WatchGuard Firebox lifecycle status — the real story
WatchGuard Firebox and XTM appliance lifecycle from WatchGuard's own End of Life policy page (fetched directly and verified 2026-09-02; the page is plain-HTML and machine-checkable). Cycles are hardware models — WatchGuard publishes per-model End-of-Sale and End-of-Life dates, not per-Fireware-version dates. Milestone mapping: eol = the model's End of Life date ('conclusion of development and support'); support is left null because WatchGuard's published support milestone IS the EOL date — 'Customers with an active Support subscription will receive continued technical and limited software support until the End of Life.' releaseDate is null: WatchGuard does not publish launch dates on this page and we do not substitute proxies. Each model's End-of-Sale date (up to five years before EOL) is on the linked page.
Scope: Firebox T/M-series, M440/M4600/M5600, and the XTM models and XTMv virtual line whose EOL falls on or after 2020-01-01 (66 models). XTM models that reached EOL before 2020 are omitted; WatchGuard's page retains them.
KEV context: four exploited CVEs — CVE-2022-26318 ('Firebox and XTM Appliances') and CVE-2022-23176 ('Firebox and XTM', the Cyclops Blink botnet CVE), plus CVE-2025-9242 and CVE-2025-14733 (product 'Firebox'). The 2025 KEV additions landed while the T35/T55/T70 cohort was months from its 2025-12-31 EOL — those models are now past EOL, and the XTM appliances named in the 2022 entries passed EOL 2023-12-31 at the latest.
WatchGuard Firebox release and support pattern
Of the 66 release lines tracked, 41 are past end of life and 25 are still within support. The next scheduled end of life is Firebox T35-R on March 1, 2027 — 180 days from this build. The longest-supported line currently published is Firebox M290, to July 1, 2031.
Computed from the tracked release data at every build — the figures above are the dates in the table, restated, not an editorial estimate.
WatchGuard Firebox security intelligence
CISA KEV history: WatchGuard Firebox is named in CISA's Known Exploited Vulnerabilities catalog 4 times, most recently on 2025-12-19. Derived from CISA's live catalog at every build.
What does WatchGuard Firebox end of life mean for your organization?
When a version of WatchGuard Firebox 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: Most vulnerability scanners check for known CVEs but do not flag the accumulation of unpatched vulnerabilities in EOL software. With a zero-day, nobody knows about the vulnerability. With EOL software, the vulnerability is public — listed, rated, and often weaponized — but no patch will ever exist. This is the most dangerous gap in enterprise security posture.
Organizations running EOL WatchGuard Firebox 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 WatchGuard Firebox 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 WatchGuard Firebox versions. This is a bridge, not a permanent solution — plan your migration in parallel.
WatchGuard Firebox has 41 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 WatchGuard Firebox 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."
