The global deployment of 5G networks, including private 5G solutions for enterprises, has significantly increased the need for emulators capable of testing high-speed, low-latency applications in real-world conditions. Simultaneously, the widespread adoption of SD-WAN and multi-cloud environments requires robust network validation tools to ensure application performance and reliability. The growing complexity of IoT ecosystems and edge computing further amplifies the demand for emulators that can simulate constrained, variable, and unpredictable network scenarios. In addition, rising cybersecurity concerns are prompting organizations to use emulators to test network resilience and security infrastructure against attack simulations.
