Frequently asked
When is the Fortinet FortiGate-400D-LENC end of life?
Fortinet's published notice sets End of Order for the FortiGate-400D-LENC at May 8, 2018. The published end-of-support date is May 8, 2023, after which vendor support ends. It is past its published support window — plan the refresh now.
What replaces the Fortinet FortiGate-400D-LENC?
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-400D-LENC, with TAA country-of-origin screening on request.
Can I still buy or get support for the FortiGate-400D-LENC?
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 has ended (May 8, 2023), so security fixes and hardware replacement from Fortinet are no longer available. 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.
