ZPA Architecture Deep Dive | ZCC, Broker, Dispatcher & App Connector Explained

# ZPA Architecture Explained | Complete Packet Flow, Components & Zero Trust Access

In this video, we take a deep dive into the complete Zscaler Private Access (ZPA) architecture and understand how Zero Trust Network Access (ZTNA) works behind the scenes.

We start by comparing traditional remote access VPN architecture with ZPA and explain why organizations are moving away from network-level access towards application-level access.

You'll learn how ZPA provides secure access to private applications without exposing internal networks, server IP addresses, or client IP addresses.
