How can NetFlow help expose bandwidth abuse on internal networks?

Example Concept: NetFlow captures detailed information about network traffic, including source and destination IP addresses, ports, protocols, and the amount of data transferred. This data helps in identifying bandwidth abuse by highlighting top talkers, unusual traffic spikes, and anomalous patterns that deviate from normal network behavior. By correlating this information with known network policies and expected usage patterns, administrators can take corrective actions such as adjusting QoS policies, implementing rate limiting, or investigating potential security incidents.
