New ISG research says companies should integrate different forms of NaaS for automation, efficiency and risk management
STAMFORD, Conn.: #AI--Most enterprises are exploring or adopting network as a service (NaaS) to support AI initiatives, simplify network management and reduce costs, but a new research report from global AI-centered technology research and advisory firm Information Services Group (ISG) (Nasdaq: III), finds many may fail to capture its full value because they do not understand the range of NaaS options available.
The ISG Market Lens™ 2026 Network as a Service Report, published today, draws on survey data and adoption patterns observed in ISG advisory engagements that show NaaS is becoming a common part of enterprise IT modernization initiatives. A survey conducted in April 2026, covering primarily large enterprises in the Americas and Europe, found that 60 percent had either broadly or partially adopted NaaS and 31 percent were conducting pilots or evaluations. Cloud migration, increasing use of SaaS and internal mandates for digital transformation were common reasons for NaaS adoption.
While organizations have traditionally purchased wide-area connectivity as a carrier service, NaaS allows them to also consume functions such as network provisioning and management as part of a bundle of services. ISG’s survey shows most enterprises see NaaS as a fundamental architectural shift that is the future of networking, but do not fully understand the differences among NaaS offerings from hyperscalers and network transport providers and how they target different parts of the enterprise technology stack.
“Carrier NaaS transport providers can help enterprises avoid vendor lock-in, enable workload migrations and provide connectivity at the edge, while hyperscaler and cloud providers can provide the infrastructure for the apps and AI workloads,” said Leon Platts, partner and president, ISG Network and Software. “To maximize the value of NaaS and minimize risk, companies should explore an integrated approach.”
Hyperscalers, traditionally the dominant providers of NaaS, offer it in conjunction with cloud hosting of workloads. This allows organizations to avoid capital expenses but can lead to vendor lock-in if they rely solely on the cloud provider for NaaS. Carriers, which specialize in connecting workloads, offer NaaS that can automatically reconfigure networks to optimize for factors such as cost, bandwidth or latency, preventing clients from being locked into a particular provider’s infrastructure.
Most respondents to the survey prefer to share control and co-management of the network in close cooperation with NaaS providers. Nearly 90 percent have moderate to high confidence in network operations automation with some human oversight. Just over half were open to eventually taking over more control of the network from the provider as long as risks were well managed.
Operational staff tend to view NaaS as an inevitable evolution and a likely boon to agility and flexibility, but many business leaders are skeptical, the research shows. Though 18 percent of C-level executives are excited about opportunities with NaaS, 42 percent are interested but mostly unconvinced. Enterprises are most likely to adopt NaaS for greenfield sites, business expansion and SaaS and other cloud-based workloads, with large majorities considering those use cases suitable for NaaS. Fewer are comfortable with trusting highly regulated environments such as legal and healthcare to such services.
Enterprises see integration complexity, security and cost uncertainty as the biggest challenges in the transition to NaaS. They want providers to deliver better customer support, more flexible contracts with transparent pricing and higher reliability through features such as AI-driven predictive operations.
“NaaS is becoming part of the modernization portfolio of enterprises pursuing cloud-first, AI-driven operations,” said Alex Bakker, ISG distinguished analyst and co-author of the report. “While companies see it as a strategic enabler of growth, they expect simpler migration, proven security and clear long-term costs as they continue to expand NaaS adoption.”
