SonicWall SMA 100 lifecycle status — the real story
SonicWall SMA 100 series (SMA 200, 400, 210, 410 and the virtual 500v) are the SSL-VPN appliances behind repeated exploitation waves — the series has accumulated CISA KEV entries from the 2021 campaign (CVE-2021-20016, CVE-2021-20038 among them) through 2025 (CVE-2021-20035 added April 2025, CVE-2023-44221 added May 2025). It is exactly the appliance class CISA’s BOD 26-02 orders end-of-support discipline for.
Every SMA 100 model is now past End of Support. Per SonicWall’s Product Lifecycle Tables: SMA 200 and 400 reached End of Support on June 18, 2025, and SMA 210, 410 and 500v on November 1, 2025. SonicWall’s lifecycle definition for the final phase is unambiguous — no support, no firmware, no hardware replacement. Firmware (10.2.x) support rode the hardware dates; the last listed 10.2.1.x build shipped December 2024.
Provenance note: SonicWall’s hardware table publishes phase dates (Last Order Day → retirement phases → End of Support) but not original launch dates — the release column is therefore left blank rather than substituting a proxy (each model’s Last Order Day is on the linked lifecycle table); the active-support column shows the vendor’s 1-Year Support Last Order milestone. The successor products are the SMA 1000 series appliances and SonicWall’s cloud secure-access offerings.
SonicWall SMA 100 release and support pattern
Of the 5 release lines tracked, 5 are past end of life and 0 are still within support.

SonicWall SMA 100 security intelligence
CISA KEV history: SonicWall SMA 100 is named in CISA's Known Exploited Vulnerabilities catalog 1 time, most recently on 2022-01-28, including use in ransomware campaigns. Derived from CISA's live catalog at every build.
What does SonicWall SMA 100 end of life mean for your organization?
When a version of SonicWall SMA 100 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 SonicWall SMA 100 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 SonicWall SMA 100 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 SonicWall SMA 100 versions. This is a bridge, not a permanent solution — plan your migration in parallel.
SonicWall SMA 100 has 5 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 SonicWall SMA 100 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."
