Fortinet offers the following major lifecycle milestones:

  1. End of Order (EOO): is last date on which a product may be ordered
  2. 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.
  3. 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.
  4. 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
