Networking has historically been hardware-centric, with organizations deploying stacks of routers, switches and security appliances. The result is a highly complex environment that is managed manually on each device. Inflexible legacy network architectures make it difficult to implement new applications and services or scale the environment to meet changing demands.
The sudden shift to remote work models has revealed weaknesses in many corporate networks. In an IDC study of enterprise networking decision-makers conducted in May and June of 2020, 84 percent of respondents said employees are unable to access applications at least weekly due to network connectivity issues. More than half (51 percent) said employees cannot access applications multiple times a week, with 11 percent reporting that this problem occurs daily.
