EOL
When a vendor has not published an exact date, we render an estimated range with an explicit confidence score — never an empty cell. See how to read TPM library records honestly.
Failure Outlook
Age: 6.8 years
Failure likelihood: 28%
Likely to fail (most → least)
- Dual internal PSU capacitor aging (non-hot-swap)
- NAND flash / eMMC wear on OS partition
- Fan bearing failure (sealed fan tray)

The FortiGate 100F reached End of Sale on 2026-04-16 but remains under full Fortinet support until 2031-04-16, meaning coordinated PSIRT advisories and FortiOS firmware patches continue to be issued. FortiOS-based appliances carry a historically high CVE volume — including several critical SSL-VPN and management-plane vulnerabilities exploited in the wild — making diligent patch cadence and management-interface isolation the single most important security control regardless of hardware age. Post-2031, organizations should formally document risk acceptance, enforce strict network segmentation so the appliance is not a single point of perimeter trust, and evaluate whether FortiGuard subscription services (which are licensed separately from hardware EOS) remain available; where compliance frameworks such as PCI DSS or HIPAA require vendor-supported components, a migration plan to a supported platform should be initiated before the EOS date.
Compensating controls that still work
- Restrict GUI and SSH management access to a dedicated out-of-band management VLAN; never expose the management interface to the internet.
- Disable SSL-VPN if not required, or enforce certificate-based authentication and IP allowlisting — SSL-VPN has been a frequent exploitation vector in FortiOS CVEs.
- Enable FortiGuard subscription services (IPS, AV, Web Filtering) and keep signatures auto-updated; FortiGuard telemetry is separate from hardware EOS and remains available while subscriptions are active.
- Subscribe to Fortinet PSIRT advisories (https://www.fortiguard.com/psirt) and apply FortiOS patches promptly — Fortinet's PSIRT tracks exploitation in the wild and typical attacker dwell time post-disclosure is under five days.
- After 2031-04-16 (EOS), maintain a compensating control register that documents accepted residual risk, segment the appliance behind a supported enforcement point, and align with your compliance framework's risk-acceptance provisions (e.g., NIST SP 800-137, ISO 27002 12.6.1).
Bushido publishes this information because it's the honest answer to the question "what changes at EOSL and what stays the same." We do not sell vulnerability management, patch orchestration, or MSP services — but you can find vendors who do in our vetted partners directory.

- Fortinet Support (hardware RMA) ↗ requires login
FortiGate hardware is replaced via RMA under FortiCare, not an open parts catalog.
No single manufacturer publishes a cross-vendor "alternative parts" list, and no one official aggregates across all vendors. Lenovo and HPE expose substitute chains publicly; Dell and Sun/Oracle keep them internal or gated. These links are the honest map of where each vendor's data actually lives. If a link is dead or a portal has moved, tell us and we'll fix it.

Standard Bill of Materials (at GA)
The FortiGate 100F (FG-100F) is a 1RU rack-mount next-generation firewall and secure SD-WAN appliance introduced in 2019. At general availability it shipped running FortiOS 6.2 on a Fortinet proprietary SoC4 system-on-chip that integrates an ARMv8 8-core host CPU, an NP6XLite network processor for hardware-accelerated firewall and VPN offload, and a CP9XLite content processor for SSL/TLS inspection acceleration. The base chassis provides 22 GE RJ45 ports (including 2 WAN, 1 DMZ, 1 MGMT, 2 HA, and 16 switch ports with 4 shared SFP media), 4 dedicated GE SFP ports, and 2 x 10 GE SFP+ FortiLink uplink ports. Memory is approximately 4 GB DDR4 (some board revisions ship with 8 GB). There is no onboard SSD on the base FG-100F (the FG-101F variant adds a 480 GB SSD). Power is provided by dual internal non-hot-swappable AC power supplies with an average draw of 35 W. The appliance ships without optics; SFP transceivers are ordered separately.

BOM reflects the standard base FG-100F configuration at GA (2019). The FG-101F variant adds a 480 GB onboard SSD and is otherwise identical. FortiGuard Unified Threat Protection (UTP) and Advanced Threat Protection (ATP) bundles are software subscription SKUs not enumerated here. Vendor part numbers for transceivers and support contracts are confirmed from Fortinet ordering information; the chassis PSU is internal and has no separate field-replaceable SKU for the 100F. Always cross-reference with the Fortinet support portal and your authorized distributor before ordering.
