SD-WAN is an acronym for software-defined networking in a wide area network. SD-WAN simplifies the management and operation of a WAN by decoupling the networking hardware from its control mechanism.

An SD-WAN uses a centralized control function to securely and intelligently direct traffic across the WAN. This increases application performance, resulting in enhanced user experience, increased business productivity and reduced costs for IT. SD-WAN Brings Together Apps, Network, and Security at the Edge. Modern businesses need a network that can keep up with the pace of digital – one that delivers the best experience for the applications central to innovation and growth. Our next-generation WAN Edge solution delivers flexible, automated, secure connectivity and performance that keeps the workspace always-on

SD-WAN uses software- and cloud-based technologies to simplify the delivery of WAN services to the branch office. SD-WAN uses a virtual overlay to abstract the underlying network connections

Advantage of SD WAN

  • Increases application performance
  • Increases business productivity
  • Reduce cost for IT
  • Secure connectivity
  • Robust edge-to-edge security and micro-segmentation.


  • Improve Performance
  • Not all network traffic is created equal. SD WAN can be configured to prioritize business-critical traffic and real-time services like voice over Internet Protocol (VoIP) and then steer it over the most efficient route.

    By facilitating critical applications through reliable, high performance connections, IT teams can help reduce packet loss and latency issues, thereby improving employee productivity and boosting staff morale.


  • Lowers Complexity
  • Digital transformation initiatives can add layers of complexity to a network. The result is not only a risk of poor network performance, but over-taxed IT teams and the need for locating onsite personnel at remote sites to manage the local IT infrastructure.

    SD-WAN can ease the IT burden by simplifying WAN infrastructure, using broadband to off-load non-critical business apps, automating monitoring tasks, and managing traffic through a centralized controller. Consider looking for an SD-WAN solution that can also integrated into the local branch infrastructure to drive security and management deep into the local LAN.

  • Boosts security
  • Digital transformation is a double-edged sword. While it can improve customer satisfaction and extend market reach, it can also expose an organization to significant security risks. However, the basic firewall and VPN functions provided by most SD-WAN solutions are often not enough, forcing IT teams to try and overlay security across elastic and dynamic SD-WAN connections after the fact.

    A better option is to look for SD-WAN solutions that provide a wide range of integrated security features, such as NGFW, IPS, encryption, AV, and sandboxing capabilities that can help prevent data loss, downtime, regulatory violations, and legal liabilities.

  • Enables cloud Usage
  • Organizations are increasingly adopting cloud services. The good news is that SD-WAN enables direct cloud access at the remote branch, thereby eliminating backhauling traffic – routing all cloud and branch office traffic through the data center, meaning that workers can directly access cloud applications regardless of location without burdening the core network with additional traffic to manage and secure.

  • Reduces costs
  • As organizations deploy an ever-increasing array of cloud-based applications, the amount of data travelling over a WAN increases exponentially, increasing operating costs. SD-WAN can reduce this price tag by leveraging low cost local Internet access, providing direct cloud access, and reducing the amount of traffic over the backbone WAN.
