Frequently asked
When is the Fortinet FortiGate-3400E-DC end of life?
Fortinet's published notice sets End of Order for the FortiGate-3400E-DC at Apr 16, 2025. The published end-of-support date is Apr 16, 2030, after which vendor support ends. Check the milestones on this page and plan the refresh ahead of the support cutoff.
What replaces the Fortinet FortiGate-3400E-DC?
Fortinet has not named a one-for-one replacement in the notice this page is built from. Uniqcli can recommend and quote the current equivalent for the FortiGate-3400E-DC, with TAA country-of-origin screening on request.
Can I still buy or get support for the FortiGate-3400E-DC?
New units are no longer sold by Fortinet after the End of Order date; remaining channel stock and refurbished units are the only sources. Vendor support continues until Apr 16, 2030 under an active support contract. For a fleet still running this hardware, the practical next step is a refresh plan — request a quote and we will price the current replacement.
Send unit counts or a bill of materials — we price the current replacement, confirm stock and TAA country of origin, and return one reviewed refresh quote.
