WinPcap
Business Profile
Core Value Proposition
WinPcap provides a Windows packet capture library and driver that enables applications to capture and transmit network packets at the low level, with kernel-level filtering, a network statistics engine, and a Windows version of the libpcap API.
Target Customer
Developers building network analysis and packet-capture tools for Windows; IT professionals needing low-level access to Windows network traffic; open-source and commercial network tool vendors (e.g., those integrating with Wireshark, Nmap, Snort, ntop).
Key Differentiator
An industry-standard Windows packet capture library consisting of both a driver and a library, with the Windows version of the libpcap API, historically used as the capture engine behind major tools like Wireshark, Nmap, Snort, and ntop.
Implementation Timeline
Last released as version 4.1.3 in 2018; development has ceased, with no roadmap for future updates. Riverbed staff oversight and bug-reporting are no longer available; Npcap is recommended as a replacement.
Pain Points
- 1Provides low-level Windows access to network packets, bypassing the protocol stack.
- 2Offers a Windows-compatible API (libpcap) to enable cross-tool development and integration.
- 3Establishes a widely adopted capture engine used by multiple open-source and commercial network tools.
Key Features
- 1Driver + library enabling low-level Windows network access
- 2Kernel-level packet filtering
- 3Network statistics engine
- 4Support for remote packet capture
- 5Windows version of the libpcap Unix API
Target Customer Industries
Client Results
