Keep the SonicWall TZ670 under active protection with a 3-year Secure Upgrade Advanced Edition package that includes 1 year of CSE. This is built for teams that want to preserve security continuity while avoiding the overhead of managing separate support and subscription renewals. The TZ670 sits in environments where branch performance and policy enforcement matter. Extending coverage through a single package helps maintain the security services that support inspection, threat response, and ongoing firewall administration. The included CSE adds service continuity during the first year, which is especially useful when procurement cycles and operational timelines do not line up neatly. For IT organizations standardizing on SonicWall, this package offers a practical path to keep existing deployments current without forcing a hardware replacement. It supports predictable budgeting, reduces administrative overhead, and helps ensure the firewall remains covered through a longer planning horizon. When the goal is to sustain perimeter control and simplify lifecycle management, this renewal package delivers clear value.
