This report analyzes the enterprise shift from mature SD-WAN deployments to SASE as cloud adoption, direct internet access, AI workloads, and distributed work dissolve the traditional network perimeter. Based on EMA research with 226 IT, security, networking, and business leaders, it finds SD-WAN is broadly implemented, with 73.5% using it in production, while more than 60% plan to complete SASE transitions within 12 months. Direct Internet Access is the leading WAN connectivity method, used by 77.4% of enterprises, making cloud-delivered security essential. The report emphasizes NetSec convergence, multi-vendor interoperability, ZTNA, predictive observability, and AI/ML automation, concluding that the next WAN transformation wave depends on intelligent, identity-driven SASE architectures.
