For 14 years, WinPcap was the standard libpcap package for Windows. But when
Windows 10 was released without NDIS 5 support, WinPcap failed to keep up,
leaving users wondering what to do. Fortunately, the Nmap Project stepped up
and converted the original WinPcap to the new NDIS 6 API, giving users a fast
and completely compatible alternative to WinPcap for Windows 10.
Windows 10 1607 also introduced strict driver-signing requirements that WinPcap
can't meet. Npcap is fully compliant, with its drivers tested and co-signed by
Built on the tried-and-true WinPcap codebase, with a host of exciting new
features, and extensively tested with currently-supported versions of Windows,
Npcap is the future of WinPcap. Ready to give Npcap a try? Just download the latest installer. Npcap works great
with Wireshark, Nmap, and more of your favorite tools already. For software
that's written with WinPcap in mind, simply select "WinPcap API-compatible
mode" at installation.
