Deploying a NetCache appliance parallel to a firewall provides a way to off-load traffic from the firewall. Off-loading traffic from a firewall is an advantage in cases in which the firewall is slow.
The security risk with a NetCache appliance parallel to the firewall is negligible. The NetCache appliance, for example, does not contain any other software on it (for example, Telnet or RSH) that would enable an intruder to access the network. Additionally, because NetCache does not expose objects to users, intruders cannot change data.
The following illustration shows a NetCache appliance deployed parallel to a firewall.
