What is SD-WAN?

Software Defined Wide Area Networking (SD-WAN) enables branch offices to optimize the use of local broadband connections and MPLS lines. SD-WAN uses smart routing to provide the appropriate bandwidth needed for each application, including more latency sensitive apps like Voice Over IP. With SD-WAN, the steady migration to cloud applications can be accommodated by routing traffic from a branch directly to the cloud without passing through the data center first. SD-WAN security manages everything through software on centralized consoles instead of on the physical locations of individual edge devices and infrastructures.

What is a SD-WAN

What is SD-WAN Security?

Despite the benefits of SD-WAN, connecting branch offices directly to the cloud significantly increases their security risk and security management costs. Since branches are not protected by data center security, they are exposed to sophisticated multi-vector Gen V attacks. For complete network protection, SD-WAN helps enterprises to maintain security software at a distributed network of branches where space is limited and there are minimal local IT resources.


The History of SD-WAN Security

The early transition to SD-WAN began as far back as the 1980’s, when some of the first Internet-based services began forming the framework for today’s enterprise SD-WAN. Many SD-WAN professionals, though, point that the main transition happened in late 90’s-early 2000’s, when multi-protocol label switching was created. As a result, this sparked the invention of WAN Optimization, which ultimately led to SD-WAN solutions. Consequentially, an increasing number of businesses are looking to adopt Software Defined Wide Area Networks (SD-WAN) security to boost their bandwidth utilization and strengthen their network security.


How Does SD-WAN Work?

SD-WAN uses software, implemented in the cloud or on-premises, to route traffic to cloud applications. In order to address common network problems such as packet loss, poor connection, and service outages, SD-WAN routes and manages cloud traffic from a dedicated location. SD-WAN assesses the incoming requests, and routes traffic efficiently to the necessary data center, branch, or application. SD-WAN helps organizations ensure that their scaling, distributed workforce has fast, safe, and easy access from every appropriate location.


Benefits of SD-WAN

  • SD-WAN allows branches to simply and efficiently connect to the data center and cloud applications
  • SD-WAN smart routing optimizes bandwidth needed for each data center or cloud application
  • SD-WAN flexible deployment either on-premises or in the cloud
  • SD-WAN enables you to optimize the use of less expensive local broadband and wireless connections and MPLS
