"The Competitive landscape assessment of SASE and SD-WAN report noted that over the past decade, SD-WAN transformed enterprise routing by offering operational efficiency, centralised management and the ability to use cost-effective broadband alongside or instead of legacy multi-protocol label switching (MPLS). It added that SD-WAN's single-pane-of-glass model, policy-driven traffic handling and support for zero-trust network access (ZTNA) have helped accelerate adoption."
"However, as threats evolved and branch security stacks became difficult to manage as isolated products, the analyst observed that the need for consolidation intensified. This created the foundation for SASE, bringing SD-WAN, firewall services, secure web gateways, CASB, ZTNA and threat protection into a unified, cloud-based platform. As a result, it said, SASE has become the focal point of branch and remote-location security modernisation."
Networking and security strategies are converging as hybrid work, cloud migration, and rising threats drive demand for simplified, end-to-end architectures. SD-WAN modernized enterprise routing by delivering operational efficiency, centralised management, policy-driven traffic handling, and support for zero-trust network access while enabling cost-effective broadband alternatives to MPLS. Escalating threats and complex branch security stacks increased demand for consolidation, leading to SASE, which integrates SD-WAN, firewall services, secure web gateways, CASB, ZTNA, and threat protection into a unified cloud platform. Enterprises increasingly seek identity-driven policies, end-user experience monitoring, and scalable cloud controls, prompting supplier reshuffling in 2025.
