The "secure-from-the-ground-up" design principles of your Amaranten Firewall result in high reliability and uptime. However,
in any complex system, there is always a risk for failures. These may range from manual errors to more complicated
hardware component errors. Whatever the cause, communication disruptions are, at the very least, annoying. We consider
them totally unacceptable.

The high availability feature of Amaranten Firewall enables you to setup a secondary, redundant back up firewall system,
thereby minimizing the risk of communication disruptions.

Upon any failure on the primary firewall, the secondary firewall automatically takes control over the data flow to guarantee
network uptime. The transition takes only a fraction of a second and is totally invisible to all traffic.

A dedicated ethernet interface is used for synchronization, which guarantees that all state information, including VPN
sessions, are synchronized without delays, even in solutions with extremely high throughput.

Moreover, our solution permits the redundant units to be synchronized using fiber optic links and can thereby be installed
in completely separate locations.

The Amaranten Firewall Manager automatically makes sure that both the redundant back up unit and the primary unit share
the same configuration, meaning that only the primary firewall needs to be configured.
