FortiGate EOL List: End-of-Life Fortinet Models

Aug 10 , 2026 7

TL;DR: Fortinet has phased out the older D-series FortiGates (300D, 500D, 600D, 800D, 900D) and is moving E-series models like the 60E, 100E and 200E into the later lifecycle phase, with F-series units as successors. This page lists the main EOL FortiGate platforms and what to check when buying them used.

FortiGate End-of-Life Status at a Glance

Fortinet handles EOL differently from most vendors: hardware lifecycle and FortiOS version support run in parallel, so a model can be "end of sale" while its FortiOS train still receives updates. The table below summarizes the current picture for the most traded models:

Why FortiOS Support Matters More Than the Hardware

FortiGates are sold with FortiOS, and the firmware train defines security support. A hardware EOL is less painful if the model still runs a supported FortiOS major version. For used buyers this means: confirm both the model’s hardware EOL date and the FortiOS version it runs, then map the remaining support window against how long you plan to use the unit.

Upgrade Paths for the Most Common Models

60E to 60F

The pre-owned FortiGate 60E is still an excellent small-branch firewall, but new deployments should look at the 60F for the longer firmware runway. In the used market, 60E units are cheaper and plentiful — match the unit to how long you expect to keep it.

100E and 200E

The 100E/200E follow the same pattern: mature, widely deployed, and slowly yielding to the F-series. For a 3-year horizon, a tested used 100E is hard to beat on price; for 5+ years, pay the premium for an F unit.

D-series

D-series units have completed their lifecycle. Buy them only for labs, training or non-critical segments where the final firmware is acceptable, and treat them as non-upgradeable.

Buying Used FortiGate: What to Check

• Serial verification: ask the seller to check the serial on Fortinet’s support portal, or do it together before payment.
• Firmware and support window: confirm the installed FortiOS major version and how much support remains for that model.
• Licenses: FortiCare/FortiGuard subscriptions generally do not transfer — factor a new subscription into the total cost if you need security services.
• Testing: the seller’s documented testing process should cover boot, ports and a factory reset before shipping.
• Warranty: confirm warranty terms in writing — for a firewall, a DOA swap matters more than cosmetic grade.

FAQ

Q: Is the FortiGate 60E end-of-life?

A: The FortiGate 60E has entered the later phase of its lifecycle: FortiOS support for the 60E continues on the current train, but Fortinet has moved new sales to the 60F and 70F. Check the Fortinet support site for the exact hardware EOL date for your unit.

Q: Are FortiGate D-series models end-of-life?

A: Yes. Older D-series platforms such as the 300D, 500D, 600D, 800D and 900D have completed their lifecycle and receive no new FortiOS releases. They remain usable on the final firmware they received, which is why tested units sell at steep discounts for lab and low-risk roles.

Q: Can I use a used FortiGate without a FortiGuard license?

A: Yes, the firewall policies and routing work without a license. What stops is the FortiGuard services: antivirus, IPS and web filtering signatures. A used unit is fine for network functions, but budget for a subscription if you need the security services.

Q: What happens when FortiOS reaches end of support on my model?

A: No more firmware releases, bug fixes or security patches for that model. The device keeps running the last installed firmware. For internet-facing firewalls this is a risk, so plan migration to an F-series unit before that date.

Q: What is the replacement for the FortiGate 60E?

A: The FortiGate 60F is the direct successor with similar port layout and higher throughput; the 70F adds more interfaces. In the second-hand market the 60E remains a solid value for branch sites because of the large installed base and mature firmware.

Q: Is it safe to buy a used FortiGate firewall?

A: Yes, with the same precautions as any used appliance: verify the serial number on Fortinet’s registration portal, confirm the firmware version, and buy from a seller whose testing process includes boot and port checks plus a warranty. Factory-reset the unit before deployment.
