Cisco Firepower appliances (hardware) lifecycle status — the real story
Cisco Firepower appliances are the firewall hardware under Cisco Secure Firewall Threat Defense (FTD) and Cisco ASA software: the Firepower 2100 series, the Firepower 4100 series (4110 to 4150 and 4112 to 4145), the Firepower 9300 chassis and its SM-24, SM-36 and SM-44 security modules. Cycles on this page are appliance models, so it is the hardware companion to the Cisco FTD and Cisco ASA software pages, where the exploited CVEs that put these firewalls in CISA's KEV catalog are tracked. Every date comes from Cisco's own End-of-Sale and End-of-Life bulletins on cisco.com (public, no login), one bulletin per family, each cited on its cycles. Each bulletin was read twice on 2026-10-16: the bulletin HTML fetched with a browser header set and the same bulletin in the built-in browser; every milestone identical (tools/cisco-hardware-bulletins.mjs refuses to write on any difference). Cycles are models; each lists the chassis part numbers Table 2 of its bulletin retires (base, spare and bundle forms). A model gets a cycle only when its own chassis part number is in Table 2; where Cisco titles a bulletin select, the cycles are the exact part numbers it retires. Current models without a bulletin are not listed; their absence is not a statement that they are supported indefinitely.
Field mapping, the Cisco hardware convention of the Cisco ASA 5500-X and Cisco RV pages: support is Cisco's End-of-Sale Date ('The last date to order the product through Cisco point-of-sale mechanisms'); eol is Cisco's Last Date of Support ('The last date to receive applicable service and support for the product as entitled by active service contracts or by warranty terms and conditions. After this date, all support services for the product are unavailable, and the product becomes obsolete'). The other Table 1 milestones (End-of-Life Announcement, Last Ship, End of SW Maintenance Releases, End of Vulnerability/Security Support, End of Routine Failure Analysis, End of New Service Attachment, End of Service Contract Renewal) are carried under their own names where the bulletin prints them; a milestone the bulletin does not print is empty. Cisco bulletins print no launch date, so releaseDate is empty.
Bulletins that retire only subscriptions or licences for these appliances are not modelled. The Firepower 1000 series and Secure Firewall 3100 and 4200 series have no hardware End-of-Sale bulletin and are not listed.
Cisco Firepower appliances (hardware) release and support pattern
Of the 16 release lines tracked, 6 are past end of life and 10 are still within support. The next scheduled end of life is Firepower 4110 on January 31, 2027 — 105 days from this build. The longest-supported line currently published is Firepower 9300, to March 31, 2031.

What does Cisco Firepower appliances (hardware) end of life mean for your organization?
When a version of Cisco Firepower appliances (hardware) reaches end of life, the maintainers stop issuing security patches. Vulnerabilities discovered after this date are publicly disclosed on the National Vulnerability Database, exploit code appears on GitHub, and your systems remain permanently exposed.
The CVE blind spot: A CVE-based scan does not show the accumulation of unpatched vulnerabilities in EOL software. Some scanners flag unsupported versions of common products, but coverage varies, and none of them give you the date in advance. With a zero-day, nobody knows about the vulnerability. With EOL software, the vulnerability is public — listed, rated, and often weaponized — but no vendor patch is coming. This is one of the most dangerous gaps in enterprise security posture.
Organizations running EOL Cisco Firepower appliances (hardware) should treat it as a vulnerability class in their risk register, apply compensating controls (network segmentation, enhanced monitoring, access restriction), and prioritize migration to a supported version.
Your options when Cisco Firepower appliances (hardware) reaches end of life
There are four realistic paths. Which one is right depends far more on how long the system needs to keep running than on the version you are on today.
| Option | Best when | Watch out for |
|---|---|---|
| Move to a supported version | The system will outlive the current version's support window and you can schedule the work | Budget for compatibility testing, not just the upgrade itself — that is where the real cost sits |
| Replace the component | The project is unmaintained, or a better-supported alternative exists | The replacement has its own lifecycle and its own end-of-life date — you are changing vendors, not escaping the problem |
| Buy extended support | Migration is genuinely underway but cannot finish before the deadline, or the workload is frozen by certification or a third-party application | A bridge, not a destination — every year purchased is a year the migration still has to happen |
| Document accepted risk | The system is isolated, short-lived, or scheduled for retirement | Only defensible with real compensating controls and a written decision — auditors treat undocumented end-of-life software as a finding |
How to choose, in one question: how many more years does this system need to run? Under a year, extended support (where it exists) is usually cheaper than an emergency migration. One to three years, migrate — support purchased repeatedly costs more than doing the project once, and the project only gets harder as the version ages. Indefinitely, migrate now and plan the next migration before it surprises you.
Worth saying plainly, because vendors selling extended support rarely will: extended support is often the more expensive choice over a multi-year horizon. It is the right answer when a deadline is genuinely unreachable, not as a default. Compare the annual fee against the one-time cost of migrating before committing to either.

Extended Support Options
If you cannot migrate immediately, extended support vendors provide continued security patches for EOL Cisco Firepower appliances (hardware) versions. This is a bridge, not a permanent solution — plan your migration in parallel.
Cisco Firepower appliances (hardware) has 6 versions past end of life — security patches have stopped, but CVE disclosures haven't. Extended support past the official date exists for many products in this position — whether it exists for Cisco Firepower appliances (hardware) is exactly what we check. Tell us where to reach you and we'll reply with matched options and pricing guidance — or an honest "no vendor covers this."
