Secure SD-WAN
What is Secure SD-WAN
As the use of business-critical, cloud-based applications and tools continue to increase, distributed organizations with multiple remote offices are switching from performance-inhibited wide-area networks (WANs) to SD-WAN. SD-WAN is a software-defined wide-area network architecture. SD-WAN solutions transform an organization’s capabilities by leveraging the corporate WAN as well as multi-cloud connectivity to deliver high-speed application performance at the WAN Edge of branch sites. SD-WAN provides a centralized control mechanism that can determine and route the ideal path for traffic—MPLS, 3G/4G/5G, or broadband—ensuring organizations can quickly and easily access business-critical cloud applications. But SD-WAN solutions don’t provide in-built security which is critical for direct internet access. Secure SD-WAN enables organizations to enable NGFW with SD-WAN in simplified offering.

Secure SD-WAN Benefits
Evolving beyond the traditional WAN architecture with SD-WAN enables organizations to move past archaic MPLS services and open their networks to direct internet access. SD-WAN solutions not only allow organizations to reap the rewards of Software-as-a-Service (SaaS) applications, applications in public clouds, and unified communications, but it ultimately delivers a lower total cost of ownership (TCO).
How SD-WAN Works
An SD-WAN solution connects users to any application wherever it resides from data center to the cloud. SD-WAN intelligently determines which path best meets the ideal performance needs for a specific application. It then routes the traffic through to the ideal WAN path, whereas traditional WAN architectures only have the ability to route all applications through MPLS. Below are a few characteristics that define how an SD-WAN solution works and has evolved from a WAN infrastructure:
Application Awareness
With traditional WAN solutions, organizations suffer a less than ideal quality of experience and have a hard time delivering high-performance bandwidth for critical applications. Since legacy WAN architectures rely on packet routing, they lack in-depth application visibility. SD-WAN solutions, however, intelligently identify applications on the very first packet of data traffic. Network teams gain the visibility they need about which applications are used most widely across the organization, which helps them make smarter, more well-informed decisions and policies.
Multi-path Control
SD-WAN solutions enable three connections for traffic to flow through: an MPLS connection, a broadband connection, and an IPsec tunnel. The SD-WAN solution can intelligently identify applications and determine the best path it should take to maximize functionality. Moreover, multi-path technology automatically routes traffic to the next best available link in the event of an outage of the primary link. Not only does this automated capability reduce complexity within the network, but it delivers an improved user experience and improves performance of applications.
Zero-Touch Deployment
SD-WAN solutions provide control and data plane separation to ensure centralized management and orchestration. SD-WAN enables faster deployments with zero-touch provisioning capabilities while doing it at scale. In addition, a unified management console for both network and security operations helps to simplify operations at WAN Edge.
