F1000-E
Deployed at the egress of an enterprise network, F1000-E firewalls can protect against external attacks, ensure security access from the external network to the internal network resources (such as servers in the DMZ zone) through NAT and VPN functions, and control access to the internal network by using security zones. You can deploy two firewalls in the network for redundancy backup to avoid a single point failure.
