For IT managers responsible for network security, one of the most critical pieces of information is the End of Support (EOS) and End of Life (EOL) schedule for their deployed equipment. Fortinet’s FortiGate firewalls are among the most widely deployed next-generation firewalls (NGFW) globally, making it essential to understand the lifecycle of both hardware models and FortiOS software.
2025 is particularly significant, as many FortiGate models and FortiOS versions are reaching important transition points. This guide provides systematic, actionable EOS/EOL information based on the latest data for immediate practical use.
1. Understanding Fortinet Product Lifecycle
1-1. Key Terminology
To properly understand Fortinet’s product lifecycle, you need to be familiar with these essential terms:
EOO (End of Order)
- Last date a product can be ordered
- No new purchases available after this date (existing inventory only)
LSED (Last Service Extension Date)
- Final date existing support contracts can be extended
- Typically 12 months before EOS date
EOES (End of Engineering Support)
- Date when software engineering support ends
- Only critical security vulnerabilities receive patches after this point
EOS (End of Support)
- Complete support termination date
- Hardware: 60 months (5 years) after EOO
- Software: 54 months (4.5 years) after GA release
1-2. Hardware vs Software Lifecycle Independence
A unique aspect of Fortinet’s approach is that hardware and software lifecycles operate independently.
Lifecycles
| Component | Hardware | Software (FortiOS) |
|---|---|---|
| Engineering Support | N/A | 36 months post-GA |
| Complete Support End | 60 months post-EOO | 54 months post-GA |
| Impact Scope | Hardware RMA, tech support | Bug fixes, features, security patches |
