In their own words
Colasoft Capsa
Colasoft Capsa is a Windows network analyzer for monitoring, analyzing and troubleshooting wired and wireless networks. The Enterprise edition captures packets in real time from local networks and can save transmitted data. It analyzes more than 1,800 protocols and sub-protocols, including VoIP, and displays packet details in Hex, ASCII and EBCDIC. Capsa can diagnose network problems and suggest solutions, monitor conversations, reconstruct packet streams and generate reports for selected items, the whole network or a particular network group. Its security analysis detects DoS and DDoS attacks, worm activity, ARP attacks, TCP port scans and suspicious conversations in real time. Users can set email or sound alerts and schedule capture once, daily or weekly. Capsa Free monitors up to 10 IP addresses, ends sessions after four hours and lacks WiFi connection monitoring. Professional is listed at $695, paid once for a single-seat perpetual license, one machine and one year of maintenance. Enterprise is $1,295, paid once and has a 30-day trial.
NETCAP
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.
