This market covers data center network switches and the requisite management and automation platforms for them. Data center switches are Ethernet switches installed in a data center environment intended to provide connectivity for endpoints, including servers, firewalls, and Layer 4 through Layer 7 appliances and mainframes. Data center switches provide foundational connectivity mostly for compute resources in the data center. This is required to enable applications in support of business requirements. Emerging use cases that drive investments on data center networks include both AI and edge compute workloads.
The data center and cloud networking vendors covered in this market provide hardware and/or software solutions to deliver connectivity primarily within enterprise data centers. This includes data center core/spine switches, access switches (top of rack [ToR], leaf), virtual switching, Ethernet fabrics, network operating systems (NOSs) and network overlays, and the requisite management, automation and orchestration of those components.
Enterprise Networking and Communications refers to the products and services that enable secure, scalable, and high-performance connectivity and communication across distributed enterprise environments. This category includes markets that focus on core and edge networking, unified communications, private and public mobile networks, and managed network services—supporting digital transformation, and operational efficiency.
Gartner defines the enterprise wired and wireless LAN market as the infrastructure that enables secure connectivity across enterprise locations. This encompasses the hardware, software, and management capabilities required to deliver physical and logical network connectivity, enforce zero-trust security principles, and automate operations across campus, branch, and remote environments, including operational technology (OT) domains. Enterprise wired and wireless LAN infrastructures solve the operational complexity of delivering secure, scalable connectivity across distributed enterprise environments. As organizations expand across campus, branch, remote, and operational technology domains, traditional network deployment and management approaches become too resource-intensive and inconsistent to meet business demands. The offered capabilities address the business problem of fragmented network operations by unifying life cycle management (that is, provisioning, monitoring, policy enforcement, and incident response) into a single, software-driven system. This reduces manual effort, shortens resolution times, and improves compliance with governance and security requirements. While hardware remains foundational, it is the infrastructure operations software (that is, automation, telemetry, and policy orchestration) that delivers the operational and business value enterprises seek. Tangible outcomes include faster site turn-up, proactive issue detection and remediation, consistent user experience, and alignment of network operations with enterprise workflows through IT service management (ITSM) integration. Organizations also gain flexibility through cloud, on-premises, hybrid, and network as a service (NaaS) consumption models, enabling them to scale operations efficiently while maintaining control over data and performance.
Gartner defines network access control (NAC) as technologies that enable organizations to implement policies for controlling access to corporate infrastructure by both user-oriented devices and Internet of Things (IoT) devices. Policies may be based on authentication, endpoint configuration (posture) or users' role/identity. NAC can also implement postconnect policies based on integration with other security products. For example, NAC could enforce a policy to contain the endpoint based on an alert from a SIEM. An organization should evaluate the following capabilities: • Device visibility/profiling • Access control • Security posture check • Guest management • Bidirectional integration with other security products.
Gartner defines software-defined WAN (SD-WAN) as products used to connect branch locations to other enterprise and cloud locations. SD-WAN products provide dynamic path selection based on business or application policy, routing, centralized orchestration of policy and management of appliances, virtual private network (VPN) and zero-touch configuration. SD-WAN products are WAN transport/carrier-agnostic and create secure paths across physical WAN connections.
