fortinet FortiGate 100D
The Fortinet FortiGate 100D is a 1U rack-mount enterprise firewall that anchored mid-sized corporate perimeters for years. Featuring twenty-two Gigabit Ethernet ports (including two shared SFP ports), the 100D delivered 2.5 Gbps of firewall throughput and 450 Mbps of IPsec VPN throughput. While officially at end-of-support status, the 100D remains heavily traded in secondary utility channels, educational environments, and testing labs for low-cost perimeter management.
