Traditional SD-WAN Is Not Zero Trust

Move to Zero Trust SD-WAN for secure branch connectivity.

Traditional SD-WAN enables lateral threat movement. Choose Zero Trust SD-WAN.

Zscaler Zero Trust SD-WAN connects sites by brokering ephemeral, least-privileged connections between users, devices, and apps.

The Problem

Traditional SD-WAN implicitly trusts all traffic, including attackers

With a mesh of site-to-site VPNs, traditional SD-WAN creates a flat routed network with implicit trust—enabling lateral threat movement.

  • A compromise at a branch can move rapidly through your entire network, resulting in a breach.
  • Network-based security policies add complexity and management overhead, yet fail to stop ransomware and other cyberattacks.
  • Multiple policies and tools across users, devices, and apps create security gaps and increase administrative burden.
