NETCAP vs NetworkMiner

NETCAP converts network packet streams into structured audit records for network analysis, security research, machine learning and forensics. Its free Core edition covers 66+ record types for protocols including TCP, UDP, HTTP, TLS, DNS and DHCP. Core captures live 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 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 Pro analyzes captures locally without an upload step. Pro is available for macOS, Windows and Linux and includes email support. The plan is listed at $548 a month, with a €48/year option also shown, and a 14-day trial without a credit card. Enterprise has custom pricing and includes unlimited team seats, priority support with an SLA, custom integrations and volume licensing.

NetworkMiner analyzes captured network traffic and can sniff live traffic, extracting artifacts such as files, images, emails, and passwords from PCAP files. It also builds a host inventory from IP address information for passive asset discovery and communication overviews. The free edition supports live sniffing and PCAP and ETL parsing on Windows and Linux, but not PcapNG parsing. Professional accepts PcapNG, Pcap-over-IP, and PacketCache data in addition to PCAP, ETL, and live sniffing, and exports results to CSV, JSON-LD, and XML. Its protocol features include file extraction across listed protocols, while VoIP support includes audio extraction from unencrypted calls. Professional also provides OSINT lookups for hashes, IP addresses, domains, and URLs. NetworkMiner does not decrypt HTTPS or other TLS-encrypted sessions. Extracted data stays on the end-user device rather than in the cloud. The source code is GPLv2 free and open source. Netresec warns that opening PCAPs can automatically extract malware and recommends Linux or Windows Sandbox to reduce self-infection risk.
