Work has outgrown the network perimeter, but many security models haven’t caught up.

Legacy VPNs were never designed for today’s hybrid, cloud-first, AI-driven environments. They introduce complexity, expand attack surfaces, and create friction for users and IT teams alike.

This guide by Zscaler explores why leading organisations are moving beyond VPNs and adopting a zero trust access model that connects users directly to applications securely, seamlessly, and at scale.

In this whitepaper, you will learn how to:

• Why VPN-based access increases risk and limits visibility in modern environments
• How zero trust shifts security from network-level to identity- and context-based access
• What it takes to eliminate lateral movement and reduce the attack surface
• How Zscaler Private Access (ZPA) enables secure, direct user-to-app connections
• Ways to simplify operations while improving user experience and performance
