FortiNAC 9.4 End of Support Is November 13, 2026

By Scott Bissett  ·  Published: October 7, 2026  ·  Reference guide  ·  Dates read at Fortinet's Product Life Cycle page (support.fortinet.com, Software tab, FortiNAC and FortiNAC-F entries) on October 7, 2026.

FortiNAC 9.4 reaches end of support on November 13, 2026. That is the End of Support Date (EOS) Fortinet prints for the 9.4 row of its Product Life Cycle page, and it is the second of two end dates on that row: the first, End of Engineering Support Date (EOES), was May 13, 2025, thirty-six months after the branch's general availability on May 13, 2022. Between the two dates the branch is in the phase Fortinet's policy calls "Must Fix" support. 9.4 is also the last branch Fortinet lists under the FortiNAC name; its successor line is FortiNAC-F, which Fortinet lists as a separate product with its own dates.

Fortinet's two dates, in Fortinet's words

Fortinet prints its software support policy directly above the life cycle tables, and the policy explains why every FortiNAC row carries two end dates. Fortinet provides "Engineering Software support for thirty six (36) months from the GA release date" of a major or minor release. It then provides what the policy calls "Must Fix" support for a further eighteen months from the End of Engineering Support date. The policy also states that "Software Releases" are major or minor version increments and that support is provided on the latest patch release of each version.

• End of Engineering Support Date (EOES). The end of the thirty-six-month engineering window. For FortiNAC 9.4 this was May 13, 2025. Our data serves it as the branch's support date.
• End of Support Date (EOS). The end of the eighteen-month Must Fix window that follows. For FortiNAC 9.4 this is November 13, 2026. Our data serves it as the branch's eol date.

Two consequences follow from the policy's own wording. First, a branch between its two dates is still supported, but only for fixes Fortinet classes as must-fix; the regular engineering release stream has ended. Second, because support is provided on the latest patch release of each version, a 9.4 deployment that is behind the newest 9.4 patch is outside the policy even before November 13, 2026. The 9.4 release notes on Fortinet's documentation site run to 9.4.8 as of this writing; check the FortiNAC 9.4 documentation for the current patch before assuming coverage.

Every FortiNAC branch Fortinet lists

These are the eight rows of the FortiNAC entry on Fortinet's Product Life Cycle page, read on October 7, 2026, with Fortinet's column names. Fortinet prints the 9.1 row as "9.1*"; the page shows no footnote for the asterisk, and we carry the row as printed. Each branch links to its live status page.

Every date in the table matches Fortinet's page to the day. Seven of the eight branches are past End of Support; 9.4 is the only FortiNAC branch still inside a support phase, and it has no successor under the FortiNAC name.

FortiNAC and FortiNAC-F: which dates belong to which

Fortinet's documentation library carries a note on the FortiNAC product page: FortiNAC is now named FortiNAC-F, and post-9.4 documentation is published under FortiNAC-F. The FortiNAC-F page in turn points readers to the FortiNAC 9.4 library for what it calls legacy FortiNAC documentation, pre-FortiNAC-F 7.2. On the Product Life Cycle page the two names are separate entries. The FortiNAC entry holds the eight 8.x and 9.x branches in the table above. The FortiNAC-F entry holds three branches, 7.2, 7.4 and 7.6, each with its own Release Date (GA), End of Engineering Support Date and End of Support Date, all of them later than the FortiNAC 9.4 dates.

Every date on this page belongs to the FortiNAC entry. We do not yet serve the FortiNAC-F rows, so we do not print them here; they are on the same Fortinet page, under the FortiNAC-F heading, for anyone planning the move. The FortiNAC-F 7.6 documentation lists release notes through 7.6.7 as of this writing, which makes 7.6 the newest line Fortinet publishes.

What to do with the time you have

1. Inventory by branch and patch. Record the exact version of every FortiNAC Control and Application server and every FortiNAC Manager. Fortinet's policy covers the latest patch release of each version, so the patch number matters, not just the 9.4 label.
2. Put both 9.4 dates in the plan. May 13, 2025 has passed, so 9.4 is already limited to Fortinet's Must Fix support; November 13, 2026 ends that phase, and Fortinet's table lists nothing after it.
3. There is no later FortiNAC branch to move to. 9.4 is the last row under the FortiNAC name on Fortinet's page, so staying within 9.x means staying on 9.4 at its latest patch until End of Support. The forward path Fortinet documents is FortiNAC-F.
4. Follow Fortinet's own migration documents for FortiNAC-F. The FortiNAC-F 7.6 documentation library includes a set titled "CentOS to FortiNAC-OS Migration Guides", with separate guides for VM and hardware deployments and for combined and separate Control and Application servers. Fortinet's 9.4 release notes also state that FortiNAC cannot go backwards to a previous version, so test the move before committing production servers. Use Fortinet's guides for the procedure; this page records only the dates.
5. Treat the appliance as an edge system. A network access control server decides which devices get onto the network, so it belongs on the same end-of-support watchlist as firewalls and VPN gateways. FortiNAC is one of the platforms on our edge-device end-of-support list, and our EOL Checker and API cover the operating systems and databases around it.
