Navigating to the Firmware Section: Once in the support area, navigate to the firmware or software updates section. You may need to select your product model and the version you're currently running to find the appropriate update.

1. Upgrade Hardware to Gen 6 (minimum) – A used TZ 400 or NSA 2600 runs SonicOS 6.5, still receiving essential security updates.
2. Switch to Cloud-Managed Firewall (SonicWall NSv) – If virtualized, run NSv for AWS/Azure with modern features.
3. Convert SonicWall to Layer 2 Bridge Mode – Place an EOL unit as a transparent IPS only.
4. Third-party open-source (pfSense/OPNsense) – Can be installed on x86 hardware for cheap but requires full reconfiguration.

⚠️ If you no longer have a valid support contract, you may not be able to download older firmware from the portal. In that case, contact SonicWall support or your reseller.
