SYDNEY -- Enterprises across Asia Pacific are modernizing enterprise networks with internet-first managed services spanning network, security and cloud operations to improve performance, resilience and governance, according to a new research report published today by Information Services Group (ISG) (Nasdaq: III), a global AI-centered technology research and advisory firm.

The 2025 ISG Provider Lens® Enterprise Managed Network Services report for Asia Pacific finds that organizations are replacing legacy networks with software-defined wide area network (SD-WAN) and secure access service edge (SASE) architectures. As they expand distributed operations, enterprises face rising pressure to ensure consistent application performance, regulatory compliance and cyber resilience while controlling costs and managing skills shortages. These factors are accelerating demand for modern managed network models that support rapid change without sacrificing visibility or control.

“Networks are becoming a strategic foundation for digital operations rather than a static utility,” said Leon Platts, president, Network and Software Advisory, ISG. “As enterprises accelerate AI adoption, robotics, and automation, the network is critical for reliable performance, real-time decision-making and sustained productivity gains. Across Asia Pacific, organizations seek architectures that balance flexibility with predictable performance to support mission-critical workloads.”

Enterprises’ growing use of cloud-native applications and distributed workforces is increasing demand in Asia Pacific for internet-first SD-WAN and SASE architectures, the report says. These models reduce dependence on costly legacy circuits while improving agility across geographically fragmented environments. Organizations are using deterministic underlays only where required for regulatory, latency or resilience reasons. This approach allows enterprises to modernize incrementally while maintaining service consistency across markets with varying infrastructure maturity.

Enterprises in the region are turning to managed and co-managed network services as they address internal skills gaps and increasing multivendor complexity, ISG says. API-first, usage-based network-as-a-service (NaaS) consumption models are growing in importance as companies seek to modernize networks incrementally and shift spending from CapEx to OpEx, ISG says. Automation and AIOps are being applied to provisioning, application assurance and change management to reduce manual effort and error rates. Faster site deployments, lower total cost of ownership and more predictable network performance are among the enterprise benefits of these advances.

There is a growing market in Asia Pacific for local managed network service providers that specialize in operating within sovereign boundaries, the report says. These providers work closely with customers, especially government bodies and private players, offering flexible co-managed models that are aligned with local regulations. They often maintain wholesale arrangements with national telcos while providing intent-based provisioning and real-time observability for quick recovery.

“Successful enterprises are rethinking network operations as a platform capability that underpins growth, customer experience and cost efficiency,” said Yash Jethani, principal analyst, ISG Provider Lens Research, and lead author of the report. “Modern managed network models enable organizations to scale digital initiatives while maintaining governance and service assurance.”

The report also explores additional trends affecting managed network adoption in Asia Pacific, including the growing importance of automation-led operations and the need to address variable last-mile performance and the complexity of edge connectivity.

The 2025 ISG Provider Lens® Enterprise Managed Network Services report for Asia Pacific evaluates the capabilities of 63 providers across four quadrants: Managed Network Services Evolution, Managed Network Services — Local Specialist Providers, Managed Enterprise Connectivity Solutions (DIA, VoIP and VPN) and Network as a Service (NaaS).

The report names Accenture, GTT, NTT DATA, Orange Business, Singtel, Tata Communications, Telstra and Vodafone Business as Leaders in three quadrants each. It names PCCW Global and Verizon Business as Leaders in two quadrants each. BT, Data#3, Globe Business, Hitachi Digital Services, Interactive, KT, Logicalis, Maxis, Microland, SK Telecom, Spark NZ, StarHub, TCS, Telekom Malaysia (TM One), Vocus and Wipro are named as Leaders in one quadrant each.

In addition, Birlasoft, BT, HCLTech and Wipro are named as Rising Stars — companies with a “promising portfolio” and “high future potential” by ISG’s definition — in one quadrant each.

In the area of customer experience, Tata Communications is named the global ISG CX Star Performer for 2025 among Enterprise Managed Network Services providers. Tata Communications earned the highest customer satisfaction scores in ISG's Voice of the Customer survey, part of the ISG Star of Excellence™ program, the premier quality recognition for the technology and business services industry.
