies](/advanced-topics/security-hardening/trusted-proxies.md)

* Configure trusted proxy IPs
* Fix client IP detection behind proxies
* CloudFlare integration

**When to use**: PteroCA behind reverse proxy, load balancer, or CloudFlare

## Prerequisites

Before diving into advanced topics:

* ✅ Complete basic installation: [Installation](/installation/installation.md)
* ✅ Core configuration finished: [Core Configuration](/core-configuration/core-configuration.md)
* ✅ System is working correctly
* ✅ You have identified a specific need for advanced configuration

## Do You Really Need This?

**You might need advanced configuration if:**

* You're experiencing performance issues with many concurrent users
* You have specific security compliance requirements
* You're running a complex infrastructure setup
* You're behind a reverse proxy or load balancer

**You DON'T need advanced configuration if:**

* Your installation is working fine
* You have < 100 concurrent users
* You're just getting started
* You haven't identified specific issues
