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.
IT Security refers to products and services that protect digital systems and data from cyber threats and unauthorized access. This category includes markets that focus on network security, identity management, data protection, and cloud security, enabling organizations to reduce risk, ensure compliance, and operate securely in a digital world.
Infrastructure monitoring tools capture the health and resource utilization of IT infrastructure components wherever they reside (e.g., in a data center, at the edge, or IaaS or PaaS in the cloud). This enables I&O teams to monitor the availability and resource utilization data of physical, virtual, software entities, and AI systems — including servers, containers, network devices, database instances, hypervisors, storage, and basic application monitoring. These tools collect data in near real time and perform historical data analysis or trending of the elements they monitor.
The network intrusion detection and prevention system (IDPS) appliance market is composed of stand-alone physical and virtual appliances that inspect defined network traffic either on-premises or in the cloud. They are often located in the network to inspect traffic that has passed through perimeter security devices, such as firewalls, secure Web gateways and secure email gateways. IDPS devices are deployed in-line and perform full-stream reassembly of network traffic. They provide detection via several methods — for example, signatures, protocol anomaly detection, behavioral monitoring or heuristics, advanced threat defense (ATD) integration, and threat intelligence (TI). When deployed in-line, IDPSs can also use various techniques to detect and block attacks that are identified with high confidence; this is one of the primary benefits of this technology. Next-generation IDPSs have evolved in response to advanced targeted threats that can evade first-generation IDPSs. (Retired as of Mar-12-2026).
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.
Server virtualization includes a range of technologies that abstract an underlying infrastructure layer (networking, storage and compute [including memory]). In doing so, it improves hardware utilization, workload portability, automation and availability. Server virtualization is most often associated with hypervisor-based server workloads running in data center environments on industry-standard servers. In reality, server virtualization incorporates multiple technologies, spans locations from public cloud to edge, and supports initiatives for both cloud-native transformation and infrastructure modernization. It includes hardware-, cloud- and software-based technologies.
