This solution brief explains how Profitap and Security Onion enable continuous threat monitoring and investigation across high-speed networks. Profitap TAPs provide fail-safe, non-intrusive access to North-South and East-West traffic, while Network Packet Brokers centralize, filter, deduplicate, timestamp, slice, and load-balance data before it reaches monitoring sensors. Security Onion combines full packet capture, network and host intrusion detection, Zeek metadata, system logs, and powerful threat-hunting tools within a unified interface. Analysts can move from alerts and metadata directly to packet-level evidence for deeper investigations. The joint architecture lowers unnecessary bandwidth consumption, ensures monitoring tools receive actionable traffic, and supports real-time detecti
