Summary

NETCAP converts network packet streams into structured audit records for network analysis, security research, machine learning and forensics. Its free Core edition provides 66+ record types covering protocols such as TCP, UDP, HTTP, TLS, DNS and DHCP. Core captures live network traffic, processes PCAP files, supports distributed collection and HTTP proxy capture, and outputs Protocol Buffers, CSV, JSON streams and Prometheus metrics. It is an open-source CLI under GPL-3.0, with community support, platform binaries and Docker images. Pro adds interactive graph analysis, a network activity timeline, investigation notes and more than 35 analysis modules. It can flag anomalies in decoded traffic and draft incident reports for editing; the maker says captures are analyzed locally without an upload step. Pro is available for macOS, Windows and Linux and includes email support. Enterprise has custom pricing, unlimited team seats, priority support with an SLA, custom integrations and volume licensing. Core includes a Maltego transformation plugin, while Pro lists connections with Wireshark, Metasploit, hashcat, John and BetterCrack. The maker advertises a 14-day Pro trial without requiring a credit card.
