This chapter introduces you to the FortiBridge-1000 and FortiBridge-1000F 
products that provide fail open protection for FortiGate Antivirus Firewalls 
operating in transparent mode. Fail open protection keeps network traffic flowing 
in the event of a FortiGate unit failure. This chapter contains the following topics:

The FortiBridge products are a solution for enterprise organizations to provide fail 
open protection for FortiGate units deployed inline in transparent mode. The 
FortiBridge products use multiple probe protocols to detect failures in the 
FortiGate unit. FortiBridge zero power fail open technology means that the 
FortiBridge unit also fails open if a power failure occurs.

A FortiBridge unit functions as a pass-through device when a FortiGate unit or 
FortiGate HA cluster operating in transparent mode fails or loses power. The 
FortiBridge unit bypasses the FortiGate unit to make sure that the network can 
continue processing traffic. The FortiBridge unit is not a firewall or antivirus 
device. FortiGate services are not applied when the FortiBridge unit bypasses 
traffic.

This document describes how to install, configure and maintain the 
FortiBridge-1000 and the FortiBridge-1000F products.
