SDN Security—What is it and Why Should SMBs Care?

Small and mid-sized businesses (SBMs) have every reason to be interested in deploying software-defined networking (SDN) technology, because it offers capabilities such as dynamic, efficient network configuration that can enhance network performance and monitoring.

SDN is designed to address the static architecture of traditional networks, making networks more like cloud services and centralizing network intelligence in a single component by disassociating the forwarding process of network packets from the routing process.

Using SDN, companies can create and control virtual networks via software. Traditional networks, on the other hand, use dedicated hardware devices such as routers to control network traffic.

Growing Market

The concept of SDNs and other software-defined IT components has been around for years, but only recently has it hit the mainstream. The technology appears poised for a significant growth spurt.

A report by market research firm Expert Market Research (EMR) said the global SDN market was valued at about $9.2 billion in 2020, and is projected to increase at a compound annual growth rate of 25% between this year and 2027, reaching a value of about $35.6 billion by 2026.

SDN market growth is being driven largely by the rising demand for network bandwidth, an increase in the use of
