SonicWall DNS Filtering Service for TZ370 4-Year | Security Subscription

Strengthen TZ370 security with SonicWall DNS Filtering Service, a 4-year subscription that moves domain control to the DNS layer. By stopping access to risky destinations before a connection is made, this service helps reduce exposure to phishing, malware infrastructure, and sites that violate corporate policy. For security teams, that means earlier enforcement and fewer gaps than controls that wait until traffic is already in motion. This service is built for organizations that want practical protection without adding endpoint complexity. It fits branch offices, distributed workforces, and environments where users need fast, consistent access decisions backed by centralized policy. Compared with lower-tier filtering options, a SonicWall subscription tied to the TZ370 gives you tighter alignment with the firewall platform and a cleaner operational model for long-term use. A 4-year term also supports procurement planning. It helps lock in coverage across a meaningful lifecycle window while keeping administration straightforward. For teams standardizing on SonicWall, this is a focused way to extend the value of the TZ370 and add a control layer that directly reduces risk at the point of domain resolution.
