Content Vectoring Protocol

What is Content Vectoring Protocol?
Content Vectoring Protocol (CVP) is a protocol specification used to filter data passing through a firewall in anti-virus servers. CVP is used to scan data moving out of a firewall into an external scanning device.

CVP scans files for viruses or other malware when they pass a fire well. It also creates a client-server relationship where different firewalls use the same content validation server. This allows a content review server to catch incoming files from multiple firewalls if they have been flagged as suspicious.

CVP simplifies the use of anti-virus software and content blocking products with firewalls.

The Content Vectoring Protocol was first developed in 1996 by a company called Check Point Software to enable antivirus solutions to communicate with antivirus servers. The first implementation of CVP was on Firewall-1 version 3.0, but CVP was later developed as an application programming interface (API) specification.

A typical use of CVP would be to move all incoming SMTP messages to a content review server, which would search the data for malicious Active-X code. CVP is primarily used in virus scanning of data from sources such as email messages or downloaded Internet files as it traverses a firewall.

There are a number of providers who support CVP.
