Understanding Fortinet's EOL Policy | End of Life Risks

Every Fortinet product follows a defined lifecycle, moving through the following stages:

help-3-1
  • General Availability (GA): The product is released and actively sold and supported.
  • End of Sale (EOS): The device is no longer available for purchase from Fortinet or authorized partners.
  • End of Life (EOL): Feature development and most firmware updates stop.
  • End of Support (EOSL): Fortinet ends all official support, security patches, and RMA services.

Why This Matters for Your Business

Understanding where your hardware sits in this lifecycle helps you:

  • Plan timely upgrades before critical support ends.
  • Ensure security compliance and avoid audit failures.
  • Maintain operational continuity with fully supported hardware.
