Keep a TZ370 deployment protected with a 2-year secure upgrade threat package designed to preserve security coverage on the appliance you already trust. This is the practical path for teams that want to extend protection without changing the network edge, re-cabling the site, or introducing a new platform to qualify. For small offices, branch locations, and distributed environments, the value is continuity: consistent firewall policy enforcement, ongoing threat visibility, and a cleaner procurement cycle tied to the existing SonicWall footprint. That matters when the firewall is sitting in front of business-critical applications, remote users, and internet-bound traffic that cannot afford gaps in coverage. This package is well suited to organizations that prefer to standardize on a known security stack and keep support aligned to the installed base. It helps preserve the operational model your team already understands while extending the protection window for another 2 years. For buyers comparing lower-cost alternatives, the difference is not just price — it is the confidence that comes from keeping the environment stable, supported, and ready for the next planning cycle.
