Part 1: Compliance & Security Risk Awareness for FortiGate 100F EOL
Operating a firewall near its end-of-support introduces serious security risks. Unpatched FortiGate 100F devices are vulnerable to ransomware, malware, and other exploits. Non-compliance with regulatory standards such as PCI-DSS or ISO27001 can result in failed audits or canceled cybersecurity insurance coverage.
Official FortiGate 100F EOS/EOL Timeline:
Performance and compliance impact summary:
| Milestone | Date |
| End of Order (EOO) / End of Sale | April 16, 2026 |
| Last Service Extension Date (LSED) | April 16, 2030 |
| End of Support (EOS / EOSL) | April 16, 2031 |
The upcoming End of Order date means hardware replacements and expansions using the 100F will soon be impossible. Proactive organizations should start evaluating replacement options now to avoid security and compliance risks.
Part 2: FortiGate 100F Replacement Planning & Procurement
When planning for a FortiGate 100F replacement, IT procurement teams must balance continuous protection and cost-efficiency. The recommended successors are the FortiGate 120G or 200F, offering significant performance improvements.
Performance & Feature Comparison:
| Model | NGFW Throughput | Concurrent Sessions | 10GbE Ports | AI/ML Security |
| FortiGate 100F | 1.6 Gbps | 1.5M | 0 | Limited |
| FortiGate 120G | 3.1 Gbps | 3M | 2x10G SFP+ | Integrated |
| FortiGate 200F | 7 Gbps | 5M | 4x10G SFP+ | Advanced |
Budget Optimization & TradeUp:
Organizations can leverage the official FortiGate 100F TradeUp program to exchange legacy devices for discounted new hardware while transferring FortiCare and FortiGuard subscriptions.
Part 3: FortiGate 100F Migration & Technical Execution
Migrating from FortiGate 100F to 120G/200F without downtime requires careful planning:
Key Steps:
- Firmware Alignment: Ensure both legacy and new devices run the same FortiOS version.
- FortiConverter Service: Use this free tool for FortiGate-to-FortiGate upgrades; it automates interface mapping, configuration conversion, and policy migration.
- Phased HA Cutover: Set up the new cluster alongside the old one, establish BGP neighbors, and migrate VLANs/policies incrementally to limit downtime.
- License & Serial Verification: FortiToken Mobile licenses do not transfer automatically. Always verify serial numbers before deployment.
Following these steps ensures a smooth migration with minimal service disruption.
