Approaching a decade since SD-WAN emerged as a networking technology, it is safe to say nearly all corporate network managers have at least heard of SD-WAN.
The COVID-19 pandemic forced IT infrastructure teams to accommodate remote work and accelerated the shift to cloud services. These changes in the underlay shifted the cybersecurity threat landscape and drove SD-WAN vendors and customers to focus more on security than ever before.
SD-WAN is becoming more complex, integrating SASE architectures and improving services to meet the needs of the WAN world.
When we first asked our WAN Manager Survey respondents about SD-WAN in 2018, interest was high, but few respondents had installed the technology or begun the rollout process.
Over the past four years, early adopters who finished their deployments have started to assess the impact, and more enterprises than ever are in the rollout stage. We’ve looked at the enterprise SD-WAN market every two years to see what has changed and solidified.
