Today, nearly half of the world’s population has internet access. As this figure grows, so too will the complexity of networks and connectivity. To keep pace, ongoing innovations in information technology are increasing the efficiency and reliability of these ever-expanding networks. Software-defined networking, or SDN, in particular, has changed the way information moves around the world.

Using the CB Insights Platform, we surfaced 18 notable network technology startups developing systems to increase the reliability, efficiency, and security of data mobility while reducing costs. These companies vary widely in their offerings, but generally leverage software to manage network functionality.
