Notable IT networking aspects: SDN and VPNSoftware Defined Networking (SDN) and Virtual Private Networks are important technologies less bound by specific IT networking hardware, relying instead on software transmissions of data. SDN helps operators design, build, and maintain their networks efficiently while VPNs securely extend private networks across public networks in order to enable users to share data across those networks. In 2022, the SDN market was valued at 26 billion U.S. dollars and was forecast to double its value by 2027. The global VPN market, on the other hand, is considerably larger, being worth 44.6 billion U.S. dollars in 2022. In this market, growth is partially driven by enterprises using this technology to enable their employees to access company resources from different locations.
Network Security InfrastructureNetwork security infrastructure is the process of protecting a network infrastructure by installing security measures in order to deny unauthorized access, and to prevent the access, modification, and theft of resources and data. The main segments of Network Infrastructure Security are access control, application security, firewalls, VPNs, behavioral analytics and wireless security.
Network Security Infrastructure requires a holistic approach and is usually applied to enterprise IT environments. In 2022, spending on network security equipment exceeded 19 billion U.S. dollars, while security spending in the infrastructure protection segment totaled 27.4 billion U.S. dollars.
Companies and IT networking servicesIn terms of services, SolarWinds was the most important network management technology, accounting for a market share of 12.5 percent in 2022. The centralization of critical network services is an essential component of the management and functionality of global networks. Network infrastructure technologies such as DNS, DHCP, and IPAM (together known as DDI) all play an essential role in this process, with vendors including Microsoft, Cisco Systems, and Infoblox providing solutions in this space. Additionally, Cisco was also the leading enterprise network infrastructure vendor in 2022, with a market share of 41 percent.
In the case of network security, the global corporate web security market revenue is expected to surpass five billion U.S. dollars by 2022. Endpoint security sales are also forecast to increase to nearly 11.2 billion U.S. dollars by 2022.
