Upcoming ISG Provider Lens™ reports will cover providers transforming enterprise networks into intelligent, software-defined platforms

Information Services Group (ISG) (Nasdaq: III), a global AI-centered technology research and advisory firm, has launched a research study of managed network service providers and network operators, exploring how they enable enterprises to transform networks from static infrastructure assets into dynamic platforms.

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 2025. The reports will cover companies offering managed network services (MNS), managed connectivity solutions and network-as-a-service (NaaS) solutions.

Enterprise buyers will be able to use information from the reports to evaluate their current vendor relationships, potential new engagements and available offerings, while ISG advisors use the information to recommend providers to the firm’s buy-side clients.

As enterprises implement hybrid work modes and distribute applications, the role of MNS is evolving to support dynamic business operations. Modern MNS portfolios address critical enterprise concerns related to network flexibility, performance, visibility and compliance. Enterprises are increasingly adopting important new network technologies, including zero-trust security architectures, open API-based orchestration, sovereign cloud integration and post-quantum encryption support.

“Enterprises recognize how advanced technologies modernize their network infrastructure and services,” said Heiko Henkes, director, ISG Provider Lens Research. “To support modernization initiatives, providers need to enable seamless integration with existing enterprise networks using standardized interfaces and intelligent automation tools.”

ISG has distributed surveys to nearly 200 enterprise MNS providers. Working in collaboration with ISG’s global advisors, the research team will produce three quadrants representing managed network services commonly adopted by enterprises, based on ISG’s experience working with its clients. The three quadrants are:

• Managed Network Services Evolution, evaluating providers delivering comprehensive, enterprise-grade network services under long-term outsourcing agreements. Providers are assessed on their ability to integrate advanced technologies such as automation, AI-driven operations and zero-trust enforcement.
• Managed Enterprise Connectivity Solutions (DIA, VoIP and VPN), assessing providers offering fully managed connectivity solutions such as dedicated internet access (DIA), voice over internet protocol (VoIP) and virtual private networks (VPNs). They need to deliver end-to-end lifecycle services, adhere to service level agreements (SLAs) for performance and security and support modern cryptography standards.
• Network as a Service (NaaS), covering providers delivering cloud-based, on-demand connectivity and network functions that eliminate the need for in-house infrastructure. Providers are evaluated on their ability to align with Metro Ethernet Forum (MEF) principles to ensure interoperability and service quality and their capacity to offer scalable, centrally managed solutions embedded with sustainability features.

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 (U.S. and Europe) 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 2025 ISG Provider Lens™ evaluations feature expanded customer experience (CX) data that measures actual enterprise experience with specific provider services and solutions, based on ISG’s continuous CX research. Enterprise customers wishing to share their experience about a specific provider or vendor are encouraged to complete this online survey. Participants will receive a copy of this report in return for their feedback.
