Fortinet FortiGate-121G Firewall

The FortiGate-121G is the onboard-storage variant of the FortiGate-120G: a 480 GB SSD dedicated to local logging and reporting, for sites that want to keep their logs without an external FortiAnalyzer. It shares the same Fortinet SP5 ASIC platform: 39 Gbps of firewall throughput, 35 Gbps of IPsec VPN and advanced threat protection through FortiGuard services powered by artificial intelligence.

Its 4 10GE SFP+ FortiLink slots integrate FortiSwitch switches as a logical extension of the firewall, while its 8 SFP slots and 16 GE RJ45 ports offer maximum flexibility for network segmentation. Management is centralized through FortiOS, FortiManager or FortiCloud.

Designed for critical infrastructures, the FortiGate-121G includes two integrated redundant AC power supplies and a dedicated TPM module for storing cryptographic keys.
