Fortinet offers the following major lifecycle milestones:
-
End of Order (
EOO): is last date on which a product may be ordered. -
Last Service Extension Date (
LSED): The last date at which a service extension is accepted for an existing contract, for a hardware or software product. This is 12 months before the EOS date for most products, and 90 days after the End-of-life notification for stand-alone services. -
End of Engineering Support for Software (
EOES): The date beyond which Fortinet no longer commits to provide engineering support for software. After this date the software enters a must-fix support phase, during which maintenance builds will only be produced for industry-wide critical issues and PSIRT vulnerabilities. The EOES date is generally 36 months after the GA date. -
End of Support Date (
EOS): Fortinet will not sell, manufacture or improve the product after this date and is under no obligation to provide support services. In general the EOS takes place as follows:- Hardware — 60 months after the EOO Date
- Software — 54 months after the GA date
- Stand-alone Services — on the service contract termination date
