The competitive distribution of the global Network Transformation Market Share is a landscape dominated by a handful of major, incumbent networking and software vendors who have successfully navigated the shift from hardware-centric to software-defined networking. Market share in this industry is a reflection of a vendor's ability to provide a comprehensive and integrated portfolio of solutions spanning Software-Defined Networking (SDN), Network Function Virtualization (NFV), and, most importantly, the high-growth Software-Defined WAN (SD-WAN) segment. The leaders have established their positions through a combination of in-house R&D, strategic acquisitions of innovative startups, and by leveraging their massive installed base and global sales channels. The battle for market share is a high-stakes competition to become the strategic platform provider for the next generation of enterprise and telecommunications networks, a position that promises years of recurring software and services revenue.

Cisco Systems holds a commanding and dominant market share across the entire network transformation landscape. As the long-standing global leader in enterprise networking hardware (routers and switches), Cisco has a massive incumbency advantage. The company has successfully pivoted its business model by developing a comprehensive software portfolio. In the SD-WAN market, it holds a leading position through its dual-platform strategy: its acquisition of Viptela provided it with a powerful, enterprise-grade SD-WAN solution for large, complex deployments, while its Meraki platform offers a simple, cloud-managed, all-in-one networking and security solution that is hugely popular in the mid-market and for distributed enterprises. In the data center, its Application Centric Infrastructure (ACI) is a leading SDN platform. By offering a complete and integrated portfolio that spans from the data center to the WAN and the branch, and by leveraging its unparalleled brand recognition and customer base, Cisco has maintained its position as the overall market share leader.

While Cisco is the giant, the market is not a monopoly. A number of other major vendors hold a significant market share and are competing fiercely. VMware, through its acquisition of VeloCloud, has become a major leader in the SD-WAN market. Its VeloCloud platform is renowned for its excellent application performance and its ability to provide reliable connectivity over standard broadband internet connections. VMware's strength lies in its dominant position in enterprise server virtualization, which it is leveraging to push its vision of a complete "Virtual Cloud Network" that extends from the data center to the edge. Another major player is Fortinet. Fortinet has a unique and highly successful strategy of converging networking and security. It has built its significant market share by offering a "Secure SD-WAN" solution that integrates the SD-WAN functionality directly into its market-leading Next-Generation Firewall (NGFW) appliances. This integrated security and networking approach is very appealing to security-conscious organizations and has allowed Fortinet to rapidly gain share.

The competitive landscape also includes other major networking and technology vendors who hold important positions. HPE Aruba has a strong and growing share, particularly with its comprehensive edge-to-cloud networking portfolio that includes strong SD-WAN and security capabilities. Juniper Networks is a key competitor, particularly in the service provider and large enterprise data center markets, with a strong portfolio of SDN and automated networking solutions. In the telecommunications NFV space, the major network equipment providers like Ericsson and Nokia are the dominant players for the virtualization of the mobile core network. The market share dynamic is therefore a complex battle between the networking incumbents, the virtualization software giants, and the security-focused vendors, all of whom are racing to offer the most complete and integrated platform for the software-defined, cloud-first era.
