Overview

The SONICWALL TZ370 SEC UPG PLUS ESST ED3Y is a 3-year security subscription designed for the SonicWall TZ370 UTM firewall. This license unlocks advanced protection features including gateway antivirus, intrusion prevention, application control, and content filtering, elevating the base TZ370 into a fully capable next-generation firewall.
Targeted at small to medium businesses and branch offices, this upgrade pack provides essential security services plus technical support for three years. It is a cost-effective way to maintain enterprise-grade threat defense without replacing the existing hardware.

Connectivity & Compatibility

This subscription is exclusively compatible with the SonicWall TZ370 hardware firewall. The TZ370 itself features one WAN port and four LAN ports (one configurable as DMZ), supporting up to 1 Gbps throughput. The license activates via the SonicOS firmware and can be managed through SonicWall's Network Security Manager (NSM) or on-premises management console.
Important compatibility notes: This SKU (SEC UPG PLUS ESST ED3Y) is specifically for upgrading the TZ370 from its standard security edition. It cannot be applied to other SonicWall models such as the TZ270 or TZ470. Activation overwrites any existing subscription period, so plan the timing carefully to avoid wasting remaining service days.

Product Info

The subscription is sold through SonicWall's official channel and authorized resellers. On online retailers, the price is approximately ¥229,437 (tax included) for the full 3-year term. The product was released alongside the TZ370 hardware around 2020 and remains actively sold.
Market positioning: This is a mid-range security subscription for an entry-level UTM firewall. While the TZ370 is SonicWall's most affordable model, adding this upgrade pack brings its security capabilities in line with mid-market requirements. The package includes only a license key card; no physical media is provided.

Best Use Cases

  • IT administrators in SMBs: If you already own a TZ370 and need stronger protection against ransomware and targeted attacks, this subscription enables gateway antivirus and IPS. It's a straightforward upgrade path. However, if your budget is tight, the standard edition still offers basic firewall functionality.
  • Organizations with branch offices: Deploy this subscription across multiple TZ370 units at remote sites to enforce consistent security policies. Combined with SonicWall's cloud management (NSM), it reduces operational overhead significantly.
  • Compliance-driven environments: For regulations like PCI DSS or HIPAA that require advanced logging and content filtering, the Essential Edition includes reporting tools that simplify audit preparation.
  • Long-term planners: Buying a 3-year subscription upfront eliminates annual renewal paperwork. Keep in mind that renewal after three years will incur additional costs.
