SD-WAN Steering Companies during Age of Digitization and Cloud Computing

Apart from a simpler WAN architecture and cost savings, the software-defined approach also offers deeper network visibility. With an increasing number of devices being connected to the internet and rising amounts of digital data being created, shared, and accessed, the incidence of cybercrimes is growing. This is why companies are modernizing their IT infrastructure to be able to monitor their network from end to end.

Additionally, this approach allows for the creation of security policies wherein the treatment to be met out to different kinds of internet traffic can be pre-defined. Such high levels of security have become more important than ever with the growing adoption of big data and the internet of things (IoT). As machines get embedded with sensors and get connected to the internet, they become an easy target for cybercriminals.

Moreover, using traditional WANs, connecting them to the internet and monitoring their operations become costly and complicated. Here, SDN simplifies networking and device security management, provides real-time network performance visibility, and integrates the functions of firewalls, unified threat management (UTM), application filtering, and other security layers. Despite all these benefits, SD-WAN is currently majorly used in North America, as it is a relatively new technology.

Other reasons for the dominance of the continent on the SD-WAN market are the presence of several companies that offer the associated infrastructure and software and of multinational companies that need this network architecture. In addition, with governments in the region investing substantially in 5G connectivity, the demand for such solutions is only going to rise in the years to come.

Hence, to secure the IT infrastructure in the face of the rising cybercrime and to gain better network capabilities, businesses around the world will likely move from traditional WAN to the software-defined approach.
