Dates are from Fortinet's Product Life Cycle page in the FortiCloud support portal (free login required). End of Order is shown as end of sale and End of Support as last date of support. The last date to renew a service contract (Last Service Extension Date) is 31 Dec 2025. Last supported FortiOS version: 7.2. The 1500D-DC, -LENC and -USG variants have different dates.
What this means for your business
- Security patches stop when support ends, so the exposure starts on that date.
- Cyber insurance questionnaires increasingly ask whether any equipment is unsupported or past end of life.
- Vendor support for faults ends at the same time.
- This is general information, not legal or insurance advice.
Replacement options
Vendor-neutral options to consider:
- Palo Alto Networks PA-400 series
- Ubiquiti UniFi Cloud Gateway
- MikroTik RouterOS appliances
The right replacement depends on your sites, users and licensing, and is often cheaper than a like-for-like swap.
Keep or replace? Quick checklist
- Is it your internet-facing firewall?
- Do you have remote staff connecting through it?
- Is your cyber insurance renewal in the next 6 months?
- Do you store client or financial data behind it?
- Is it running old firmware, or does it have no active vendor licence?
Two or more “yes” answers on an unsupported or soon-to-be-unsupported device is a good reason to get advice.
Frequently asked questions
Is the FortiGate 1500D still safe to use?
For now, yes, but support ends soon. After that date Fortinet stops issuing security fixes, so plan a replacement before then.
What replaced the FortiGate 1500D?
Fortinet's bulletin does not name a direct replacement that we've verified. The right choice depends on your sites, users and licensing.
