Protect the branch without slowing the business. SonicWall TZ370 Secure Upgrade Advanced Edition delivers the security stack needed for sites that carry real traffic, real users, and real risk. With intrusion prevention, application control, sandboxing, and encrypted traffic inspection, it is designed to stop threats that basic firewalls miss. This 3-year package includes 1 year of CSE coverage, giving IT teams a clearer path for planning and renewal management. That matters when you are standardizing security across multiple locations and need predictable coverage, consistent policy enforcement, and fewer gaps between license cycles. The TZ370 is a strong fit for organizations that want more headroom than entry-level appliances provide. It supports VPN and SD-WAN use cases, central management, and logging/reporting workflows that help security teams see what is happening at the edge. For buyers comparing price points, the value is in the combination of performance, control, and subscription coverage — not just the hardware alone.
