Technical Report: FortiGate 200D Firmware Status

End of Order (EOO)

Understanding the timeline of the FortiGate 200D helps in planning a hardware refresh. May 22, 2018 Last Service Extension Date (LSED) May 22, 2022 End of Support Date (EOS) May 22, 2023 Why You Must Upgrade Hardware

• Unpatched Vulnerabilities: Any CVEs discovered after October 2022 (for v6.2) or 2023 (for v6.0) remain unpatched. This includes high/critical SSL-VPN and authentication bypass vulnerabilities.
• Compliance Violations: Regulatory standards (PCI-DSS, HIPAA, NIST) generally prohibit using EOL firewall firmware in production environments.
• No Technical Support: Fortinet TAC will not provide bug fixes, security patches, or troubleshooting assistance for the 200D.

• Major Release (e.g., 6.2): Introduces new features.
• Minor Release (e.g., 6.2.15): Contains bug fixes and security patches.
• Maturity: FortiOS versions move from "General Availability" (GA) to "Mature," then "Feature Refresh," and finally to "Engineering End of Support."

• Stagger upgrades across HA pairs and across different sites to reduce risk.
• Test major upgrades in a lab or with a non-production unit if available.
• Regularly update signatures (AV/IPS) independently of major firmware upgrades.
• Keep an eye on End-of-Life/End-of-Support announcements for hardware and firmware branches.
