What Is the difference between SD-WANs and WANs?

Current WAN edge technologies are increasingly influenced by SD-WAN (software-defined wide area network) technologies. SD-WAN identifies business-critical applications and directs them over the most efficient route of the WAN.

WANs and SD-WANs vary in the following ways:



Application Performance

WAN architecture drives the traffic from the network edge via data centers for security checks before sending it to the network. This causes delays and issues with cloud performance.

SD-WAN identifies and prioritizes critical application traffic. The system can detect where to send each app’s traffic, and distributes it to the closest cloud inspection service.


Transports the traffic over MPLS (multiprotocol label switching) from branch routers to data centers.

Uses broadband and internet services, providing faster connectivity and extra bandwidth.

Management and Visibility

WAN architecture is typically siloed, which can be complicated when you need to orchestrate multiple licenses and vendors.

Uses a unified management approach, with centralized policy creation and visibility.


Typically uses a VPN (virtual private network) to create a secure tunnel and protect the data.

Integrates advanced security mechanisms such as IPS (intrusion detection systems).


WAN infrastructure requires investment in hardware and it is generally expensive to update or expand the network.

SD-WANs don’t require investing in hardware to scale or expand the network. Additionally, they use low-cost internet to transport information, thus they are cheaper than MPLS.

What are the advantages of having a modern WAN edge?

Transforming the WAN (wide area network) edge by adding SD-WAN (software-defined WAN) functionality can improve productivity, simplify WAN operations and allow for better digital transformation and transition to the cloud.

Some advantages of transforming WAN edge capabilities include:

  • Secure connection to cloud computing platforms and cloud-hosted applications.
  • Simplification of branch connectivity from the edge.
  • WAN features like TCP (transmission control protocol) optimization and application protocol optimization improve application performance.
  • More visibility and centralized network management.
  • Optimization of traffic according to applications - for instance, using API (application programming interface) support for Microsoft 365.
  • Improving limitations of WAN edge routers by using route learning protocol.
