Fortinet FortiGate 100E — End-of-Life & EOSL Dates
The FortiGate 100E is a one-rack-unit next-generation firewall for mid-sized enterprise campus and branch edges, built on Fortinet's SoC3 security processor. The series is rated at 7.4 Gbps of firewall throughput with 2 million concurrent sessions, 4 Gbps of IPsec VPN, 500 Mbps of IPS and 250 Mbps of full threat protection.
The 100E model carries 20 Gigabit RJ45 ports plus two shared RJ45/SFP media pairs; the 101E variant adds a 480 GB SSD and the 100EF swaps the copper switch ports for fiber. It manages up to 64 FortiAPs, runs 10 virtual domains, and supports active-active or active-passive HA clustering with an optional external redundant power supply.

Options from here
1 Fortinet FortiGate 100E part number is past Fortinet end of service while 2 remain supported (to Jan 2028). For the past-EOSL units, these are the usual paths:
Keep it in production past the OEM cutoff with an independent maintainer.
Buy spares now, while units still circulate on the secondary market.
It is unsupported today. Set a migration timeline and budget.
Low-criticality role: document the risk, harden backups, retire on your terms.
Independent and informational. EOSL.ai sells no hardware and no maintenance, and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the role the asset plays.
