Unlike other firewall products that simply enhance or augment standard Linux firewall packages, the core of every Barracuda Firewall is
a specially developed application-controlled packet-forwarding firewall called the phion core. It is based on a combination of stateful
packet forwarding, TCP stream forwarding, and application-layer gateways, enhanced by custom application plug-ins that handle complex
protocols involving dynamic address or port negotiations.
The phion core technology delivers a best-of-both-worlds hybrid technology firewall that uses stateful packet forwarding as well as transparent
circuit-level application proxying, and that provides generic interfaces for content scanning, bandwidth management, and VPN tunnel selection.
