Dell’Oro Group’s SASE & SD-WAN research tracks the global market as enterprises transition from legacy network and security architectures toward cloud-based, integrated solutions designed for a cloud-first, distributed environment. The reports analyze market growth, technology adoption, vendor positioning, and regional trends across SASE, SD-WAN, Security Service Edge (SSE), and Access Routers.
As enterprises support increasingly mobile users and internet-based applications, traditional siloed network and security architectures can struggle to deliver the required performance and security. In response, organizations are moving toward dynamic, integrated architectures that can adapt to changing threats and workloads.
SASE brings network connectivity and security into a cohesive framework, integrating SD-WAN’s performance-enhancing capabilities with SSE technologies, including secure web gateway (SWG), cloud access security broker (CASB), zero trust network access (ZTNA), and firewall-as-a-service (FWaaS). The research examines how enterprises adopt these technologies, how SASE architectures differ, and how vendors are positioning their offerings as the market evolves.
The convergence of networking and security is reshaping enterprise infrastructure strategies and competitive dynamics across the vendor landscape. Enterprises must determine whether to adopt unified or disaggregated architectures, single-vendor or multi-vendor solutions, and how SASE technologies complement or replace existing branch networking products.
Understanding these transitions helps equipment vendors, service providers, and financial institutions assess market opportunities, changing customer requirements, and the impact of SASE and SD-WAN adoption on established networking and security markets.
