FortiGate 1240B G End of Life
Understand when support ends and how to future-proof your FortiGate 1240B G End of Life deployment.

The FortiGate-1240B-G has reached its end of life and will eventually stop receiving full lifecycle support. Organizations using the FortiGate-1240B-G should plan modernization to maintain security consistency and meet growing performance demands.
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-1240B-G Date & Status
Here’s what you need to know about FortiGate-1240B-G lifecycle status.
- End of Life (EOL): 1/14/24

FortiGate-1240B-G Replacement
Replacing the FortiGate-1240B-G isn’t just about swapping hardware. It’s an opportunity to reassess architecture, address emerging threats, and align with current operational and cloud-first requirements.
Role of the FortiGate-1240B-G:
Designed for high-performance campus or data center perimeter deployments, delivering advanced firewalling, high-speed VPN, and scalable interface options.
Evolving Traffic Patterns:
Networks now handle denser east-west flows, widespread cloud application use, and heavier encrypted streams—pressuring inspection engines, session capacity, and interface throughput.
Modern Demands:
Enterprises require hardware-accelerated inspection, unified threat management, integrated SD-WAN, and centralized lifecycle management to reduce complexity and improve availability.
Strategic Upgrade:
Conduct a capacity and policy gap analysis, then select modern FortiGate appliances or hybrid cloud/SASE solutions offering higher throughput, enhanced TLS inspection, and unified orchestration.
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.
