This driver filters all network driver at the lowest level (before the data is transferred to the network card). The driver monitors all kind of network protocols possible - Ethernet, IP, TCP, UDP. Thought, it is possible to implement custom router, firewall, sniffer, anti-virus or whatever solution needed. The driver is written using Windows Driver Development kit and NDIS technology. Installs as Network Miniport driver. Has an API for external access using DLL.
We can build any kind of kernel-mode and user-mode solutions that involve Windows drivers. We can build both for 32 bit and 64 bit platforms and sign the drivers using digital signature.
