The Benefits of SD-WAN

The Benefits of SD-WAN

Managing a company with many branches spread out is not easy. Especially if the branches have data and networks that must always be connected to each other. To connect the networks between branches, many companies still use traditional WAN.

This network works by connecting branch offices and headquarters using routers through leased line connections or usually MPLS.

All applications will be hosted in the data center and routing is based on TCP Address, access control lists, and routing protocols that are quite complex. To support the smooth operation of the connection on a traditional WAN, IT infrastructure and supporting IT teams are needed with no small cost.

Why Are Many Companies Starting to Switch to SD-WAN?

Currently, the use of traditional WAN is no longer considered effective since the increasing use of cloud or cloud-centric infrastructure. To adapt to technological developments and the needs of companies, SD-WAN is now used.

SD-WAN or Software Defined Wide Area Network is the flexible and intelligent management of networks by utilizing software and centralized control functions.

With SD-WAN, network administrators or network managers are able to manage the network centrally and monitor all traffic.


Advantages of SD-WAN

There are various advantages of SD-WAN over traditional WAN, namely:

  • Cost

SD-WAN technology can eliminate the relatively expensive MPLS circuit costs and replace them with other connection options such as broadband and DSL. However, if necessary and conditions permit, the company can still use it.

  • High bandwidth

SD-WAN is supported by a collection of high bandwidth provided by several providers. This technology allows the transmission of large amounts of data simultaneously because it does not depend on a single transportation route.

  • Flexibility

SD-WAN also allows companies to expand their network area, both on-premise and cloud, with costs in accordance with their growth. For example, when a company opens a new branch.

  • Supporting cloud

Currently, more and more companies are using cloud and SaaS (software-as-a-service) to support their performance. SD-WAN is designed to support the changing needs of these companies. SD-WAN can support applications hosted on on-premise data centers, public and private clouds, and various SaaS services.


Why is SD-WAN More Secure?

Security is one of the main challenges in network management. According to, the basic security that is generally used by SD-WAN utilizes IPsec and VPN. The goal is to ensure that there is no interference from third parties during data transmission.

NGFW (Next Generation Firewall) is also one of the keys to SD-WAN security. NGFW is a virtualized version and an upgrade version of traditional hardware-based firewalls. This firewall is applied to branch offices and headquarters to perform various functions, namely:

  • Recognizing applications
  • Detecting and preventing intrusions
  • Filtering website and URL content
  • Detecting malware
  • Antivirus protection

Based on the explanation above, SD-WAN is very suitable for use in growing companies that have many branches and work by utilizing SaaS or cloud. So, if your company is included in this, don’t hesitate to switch to using this technology for your network management.
