U.S. Enterprises Lead Global Adoption of Software-Defined Network Services

US leads global adoption of software-defined network services, driven by demand for flexible and secure networks. Small and medium enterprises benefit from cost-efficient, scalable SD-WAN solutions with consumption-based pricing. Integrated security solutions in network services respond to increasing digital threats, enhancing enterprise security. The US dominates the global market for SD-WANs, with Accenture, HCLTech, Orange Business, and Verizon Business emerging as leaders in ISG's comprehensive analysis.

The United States continues to lead the global adoption of software-defined network (SDN) services, driven by a growing demand for flexible and secure networks. According to a recent report by Information Services Group (ISG), enterprises across the U.S. are increasingly adopting SDN solutions to support digital transformation and competitive advantage [1].

The 2025 ISG Provider Lens® Network — Software-defined Solutions and Services report for the U.S. highlights that companies of all sizes are seeking more flexible, secure, and cost-efficient networks. The report notes that the U.S. is the largest consumer of software-defined wide-area networks (SD-WANs) and the source of highly advanced as-a-service offerings from system integrators and network providers that shape the global SD-WAN landscape [1].

SD-WANs are nearly ubiquitous in large U.S. enterprises, and many small and medium-sized companies have joined the migration. The report states that rigid legacy infrastructures hinder organizations' ability to adapt to new technologies, business requirements, and processes [1].

The ability of software-defined networks to support multicloud environments while reducing complexity is a major reason for their increasing popularity in the U.S. As companies continue to adapt their cloud strategies and embrace cloud-native technologies, SD-networking allows data and applications to flow securely and efficiently across cloud platforms [1].

Growing security threats have led many organizations to demand integrated security solutions, for which software-defined networking often provides the foundation. Companies want a single, secure attack surface from on-premises to cloud, incorporating encryption, access control, and threat intelligence. Many are combining SD-WANs with cloud-based security services to form secure access service edge (SASE) frameworks [1].

Small and medium-sized enterprises (SMEs) are embracing SD-networking to access network and security services without making substantial investments in hardware. Leading providers are meeting this demand with SME-specific solutions, especially scalable SD-WANs with consumption-based pricing models [1].

The report also explores other U.S. trends related to software-defined networking, including the rising importance of edge computing and enterprise 5G connectivity. The global SD-WAN market is projected to expand from USD 7.91 billion in 2025 to USD 21.67 billion by 2030, at a CAGR of 22.3% during the forecast period [2].

In the area of customer experience, HCLTech is named the global ISG CX Star Performer for 2025 among networking service and solution providers. The report names Accenture, HCLTech, Orange Business, and Verizon Business as Leaders in all four quadrants, highlighting their strong performance in managed SD-WAN services, SD-networks transformation services, edge technologies and services, and secure access service edge [1].
