A recent report from GlobalData highlights that the transition from software-defined wide area network (SD-WAN) to secure access service edge (SASE) is reshaping enterprise connectivity strategies across Asia.
This shift is primarily driven by the demands of hybrid work environments, increased cloud adoption, and escalating security challenges that call for simplified, end-to-end architectures.
For over a decade, SD-WAN has revolutionised enterprise routing by enhancing operational efficiency and enabling the use of affordable broadband in place of traditional MPLS. Its advantages, including centralised management, policy-driven traffic handling, and support for Zero Trust Network Access (ZTNA), have significantly boosted its adoption among enterprises.
However, as cyber threats continue to evolve, the complexity of managing isolated branch security stacks has become untenable. Recognising this challenge, enterprises are increasingly gravitating towards SASE, which integrates SD-WAN with essential security features such as firewall services, secure web gateways, and threat protection into a cohesive, cloud-based platform. This consolidation is pivotal in modernising security measures at branch and remote locations.
“It has become evident that most SD-WAN implementations will now be tied to security. Networking and security have been merging for some time, and the rising number of cybersecurity incidents globally will only hasten this integration,” said Steven J. Schuchart Jr., principal analyst – enterprise security and infrastructure at GlobalData.
In 2025, notable strategic movements within the market have been observed, including HPE’s acquisition of Juniper and Arista’s purchase of VMware’s Velocloud SD-WAN. These developments are reshaping competitive dynamics, prompting enterprises to seek architectures that harmoniously consolidate routing, security, and policy enforcement while minimising reliance on MPLS.
Enterprises, under operational pressures and the necessity for cost management, are increasingly viewing SASE and SD-WAN as indispensable solutions to provide secure, consistent access within a single operational framework.
As Schuchart concludes, “Integrating cloud-delivered platforms that unify networking and security is imperative. Providers demonstrating capabilities in both SASE and SD-WAN are poised to lead this transformation and support enterprises as they modernise their edge infrastructure.”
