Insights from the SPARK Matrix™: Network Observability – Q3 2025 Report

There is more complexity in today’s network environments than ever before. This multivendor, hybrid/multicloud infrastructure, with applications hosted in private data centers, software-as-a-service (SaaS) and unified-communications-as-a-service (UCaaS) providers’ systems, and public cloud, all inter-connected by a variety of WAN technologies, has made efforts focused on performance management, security, and artificial intelligence (AI) very complicated.

Network observability solutions combined with best practices is the answer. By providing deep insights into network traffic and application performance, these tools help IT teams quickly pinpoint issues and restore smooth operations.

NETSCOUT, for instance, leverages deep packet inspection (DPI) technology within its network observability solutions. DPI provides granular visibility into network traffic, enabling IT to identify the root cause of problems, whether it’s a specific application, user, or device, even within complex hybrid environments. Additionally, NETSCOUT observability solutions provide continuous synthetic testing capabilities integrated into the NETSCOUT nGeniusONE solution to reduce the time needed to identify emerging issues, even when users are inactive. This approach delivers consistent visibility across the edge, data center, and colocation environments. Together, these capabilities help accelerate resolution times and reduce disruptions to critical business operations.
