What are the Pros & Cons of SD-WAN?


SD-WAN networks are intended to be the next evolution of network technology. They are not free of defects. Its goal is to offer customers three crucial things that help them maintain their business: reliability, security, and quality of service.

SD-WAN architecture is intended to increase network flexibility and responsiveness, it is not the overall solution, as standards must always be respected. If you plan to adopt the software-defined approach to designing your architecture.



Here is a brief overview of the Pros and Cons of SD-WAN:

Benefits of using SD-WAN

SD-WAN networks will be the future of systems as we know them. Companies are rapidly adopting public clouds to meet business requirements and satisfy their customers. They offer many benefits to organizations.

It facilitates network operations through WAN optimization enabled by cloud management and automation. The centralization of the network control is done through the use of an SD network controller. The controller facilitates the implementation of corporate policies at headquarters and branches. Compression, tokenization, application proxies, caching, reduplication, and other techniques are used to make the WAN behave as if the data were moving through a local network.

It improves business applications and makes them more agile compared to older architectures. Administrators will have the ability to determine the minimum and maximum bandwidth.
Maximize user experience and the efficiency of cloud and SaaS applications.

Reduce costs, provide network independence in 3G / 4G, MPLS, etc.
Everyday tasks, such as provisioning and configuration, are automated on the network.
Next-generation firewall (NGFW) with malicious protection against cyber threats. Stateful packet inspections occur when they reach the perimeter of the firewall.

Drawbacks of SD-WAN:

  • Like any other network, SD-WAN networks are not perfect and have their shortcomings. Here are some of the disadvantages that you should keep in mind:
  • SD-WAN networks have not yet been fully adopted. At present, companies still have traditional connections to ensure continuity of internal and external operations. This is offset by the adoption of the hybrid solution.
  • You will need the IT staff to implement and manage this technical solution. If they fail, asking for outside help will be an expensive endeavor.
  • SD-WAN networks are immune to poor performance.
  • There is no real end-to-end quality of service if only SD-WAN provisions are used.SD-WAN providers tend to vary and generally do not meet what was initially intended for software networks.


Whether you work in the office or at home, SD-WAN is designed to meet the needs of your business wherever you are. Cost savings and security are offered in abundance with granular quality of service. IT teams must consider the entire network infrastructure before embarking on the transition to the SD-WAN.
