FortiGate 100E End of Life
Understand when support ends and how to future-proof your FortiGate 100E End of Life deployment.

The FortiGate-100E has been a widely deployed mid-range next‑generation firewall for branch and campus edge deployments. It has reached end of life, and now is the time to assess how to modernize your security stack to maintain resilience, performance, and vendor support as traffic patterns and integrations evolve.
What this means for your organization
- A chance to modernize your security posture and prepare for future growth.
- Opportunity to benefit from improved performance, efficiency, and protection.
- Align IT infrastructure with compliance, scalability, and long-term ROI.
FortiGate-100E Date & Status
Here’s what you need to know about FortiGate-100E lifecycle status.
- End of Life (EOL): 8/17/26

FortiGate-100E Replacement
Replacing the FortiGate-100E ensures mid-sized branches can support encrypted and cloud-driven workloads at scale.
Role of the FortiGate-100E:
A mid-range NGFW for edge security and VPN/UTM consolidation.
Evolving Traffic Patterns:
Cloud-bound, encrypted traffic requires deeper inspection and SD-WAN integration.
Modern Demands:
Stronger TLS visibility, SD-WAN orchestration, cloud workload protection, and ML-driven prevention.
Strategic Upgrade:
Adopt replacements with improved capacity, SASE/SD-WAN integration, and centralized management with staged migration.
Understanding Fortinet's EOL Policy | End of Life Risks
Every Fortinet product follows a defined lifecycle, moving through the following stages:

- 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.
Risks of Continuing to Use EOL Hardware
When a firewall or security appliance reaches End of Life, the risks of keeping it in production increase dramatically
No Security Patches
Outdated devices won’t receive updates, leaving your network exposed to new vulnerabilities.
Lack of Vendor Support
Once support ends, there’s no access to Fortinet’s technical resources or RMA services.
Compliance Failures
Auditors may flag unsupported hardware as a violation of security and industry standards.
Operational Instability
Legacy devices may struggle with modern workloads, encrypted traffic, and cloud integrations.
