What is SD-WAN?

SD-WAN is the application of software based network technologies that virtualize WAN connections. SD-WAN decouples network software services from underlying hardware to create a virtualized network overlay. Enabling users anywhere to connect to applications anywhere, SD-WAN offers flexibility, simplicity, performance, security, and cloud scale. It also boasts ease of deployment, central management and control and assured application performance. SD-WAN is an essential component of Secure Access Service Edge (SASE) architecture.

2023 Gartner® Magic Quadrant™ for SD-WAN

For the sixth consecutive year, VMware is a leader in the Gartner® Magic Quadrant™ for SD-WAN.

Why VMware SD-WAN?

By optimizing traffic over multiple available connections, SD-WAN delivers a better user experience, anywhere. SD-WAN dynamically steers traffic to the best available link and remediates if transmission issues arise to ensure high performance of applications.

Performance and Reliability

Deliver high performance WAN reliability, transport, and provider flexibility to assure optimal performance even for demanding cloud and datacenter delivered applications, such as voice and video.

Realize Your Multi-Cloud Strategy

Connect users and branches securely and simply to the cloud through an optimized direct path to public and private enterprise clouds.

Build Your Foundation for Edge Digital Transformation

SD-WAN is now foundational to the distributed enterprise edge — not just for building a hybrid WAN or cloud connectivity. VMware SD-WAN enables seamless insertion and chaining of virtualized services on-premises and in the cloud to enable customers to digitally transform their business operations at the edge.

Enjoy Orchestration and Flexibility

Centralized monitoring, visibility and cloud control enable zero-touch branch deployment with support for many popular Secure Service Edge providers and VNF applications, allowing you to choose how and when you will transition to SASE.

Benefits of SD-WAN

SD-WAN solves network complexity while cutting total cost of ownership. SD-WAN simplifies operations through rapid zero touch provisioning and cloud management, optimizes app performance over any WAN link, accelerates cloud adoption through managed on-ramps, and offers robust edge security.

Enables Migration To the Cloud

SD-WAN delivers hybrid, multi-cloud, and SaaS functionality to support the needs of businesses today.

Simplified WAN Operations

Branch and remote site deployments are made simple with global WAN visibility, agility, and scale delivered through an automated platform.

Confidently Deploy a Hybrid Workforce

SD-WAN connects any device or any user to any application anywhere, in the cloud, at the edge, or in the data center with in-depth network analytics and security.

Comprehensive Edge Security

Cloud security is paramount to SD-WAN and achieved through end-to-end segmentation, advanced threat protection, and security VNFs via the SD-WAN platform.

Frequently Asked Questions

SD-WAN stands for software-defined wide area network (WAN).

SD-WAN offers flexibility compared to VPNs. It enables optimized traffic routing over multiple transport media, such as MPLS, cellular/5G or broadband, depending on the business need. VPNs are typically designed to send all traffic over a single network link.

MPLS is expensive and inflexible compared to SD-WAN. MPLS takes longer to deploy and is not built for the cloud. It requires backhaul through the data center, which slows traffic and negatively impacts the user experience.

SD-WAN adds enhanced security and control to the network. Traditional WAN is an unencrypted VPN and requires security add-ons.

Secure Access Service Edge (SASE) combines cloud networking with cloud security to transform organizations to better support workers in multiple locations (office, home, airport,…), applications in many locations (cloud IaS, SaaS, datacenter, edge,..) and operational transformations at edge sites.

The security side of SASE is called Secure Service Edge (SSE). The network side is provided by SD-WAN and is critical to a SASE architecture.
