FortiGate 100E end of life: end of support dates
By Nico De Muynck · Updated July 26, 2026
Support ends soon, 22 days left.
The Fortinet FortiGate 100E reaches its End of Support on August 17, 2026. That is the hard stop: after it there are no firmware updates, no FortiGuard signatures, no hardware replacement and no technical support.
FortiGate 100E lifecycle milestones
These dates are from Fortinet's Product Life Cycle listing for the FG-100E hardware.
| Milestone | Date |
|---|---|
| End of Order (last order date) | 2021-08-17 |
| Last Service Extension Date | 2025-08-17 |
| End of Support | 2026-08-17 |
What these dates mean
End of Order is the last day the FortiGate 100E could be purchased new from Fortinet. Last Service Extension Date is the last day you could buy or extend a FortiCare support contract for it. End of Support is the one that matters most: after it the device stops receiving firmware updates and FortiGuard security signatures, so every new vulnerability stays unpatched and the firewall becomes a standing security and compliance risk. A firewall running without current FortiGuard updates is especially exposed, because it sits at the network edge. For how Fortinet's lifecycle works in full, see the Fortinet EOL guide.
What replaces the FortiGate 100E?
Fortinet positions the FortiGate 100F as the successor to the 100E, with higher-throughput options such as the FortiGate 120G in the current generation. Moving up also gets you a FortiOS release that stays supported for years rather than months. If you are still running a 100E at the edge, plan the swap before End of Support rather than after: renewing FortiCare is no longer possible past the Last Service Extension Date. New to the terminology? See EOL vs EOS vs EOSL.
