SocketBlock is a high performance ActiveX/COM packet filtering component that allows network applications to have the ability to filter packets from other applications attempting to connect or send to or from the machine using SocketBlock.

This type of packet filtering ability is extremely important if a network application is to be able to deal with malicious [network] attacks such as Denial Of Service attacks. By trapping the packets that meet user defined rules at the driver level before the application receives them, SocketBlock can provide an application with the ultimate in security while using minimal resources.
