Enterprises recognize software-defined networks as essential for meeting core functionality and security requirements, ISG Provider Lens® report says

FRANKFURT, Germany--(BUSINESS WIRE)--Aug. 7, 2025-- The demand for modern, secure, cloud-enabled enterprise networks is rising among German companies as they align their digital strategies with international trends and evolving business needs, according to a new research report published today by Information Services Group (ISG) (Nasdaq: III), a global AI-centered technology research and advisory firm.

The 2025 ISG Provider Lens® Network — Software-Defined Solutions and Services report for Germany finds that German organizations are increasing their adoption of software-defined networking to improve performance, security and connectivity while minimizing operational cost. Over the past two years, system integrators and network providers have contributed to this trend by delivering flexible solutions and consumption-based managed services models that address enterprise demands. Germany’s position as one of the largest national consumers of software-defined wide area network (SD-WAN) solutions is reinforced by a strong provider ecosystem and growing requirements for standardized, scalable networking across global operations.

“SD-WANs are increasingly seen as crucial for digital advancement among German companies,” said Jon Harrod, partner and network advisory lead at ISG. “This technology enables enterprises to update their networks without the need to replace all existing hardware.”

German enterprises are simplifying operations and making networks more adaptable through the adoption of SD-WAN solutions to accelerate network transformation, the report says. These solutions enable centralized cloud-based management, automate network functions and offer real-time analytics. They also allow organizations to streamline resource management and reduce complexity, thereby avoiding frequent hardware replacements.

A major driver behind this transformation is the rapid migration to cloud and multicloud environments. Enterprises in Germany are using SDN solutions to make cloud transitions with minimal disruptions, ISG says. The technology’s ability to manage multicloud environments while ensuring comprehensive network oversight has been key to its widespread adoption. Software-defined networking also benefits companies by enabling secure data transfer across varied platforms and making it easier to deploy and optimize cloud-native technologies.

As organizations in Germany adapt to new environments, security becomes even more critical, the report says. Software-defined networking enables companies to integrate advanced security functions, such as encryption, access controls and threat detection, either alone or as part of broader secure access service edge (SASE) frameworks. Simultaneously, adoption of new technologies, including AI, generative AI and machine learning, demands flexible and adaptable network infrastructures. SDN solutions deliver these capabilities, providing superior management, real-time adaptability and automation.

“German companies that use advanced edge computing and 5G technology services benefit from the seamless and secure integration that software-defined networking offers,” said Dr. Kenn Walters, global principal lead analyst, ISG Provider Lens Research. “When these services are managed externally, organizations can do less training and fewer software upgrades, focusing instead on strategic objectives.”

The report also explores other SDN-related trends in Germany, including the increasing adoption of usage-based pricing models, particularly among small to medium enterprises, and the integration of SD-WAN within SASE in larger enterprises.
