The WAN continues to extend its growth, with the number of enterprises connecting to over 100 inter-regional sites growing by 50%, from 19% in 2020 to 28% in 2021, according to Aryaka.

This is coupled with continued application growth, with the number of enterprises stating that they've deployed over 500 distinct applications growing to 46%, compared to 32% in 2021.

Only 17% of respondents plan to conduct an SD-WAN/SASE-driven network refresh this year versus 29% in 2020.

Enterprises are less concerned that the WAN service won't address application performance, coming in at 36% this year, versus 43% in 2020, with corresponding drops in SLA concerns, technology maturity, and lack of skills.

Enterprise SASE deployment plans are accelerating, with 29% stating that they are already deploying what they consider to be a SASE architecture.

As part of a complete SASE architecture, the top capability identified was SD-WAN transport at 34%. And for deployment, over half state that they prefer a solution that includes technology from both their WAN vendor and security specialists, spanning across cloud and the edge.
