Zero Trust SD-WAN
Secure branch connectivity without the risk and complexity of routable networks
Traditional software-defined WAN
SD-WAN reduces network costs and simplifies WAN and local internet breakout management, but it doesn’t address some of the critical challenges of legacy hub-and-spoke network and castle-and-moat security architectures.


Internet Attack Surface
Every internet-facing firewall can be discovered and attacked.

Lateral Threat Movement
Site-to-site VPNs create a large routable network. A single infected device can infect everything on the network.

Routing Complexity
A mesh of site-to-site VPNs connecting branches, factories, and data centers increases routing and operational complexity.

Zero Trust SD-WAN
We pioneered the Zscaler Zero Trust Exchange™ as a highly available, globally distributed security service edge (SSE) that uses zero trust connectivity to secure branch, data center, and public cloud (IaaS/PaaS) communications over a non-routable WAN.

SD-WAN or Router
Link connectivity and failover (internet, cellular, and more)
Z-Connector
Sends and receives traffic to/from the Zero Trust Exchange using per-session TLS/DTLS tunnels

Minimize the internet attack surface
Private applications sit behind the Zero Trust Exchange, where they can’t be discovered or attacked from the internet

Eliminate lateral threat movement
Connections are made to applications, not the network

Reduce operational complexity
The Zero Trust Exchange uses business policies to broker connections over non-routable networks
Seven Elements of Highly Successful Zero Trust Architecture

We are enabling work from anywhere and want to achieve zero trust connectivity for all our branches and factories with IoT and OT systems.
Zero Trust SD-WAN will allow us to minimize our internet attack surface, prevent the lateral movement of threats on our network, and simplify branch connectivity.
This, in combination with policy automation and experience monitoring as part of the Zscaler platform, will help us achieve operational excellence.

Secure access service edge built on a zero trust architecture
Secure access service edge (SASE), a framework developed by Gartner, addresses edge connectivity and security requirements to guide enterprises through their digitalization journey. The Zero Trust Exchange provides the foundation for SASE adoption and secure digital transformation by enforcing the principles of zero trust.

The SASE framework emerged with the realization that hub-and-spoke network and castle-and-moat security architectures would inhibit digital transformation.
The 7 Pitfalls to Avoid When Selecting an SSE Solution
Flexible deployment
With the Zero Trust Exchange, you have the option to deploy SD-WAN as a routable or non-routable network.

Zscaler integrates with leading SD-WAN providers
API integrations automate tunnel creation to the closest Zscaler data center for simplified deployment.





Zero Trust SD-WAN use cases
Secure access for users, workloads, and devices to the internet and multicloud applications with zero trust connectivity from Zscaler.

Café-like branch offices
Enable users with zero trust access to all applications—internet/SaaS or private apps—over the internet.

Zero trust site-to-site connectivity
Eliminate complex site-to-site VPNs for app-to-app and machine-to-machine access.

Accelerated M&A IT integration
Simplify and secure integrations between workforces, app hosting environments, and shared resource access across your ecosystem.

Zero trust for server and IoT/OT connectivity
Enable your users, servers, and IoT/OT devices to communicate directly, independent of the underlying corporate network, VPN, or WAN.
