Fortinet FortiGate-101E end of life: end of support dates

FortiGate-101E lifecycle milestones

The date below is read live from our curated reference table, sourced from Fortinet Product Life Cycle export, End of Support Date column (support.fortinet.com, hardware list).

What the date means

Fortinet publishes a dated lifecycle for every hardware part number rather than a blanket policy, and the End of Support date is the one that governs. It sits well after End of Order, which is why a unit can be years past the point of being buyable and still fully supported. The gap is generous by industry standards and it is also the reason FortiGate estates drift: nothing changes on the box on either date, so the milestone passes unnoticed unless somebody is tracking it.

A firewall past End of Support is the worst version of this problem. It sits on the perimeter by definition, it terminates remote access, and it is the single device an attacker most wants a known unpatched version of. Vulnerabilities disclosed after the date are never fixed on it, and firewall CVEs are routinely exploited within days of publication. Cyber insurance questionnaires and most compliance frameworks now ask specifically whether perimeter devices are vendor-supported.

For the full vendor policy see the Fortinet EOL guide, and if the terminology is the confusing part, EOL vs EOS vs EOSL separates the three milestones that get used interchangeably.

What replaces the FortiGate-101E?

Fortinet has not published a named one-to-one successor for the FortiGate-101E, which is the common case outside of RUCKUS lifecycle notices. The practical approach is to pick the current model in the same product line at similar capacity, then check its End of Support date before ordering rather than after.

The table below is that shortlist: the FortiGate firewalls still in support, soonest deadline first, so you can see how much runway each option actually buys you.

Sorted by how much supported life is left, shortest first. Anything already past its date is left out, because it is not a replacement for anything.

Common questions

When does the Fortinet FortiGate-101E reach end of support?

The Fortinet FortiGate-101E reached End of Support on July 15, 2026. It no longer receives firmware or security updates and is not eligible for support or hardware replacement.

Does a firewall stop working at end of support?

No. The firewall keeps passing traffic. What stops is firmware fixes, vendor support and hardware replacement under contract, so any vulnerability disclosed after that date is never patched on that unit.
