What is Npcap DLL?

Npcap, or Network Packet Capturing Library, is a dynamic-link library (DLL) designed for network packet capture and injection on Windows operating systems. It serves as an improved replacement for the WinPCAP library, offering enhanced performance, compatibility with modern hardware, and support for advanced features such as real-time packet filtering and multi-threading. Npcap operates at the kernel level to ensure low overhead and high efficiency in capturing network packets, making it a preferred choice for developers and security professionals involved in network analysis, testing, and forensic investigations.
