Traditional SD-WAN creates security risks and operational overhead
Traditional SD-WAN solutions use site-to-site VPNs and extend your network everywhere, expanding the attack surface and enabling the lateral movement of threats. Relying on a castle-and-moat security architecture, they increase cost and complexity and fail to protect organizations against cyberthreats such as ransomware.

Discover the Power of Zero Trust SASE
Watch the full keynote for our Zero Trust SASE innovations launch
Zero Trust SD-WAN eliminates lateral movement
Zscaler Zero Trust SD-WAN provides branches and data centers fast, reliable access to the internet and private applications with a direct-to-cloud architecture that provides strong security and operational simplicity. It eliminates lateral threat movement by connecting users and IoT/OT devices to applications through the Zscaler Zero Trust Exchange™ platform.
Branch traffic can be securely forwarded directly to the Zero Trust Exchange, where ZIA or ZPA policies can be applied for full security inspection and access identity-based control of branch and data center communications. Trusted application traffic can be sent directly across the internet with direct internet breakout.

Replace complex site-to-site VPNs with a simple direct-to-cloud architecture that improves application performance and increases productivity.
![Minimizes the internet attack surface](/_next/image?url=https%3A%2F%2Fcms.zscaler.com%2Fsites%2Fdefault%2Ffiles%2FcolumnsIconsModuleCard%2Ficon-attack-surface-decrease_0.png&w=128&q=75)
Legacy WAN solutions expose the VPN ports to the public internet making networks more vulnerable to attacks. With Zero Trust SD-WAN, private applications sit behind the Zero Trust Exchange, where they can’t be discovered or attacked from the internet.
![Prevents lateral threat movement](/_next/image?url=https%3A%2F%2Fcms.zscaler.com%2Fsites%2Fdefault%2Ffiles%2FcolumnsIconsModuleCard%2Ficon-lateral-movement_0.png&w=128&q=75)
Site-to-site VPNs create a large routable network, and a single infected device can infect everything on the network. With Zero Trust SD-WAN, connections are made directly to applications, not the network.

"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.”
—Rui Cabeço, Service Group Mgr., Outbound Connectivity, Siemens
The first Zero Trust SASE
SASE architectures built on traditional SD-WAN expand the attack surface and allow lateral threat movement, undermining the zero trust architecture. Zscaler Zero Trust SASE is built on Zero Trust SD-WAN and AI to reduce business risk and network complexity.
