TeleGeography, a global telecommunications market research and consulting firm, has revealed that 35% of WAN managers implemented one or more elements of Zero Trust security and Secure Access Service Edge (SASE) on at least some of their company’s networks in 2021.
This is up from 8% in 2019, according to TeleGeography’s latest WAN Manager Survey.
TeleGeography’s latest survey, featuring analysis from 185 companies, reveals that close to 100% of respondents who had adopted Zero Trust security had Multi-Factor Authentication in place.
Single sign-on, remote user and device access policies, and privileged access management, were also popular Zero Trust security policies. User behaviour analytics were less widely adopted.
“An increase in remote work is a big factor – it’s definitely driving up demand for Zero Trust solutions,” said Greg Bryan, Senior Manager at TeleGeography. “With many companies making remote work a permanent structure, we expect Zero Trust adoption to continue to grow. Cloud adoption and local Internet breakouts have also been long-standing drivers of Zero Trust, in addition to SD-WAN.
“Just 8% of respondents were unfamiliar with Zero Trust in 2021, compared to one in five in 2019,” continued Bryan. “We also see fewer respondents who either had not started or were just beginning their implementation journey when asked about their deployment pipeline. Without a doubt, Zero Trust has not just progressed in awareness, but in adoption.”
