First developed by Check Point Software in 1996 as a protocol specification for integration with anti-virusservers. Check Point first utilized its Content Vectoring Protocol (CVP) in its FireWall-1 Version 3.0 and then developed CVP into an API specification.
The CVP API defines an asynchronous interface to server applications that perform file content validation. An important feature of this is scanning files for viruses or harmful applets as they pass through firewalls. The CVP defines a client/server relationship that enables different firewall systems to share a common content validation server. In essence, the one content validation server collects from multiple firewalls the incoming files that have been flagged for inspection.
