SonicWall TZ105 next-generation firewall. Published last-order-day (end-of-sale) and end-of-support (EOSL) dates from SonicWall's public Product Life Cycle Tables, linked for verification.
Every tracked SonicWall TZ105 SKU group is past SonicWall end of service life (last group Sep 2020). Units in production should be treated as unsupported. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure.

Options from here
The SonicWall TZ105 is past SonicWall end of service life. These are the paths teams take from here:
Keep it in production past the OEM cutoff with an independent maintainer.
Buy spares now, while units still circulate on the secondary market.
It is unsupported today. Set a migration timeline and budget.
Low-criticality role: document the risk, harden backups, retire on your terms.
Independent and informational. EOSL.ai sells no hardware and no maintenance, and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the role the asset plays.
