ISG to Study Enterprise Managed Network Service Providers

(Neutral)

(Very Positive)

Key Terms

network as a service technical

Network as a service is a subscription-based offering where companies rent managed networking functions—such as connectivity, routing, security and performance monitoring—delivered over the internet instead of buying and running physical hardware themselves. It matters to investors because it creates predictable recurring revenue for providers and lets customers shift big upfront technology costs into pay-as-you-go expenses, much like renting electricity instead of building a power plant, which can boost scalability and profit visibility.

naas technical

NaaS (Network-as-a-Service) is a cloud-based model that lets businesses rent networking functions — such as connecting sites, directing internet traffic, and applying security controls — on a subscription basis instead of buying and managing physical equipment. Investors watch NaaS because it turns large, unpredictable hardware sales into steady recurring revenue and often higher margins, making cash flow more predictable and growth easier to value, much like a subscription service replacing one-time purchases.

multicloud technical

Multicloud is the practice of a company using cloud computing services from two or more different providers instead of relying on just one, like keeping money in several banks so you can use each bank’s strengths. For investors, it matters because it can lower operational risk, improve reliability and flexibility, and affect costs and growth prospects — all of which influence a company’s profitability and competitive position.

predictive analytics technical

Predictive analytics uses historical data and patterns to estimate future outcomes, like sales, customer behavior, or operational problems. For investors it matters because it turns past signals into probable forecasts—similar to a weather forecast or traffic app—helping assess potential risks, spot opportunities, and prioritize where to allocate capital, while remembering that predictions carry uncertainty and are not guarantees.

Upcoming ISG Provider Lens^® report will evaluate providers helping organizations modernize network environments for distributed enterprise operations

STAMFORD, Conn.--(BUSINESS WIRE)-- Information Services Group (ISG) (Nasdaq: III), a global AI-centered technology research and advisory firm, has launched a research study examining service providers that enable organizations to strengthen network resilience, modernize operations and prepare infrastructure for the demands of AI-enabled business.

The study results will be published in a series of comprehensive ISG Provider Lens^® reports, called Enterprise Managed Network Services, scheduled to be released in December 2026. The reports will cover companies offering services including network transformation, managed network operations, network as a service (NaaS) and managed enterprise connectivity services.

Enterprise buyers will be able to use insights from the reports to evaluate their current vendor relationships, identify potential new engagements and compare available offerings. ISG advisors will use the research to guide clients through increasingly complex transformation and platform investment decisions.

Enterprise networks have become the foundation of digital business as applications, users, data and workloads are distributed across multiple physical locations and cloud environments. To meet evolving business requirements under these conditions, organizations are adopting more flexible operating models that combine automation, AI-assisted operations, cloud connectivity and experience assurance. Increasingly, they seek managed services to help them modernize legacy networking and improve security, resilience, visibility and operational agility.

“Enterprise networks have evolved from connectivity platforms into strategic business infrastructure that must adapt to changing business, application and security requirements,” said Heiko Henkes, director and principal analyst at ISG. “To remain competitive amid rapid advances in technology, organizations need network services that support AI-ready workloads while reducing operational complexity.”

ISG has distributed surveys to more than 75 enterprise managed network service providers. Working in collaboration with ISG’s global advisors, the research team will produce four quadrants representing the enterprise managed network services the typical enterprise is buying, based on ISG’s experience working with its clients. The four quadrants are:

Network Transformation Services, evaluating providers that deliver consulting-led network transformation services, helping enterprises reduce complexity, coordinate ecosystems and translate business, security, application and cloud requirements into transformation roadmaps.
Managed Network Service Evolution, assessing providers of fully managed, enterprise-grade network services that assume end-to-end responsibility for enterprise network environments through AI-assisted operations, automation, predictive analytics and operational transformation.
Network as a Service (NaaS), covering providers of cloud-native, consumption-based services that integrate networking and security through centralized management, automated provisioning and end-to-end orchestration in multicloud and multivendor environments.
Managed Enterprise Connectivity Solutions, evaluating providers delivering managed enterprise connectivity services in India with end-to-end accountability, resilient last-mile delivery, cloud connectivity and service assurance.

Geographically focused reports from the study will cover the global enterprise managed network services market and examine products and services available in the U.S., Europe and Asia Pacific. ISG analysts Kenn Walters (Europe and U.S.) and Yash Jethani Pradeep (Asia Pacific) will serve as authors of the reports.

A list of identified providers and vendors and further details on the study are available in this digital brochure. Companies not listed as enterprise managed network service providers can contact ISG and ask to be included in the study.

All 2026 ISG Provider Lens evaluations feature expanded customer experience (CX) data capturing real-world enterprise feedback on specific provider services and solutions, based on ISG’s continuous CX research.
