ISG to Publish Report Assessing SDN Providers

Upcoming ISG Provider Lens™ report will evaluate providers of several SDN-related solutions and services, including managed SD-WAN and SDN consulting

Information Services Group (ISG) (Nasdaq: III), a leading global technology research and advisory firm, has launched a research study examining the way providers deliver enterprise network services, including software-defined networking (SDN).

The study results will be published in a comprehensive ISG Provider Lens™ report, called Network – Software Defined Solutions and Services, scheduled to be released in June 2023. The report will cover providers with offerings including software-defined wide area networks (SD-WAN), managed SD-WAN services, implementation support, and networking-related consulting and advisory services.

Enterprise buyers will be able to use information from the report to evaluate their current vendor relationships, potential new engagements and available offerings, while ISG advisors use the information to recommend providers to the firm’s buy-side clients.

The study looks at edge technologies and services, such as IoT, universal/virtual customer premises equipment (u/vCPE) and software-defined local area networks (SD-LANs), including those delivered through mobile and 4G/5G technologies. It also examines secure access service edge (SASE), which is an overarching, secure and fully integrated network environment for businesses.

“The study will look at ways that providers of SDN and related services can help enterprises better and more securely manage their networks, offer new network functionality, and in many cases, contain network costs,” said Jan Erik Aase, partner and global leader, ISG Provider Lens Research.

ISG has distributed surveys to 90 providers of SDN-related services. Working in collaboration with ISG’s global advisors, the research team will produce five quadrants representing the typical SDN-related services enterprises are buying, based on ISG’s experience working with its clients. The five quadrants are:

  • Managed SD-WAN, evaluating providers of enterprise SD-WAN that deliver managed solutions and services. Included are associated services such as identity and access management, provided as wrap-around services directed toward streamlining enterprises’ network operations.
  • SDN Transformation Services (Consulting and Implementation), assessing providers of services associated with delivering software-defined networking and SD-WAN solutions to enterprises, from initial consulting to service delivery and rollout.
  • Enterprise Networks Technology and Service Suppliers, covering providers of software-defined networking from core to edge technology and services, purchased by either service providers for specific projects or enterprises for their operations or for equipment delivery. This includes SD-WAN implementations or partial implementations.
  • Edge Technologies and Services, evaluating vendors of technologies, across hardware and software, management and reporting tools, and applications and services, associated with edge network technology for enterprises. Edge technologies, services and computing are used frequently in IoT and industrial IoT networks.
  • SASE (Secure Access Service Edge) Solutions and Services, assessing providers of SASE solutions offered to enterprises as overarching integrated networks and security solutions from the enterprise core to the edge. These include solutions moving into pilots and solutions commercially deployed into production.

Geographically focused reports from the study will cover the global SDN market and examine products and services available in the U.S., the U.K. and Germany. ISG analysts Avimanyu Basu, Kenn Walters and Varsha Sengar will serve as authors of the reports.

A list of identified providers and vendors and further details on the study are available in this digital brochure. Companies not listed as SDN providers can contact ISG and ask to be included in the study.
