Global telecommunications market research and consulting firm, TeleGeography, revealed that 35% of Wide Area Network (WAN) managers implemented one or more elements of zero trust security (ZTS) and Secure Access Service Edge (SASE) on some of their company’s networks in 2021.
TeleGeography’s latest WAN Manager Survey says that this is an increase from 8% in 2019.
TeleGeography’s latest survey analysed 185 companies and revealed that almost 100% of respondents who adopted ZTS had multi-factor authentication in place.
Other popular ZTS policies were single sign-on, privileged access management, and remote user and device access policies. User behavior analytics was not adopted much.
“An increase in remote work is a big factor. It’s definitely driving up demand for zero trust solutions. With many companies making remote work a permanent structure, we expect zero trust adoption to continue to grow,” said Greg Bryan, Senior Manager at TeleGeography. “Cloud adoption and local internet breakouts have also been long-standing drivers of zero trust, in addition to SD-WAN.”
The survey also mentions the top security vendors that WAN managers use to protect their networks. One third respondents are leveraging a mix of security vendors for their network security sourcing strategy. The most used security vendors for hardware-based internet security, as per the survey, are Palo Alto, Cisco, and Fortinet.
“It’s worth noting that, as adoption grows, we’re seeing the knowledge gap narrow. Just 8% of respondents were unfamiliar with zero trust in 2021, compared to one in five in 2019. We also see fewer respondents who either had not started or were just beginning their implementation journey when asked about their deployment pipeline,” Bryan added. “Without a doubt, zero trust has not just progressed in awareness, but in adoption.”
TeleGeography’s WAN Manager Survey represented companies with a median revenue of $10 billion. IT managers designing, sourcing, and managing U.S. national, regional, and global corporate WANs have rendered their responses for this survey. This latest report comprises 60 new responses across various industries collected in 2021.
