FortiGate 400E-BYPASS Firewall
FortiGate 400E-BYPASS is a specialised next-generation firewall appliance with bypass interface support, designed to provide high-performance security and reliability for enterprise networks, branch offices, and campus deployments requiring resilient fail-open connectivity in the event of power or system failure.
Overview:
The FortiGate 400E-BYPASS combines standard NGFW features — such as firewalling, intrusion prevention, Secure SD-WAN and VPN — with a robust bypass architecture that allows traffic to continue flowing even if the firewall is offline or rebooting. This makes it especially useful in environments where network uptime and deterministic connectivity are critical.
With 32 × RJ45 bypass port pairs and separate management and HA interfaces, this appliance delivers flexible connectivity for large enterprise perimeters, regional hubs, and environments requiring high-availability security infrastructure.
