Managed network services are when a business hires an outside provider to design, run, monitor and fix its communications systems—like internet links, routers, security gateways and wireless access—so the company doesn’t handle day-to-day network work itself. For investors, these contracts often mean steady, ongoing revenue and lower operational risk because the provider handles uptime, security and scaling—similar to leasing a well-maintained office building rather than owning and repairing it—which can make cash flow and growth more predictable.
network as a service (naas)technical
Network as a service (NaaS) is a cloud-based offering that delivers networking capabilities—like secure connections, traffic routing and performance monitoring—on a pay-as-you-go basis instead of a company owning and running the hardware. For investors, NaaS matters because it turns a capital-heavy, specialist function into a recurring revenue service for providers and gives customers flexibility and faster scaling, which can drive predictable cash flows and faster adoption of cloud-based business models.
iottechnical
The Internet of Things (IoT) describes a network of everyday devices—such as appliances, vehicles, and equipment—that are connected to the internet and can share data automatically. For investors, IoT represents a growing trend that can drive efficiency and innovation across many industries, potentially creating new opportunities for growth and value. Its expansion influences how companies operate and compete in a digitally connected world.
edge computingtechnical
Edge computing is a technology that processes data close to where it is generated, such as sensors or devices, rather than sending it all to a distant central location. This allows for faster decision-making and reduces delays, much like having a local office handle urgent matters instead of waiting for instructions from a main headquarters. For investors, it signifies improved efficiency and real-time insights, which can enhance the performance of technology-dependent industries.
genaitechnical
Generative AI (genai) is a type of artificial intelligence designed to create new content, such as text, images, or music, that resembles human-produced work. It matters to investors because it has the potential to transform industries by automating tasks, enhancing creativity, and enabling new products and services, which can influence company performance and market opportunities.
voiptechnical
Voice over Internet Protocol (VoIP) is a technology that carries phone calls and other voice services over the internet instead of traditional telephone lines. Like switching from a landline to a streaming service for music, it can cut costs, add features and scale quickly, which matters to investors because it affects a company’s expenses, recurring revenue potential, growth prospects and exposure to network reliability or cybersecurity risks.
vpntechnical
A VPN (virtual private network) creates a secure, private “tunnel” through the public internet that hides a device’s location and encrypts the data sent and received, like sealing a letter inside a locked envelope while it travels through the mail. For investors, VPNs matter because they reduce the risk of data breaches, support remote work and regulatory compliance, and represent a recurring-revenue market driver for companies that sell cybersecurity and networking services.

Organizations transition from in-house ownership as networks grow more complex and regulated across distributed enterprise environments, ISG Provider Lens® report says
LONDON--(BUSINESS WIRE)--
Enterprises in Europe are changing how networks are designed, operated and governed using managed network services (MNS) that increasingly incorporate AI-assisted and AI-driven capabilities, 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 Europe finds that many organizations across the region historically resisted MNS, relying instead on large internal IT and data operations teams. Companies retained direct control of mission-critical infrastructures, including private data centers, wide area networks and on-premises networking resources. Early MNS offerings were limited in scope, focusing mainly on wired connectivity and basic maintenance. However, as European enterprise networks expanded and diversified, MNS solutions evolved to support multiple delivery models that address the demands of hybrid architectures and global operations.
“In an increasingly threat-heavy environment, enterprises must maintain strong security, minimize downtime and meet multiple regulatory requirements while supporting mobile and cloud-centric workforces,” said Jon Harrod, partner at ISG. “MNS solutions have become central to addressing these operational and security demands across European enterprise environments.”
Hybrid work and distributed operations have become standard in enterprises across the region, increasing complexity for IT and network teams, the report says. Employees now need secure and reliable access to applications from virtually anywhere, while networks must support legacy systems alongside cloud workloads, IoT devices and edge platforms. Simultaneously, rapid advances in AI-powered infrastructure and more persistent cyber threats are raising expectations for continuous monitoring and rapid security responses. Together, these factors are leading enterprises to rely more on MNS to oversee complex environments.
Alongside broader adoption of MNS, European enterprises are increasingly turning to network as a service (NaaS) solutions rather than building and operating complex network environments internally, ISG says. They seek providers with advanced expertise, automation capabilities and specialized staffing. AI and GenAI tools enable network operators to automate routine tasks, improve predictive analytics and strengthen incident detection and response. Enterprises are prioritizing NaaS providers with these capabilities to reduce operational burdens and enable more efficient, scalable and secure services.
Across Europe, network services are also helping enterprises meet regulatory and data sovereignty requirements while adapting quickly to changing business needs, such as scaling up operations during expansion phases. By delegating resource-intensive network operations, enterprises can focus on core business priorities while improving efficiency and sustainability.
“Organizations are increasingly aligning network strategies with sustainability and energy efficiency goals,” said Kenn Walters, lead author of the report. “MNS offerings support these objectives by optimizing network resources, helping organizations reduce their carbon footprint.”
The report also explores other trends in the enterprise MNS market in Europe, including IoT and edge computing adoption and efforts to balance modernization with cost control amid faster refresh cycles.

The 2025 ISG Provider Lens® Enterprise Managed Network Services report for Europe evaluates the capabilities of 36 providers across three quadrants: Managed Network Services Evolution, Managed Enterprise Connectivity Solutions (DIA, VoIP & VPN) and Network as a Service (NaaS).
The report names Accenture, Colt, Deutsche Telekom, GTT, NTT DATA and Orange Business as Leaders in all three quadrants. Comcast Business, HCLTech, Verizon Business and Wipro are named as Leaders in two quadrants each, while Capgemini, Computacenter, DXC Technology and Kyndryl are named as Leaders in one quadrant each.
In addition, Computacenter and DXC Technology 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 MNS 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.
