Can I Still Use My FortiGate After End of Support?
Last updated: October 2026
Yes, you can use a FortiGate after end of support. It keeps running. But Fortinet has no duty to support it, gives no new firmware, and makes no commitment to FortiGuard updates. The risk grows each month. Plan the replacement before the end-of-support date.
Megatron Technology is a Fortinet reseller in Singapore. This post covers an unsupported unit. For an expired licence on a supported unit, read FortiGuard Expired.
