Microolap TCPDUMP for Windows® 4.9.2 build 1135.27

Command-line sniffer (packet capture tool) for Windows®

TCPDUMP for Windows® is a clone of TCPDUMP, the most used network sniffer/analyzer for UNIX, compiled with the original tcpdump code (, and Microolap Packet Sniffer SDK (no libpcap/WinPcap/npcap).

TCPDUMP for Windows® uses almost the same stack of network traffic capture technologies as EtherSensor, the network traffic analysis platform that helps our customers solve many Security Operation Center tasks in combination with DLP, SIEM, U(E)BA, eDiscovery, Enterprise Archiving, and DAG systems.
