Introduction
Network Analysis Tools are specialized solutions used to inspect, capture, and analyze network traffic in order to understand performance, troubleshoot issues, and detect anomalies. Unlike basic monitoring tools, these solutions dive deeper into packet-level data, protocols, and traffic patterns to provide actionable insights into how networks behave.
With increasing adoption of cloud computing, distributed systems, and security-driven architectures, network analysis has become essential for diagnosing performance bottlenecks, identifying suspicious activity, and optimizing traffic flow. Modern environments require more than surface-level metrics—teams need granular visibility into every packet and connection.
Common Use Cases
