Forrester Wave Analysis

Forrester views standalone SD-WAN as a transitional technology that is rapidly being absorbed into broader frameworks like Zero Trust Edge (ZTE) and Secure Access Service Edge (SASE)

IDC MarketScape

AI and Distributed Traffic: IDC notes that AI workloads are redrawing wide area networks (WANs), making traffic more distributed, less predictable, and highly sensitive to latency. SD-WAN's ability to dynamically steer traffic makes it foundational for AI-ready architectures.

Gartner defines software-defined wide area networking (SD-WAN) as technology that connects branch offices to other enterprise and cloud locations using centralized management and dynamic path selection.

Key Benefits: Lower Costs: Cuts wide area network expenses by replacing or supplementing expensive dedicated circuits with standard internet.Better Performance: Prioritizes mission-critical business applications to prevent lag or downtime.Simplified Operations: Uses zero-touch provisioning to get remote sites online quickly without manual configuration.

Beyond Cost Cutting: Forrester notes that initial SD-WAN adoption focused heavily on simplifying routing and cutting WAN or MPLS costs using standard internet links. However, standalone setups exposed significant remote-site security challenges. Convergence of Security and Networking: Forrester originally championed the Zero Trust Edge Model (ZTE) to merge SD-WAN with security tools like Zero Trust Network Access (ZTNA) and Cloud Access Security Brokers (CASBs). Shift to SASE: Forrester transitioned its terminology from ZTE to Secure Access Service Edge (SASE) to match broader industry alignment around single-vendor or tightly integrated cloud-and-hardware security and networking platforms

IDC insights show that the worldwide SD-WAN infrastructure and managed services market is rapidly expanding, driven heavily by next-generation AI workloads, cloud connectivity, and integrated security
