What is SD-WAN?

Software-Defined Wide Area Networking, or SD-WAN, is a technology that allows organizations to route and manage traffic across a wide area network (WAN) with software-defined networking, rather than with hardware such as routers and switches.

With SD-WAN, enterprises can reduce networking costs by using any combination of connection types – including MPLS, LTE and broadband internet services – to connect remote users with applications and IT resources. SD-WAN technology can also improve performance by routing traffic more efficiently to optimize speed and bandwidth.

SD-WAN plays a crucial role in cybersecurity by enabling security functions to be distributed to branch and remote endpoints rather than requiring traffic to be backhauled to a central data center for inspection.

SD-WAN uses software-defined networking (SDN) technology to create an overlay that virtualizes and abstracts network connections. This allows agnostic use of different connection types – the network can use standard MPLS connections alongside broadband and mobile networks for greater flexibility. Differences between connectivity types are minimized; data can be sent through any connection using tunnelling technology.

SD-WAN also enables centralized orchestration of network configuration and policies, significantly increasing efficiency and providing greater visibility for IT teams. Application-aware routing enables traffic to be routed with optimal bandwidth and speed to meet the demands of applications while ensuring that business-critical functions receive priority.

With the ability to use faster, lower-cost local internet connections at remote locations, enterprises can rely on SD-WAN to:

• Improve user experiences. With SD-WAN, users at remote sites can access the resources they need with lower latency, better performance and greater reliability.
• Simplify management. Centralized management enables network operations teams to monitor branches and remote sites globally.
• Enhance reliability. SD-WAN enables automatic failover, routing traffic around links that have failed or are congested.
• Reduce costs. Expensive MPLS lines can be augmented or replaced with affordable commodity connections like DSL, cable and fiber.

Most SD-WAN solutions include encryption to protect data privacy. But without integrated security, this connectivity option can be another attack vector. Superior SD-WAN technologies provide additional security capabilities as well.

As remote users connect directly to cloud applications, security that once was provided by centralized, on-premises gateways must now be enforced at each remote location or in the cloud. Secure SD-WAN solutions make this possible by incorporating key security features:

• Access control and intrusion prevention technology, typically through Next-Generation Firewalls (NGFW), prevent attackers from penetrating defenses.
• Web security features deliver real-time protection against advanced threats within web pages or downloaded content.
• Cloud monitoring solutions track and protect apps and data stored in the cloud to prevent abuse.

With superior SD-WAN solutions, enterprises can enable users to seamlessly connect to the cloud resources they need while protecting networks, users, and data from theft, loss and attack.
