NetFlow vs Metadata vs Packet Inspection: What Are the Differences?
This white paper compares three approaches to network monitoring: deep packet inspection, NetFlow, and metadata analysis. Packet inspection provides the most complete view, including headers, payloads, timing, latency, and server response details, but produces large data volumes and requires skilled analysis. NetFlow summarizes conversations for long-term monitoring, bandwidth analysis, intrusion detection, and identifying top talkers, but lacks payload and packet-level timing information. Metadata offers a balance by converting packet data into searchable statistics covering retransmissions, application response, DNS activity, and performance trends. The paper explains how IOTA combines packet capture, flow-style simplicity, long-term metadata, dashboards, encrypted storage, and exportabl
